In addition, in some embodiments, an electronic computing device such as a notebook or laptop computer as described herein may also be used to provide user interface panel functionality in place of, or in addition to, keypad 104 or similar components.

The base assembly may further include one or more folding, bendable, and/or deployable/retractable wing elements. For example, in an exemplary embodiment, the base assembly of platform 100 may include a front folding wing 112 and a rear folding wing 114. In FIG. 1, the rear folding wing 114 is shown partially rotated toward an open position. The base assembly may further include additional mechanical and/or mounting components such as side panels 118 and 120 as shown in FIG. 2 and FIG. 3.

A plurality of fasteners, such as screws 116, may be used to mount the front platform 108 and the rear platform 110, to right side panel 118 and left side panel 120 to form a shape suitable for mounting above or on a corresponding pipe inspection system. A strap anchor 122, which may be made of formed plastic or other materials may be disposed on the bottom edge of the right side panel 118 toward the forward end. A front right rubber foot 124 and a rear right rubber foot 126 may be disposed on the surface of the right side panel 118 with screws (not shown). An interface bus cable, such as USB cable 127, may be used to provide an electrical signal connection between the camera controller platform 100 and an electronic computing device, such as a laptop computer 202 (as shown in FIG. 7).

The camera controller platform 100 may include friction elements such as a front anti-slip mat 128 disposed on the surface of the front platform 108, a rear anti-slip mat 130 disposed on the surface of the rear platform 110, and/or an array of anti-slip squares 131 disposed on the surface of a surface of the front folding wing 112 and the rear folding wing 114.

Turning to FIG. 2, a left side perspective view illustrates additional details of the camera controller platform embodiment 100. The left side panel 120 may support a front cord wrap 132 and a rear cord wrap 133 for providing storage for the USB cable 127 which may be stored as shown in, for example, FIG. 7. A capstan may include a capstan knob or handle 134 disposed on the left side panel 120 of camera controller platform 100, which may be coupled to a capstan assembly 180, such as shown in FIG. 7 and FIG. 8, to provide a tensioning mechanism for a rubber elastic O-ring band 204 (as shown in FIG. 7 and FIG. 8) when securing a laptop computer 202 or other electronic computing device to the camera controller platform 100. The USB cable 127 is partially visible behind the left side panel 120, connected to a USB port 135 (not shown in FIG. 2).

FIG. 3 is an exploded view illustrating additional details of the camera controller platform 100 embodiment. The rear folding wing 114 may include a left rear molded hinge cylinder 136 and a right rear molded hinge cylinder 140, which may extend from the ends of a left rear arm 138 and a right rear arm 142, respectively. In assembly, the left rear molded hinge cylinder 136 and the right rear molded hinge cylinder 140 may each be seated into a left rear lower receptacle 144 and a right rear lower receptacle 148, respectively, which may be formed in a rear case bottom 146 of the base assembly.

A rear case top 150 may be formed with two outer surfaces, and may be positioned at an angle of approximately 30 degrees to one another, which may constitute the outer surface of the rear platform 110 and of the rear panel 106 (as shown in FIG. 1 and FIG. 2). A left rear upper receptacle 152 and a right rear upper receptacle 154 may each be disposed on the platform, such as on the inner surface of the rear case top 150 as shown. In assembly, left rear upper receptacle 152 and right rear upper receptacle 154 each mates with left rear lower receptacle 144 and right rear lower receptacle 148, respectively, which movably contains left rear molded hinge cylinder 136 and right rear molded hinge cylinder 140 to provide a flexible hinge.

Still referring to FIG. 3, the front folding wing 112 may include a left front molded hinge cylinder 156 extending from the end of a left front arm 158 and a right front molded hinge cylinder 160 extending from the end of a right front arm 162. In assembly, left front molded hinge cylinder 156 may be seated into a left front lower receptacle 164 disposed on a front case bottom 166. Likewise, right front molded hinge cylinder 160 may be seated into a right front lower receptacle 168 disposed on the front case bottom 166.

A front case top 170 may be formed with two outer surfaces, and may similarly be configured at an angle of approximately 30 degrees to one another, which may provide an outer surface of the front platform 108 and of the front panel 102. The inner surface of the front case top 170 may include a left front upper receptacle 172 which mates, when assembled, with the left front lower receptacle 164, and movably contains the left front molded hinge cylinder 156 forming a left hinge. The inner surface of the front case top 170 may additionally include a right front upper receptacle 174 which mates, when assembled, with the right front lower receptacle 168 and movably contains the right front molded hinge cylinder 160, thus forming a right hinge.

Turning to FIG. 4, a lower right perspective view illustrates additional details of the camera controller platform embodiment 100. The front folding wing 112 and the rear folding wing 114 are shown in a closed position. When rotated to an open position, the front folding wing 112 extends the working surface of the front platform 108. When rotated to the open position, the rear folding wing 114 extends the working surface of the rear platform 110. Although wings 112 and 114 are shown in example embodiment 100 as folding wings, in other embodiments they may be configured to be retractable into the base assembly and/or may be both foldable and retractable.

The front platform 108 and the rear platform 110 may be coupled to the right side panel 118 and on the left side panel 120 such as shown in FIG. 4. The USB cable 127 may be electrically connected to the camera controller platform via the USB port 135, which may be further coupled to an electronics module (not shown). USB cable 127 may be equipped with a plurality of rubber cord clips 176, which may be used for storing USB cable 127, and a protective dust cap 178. The strap anchor 122 may be disposed on the front lower edge of the right side panel 118, and may be used for securing an electronic computing device such as laptop computer 202 (as shown in FIG. 7) into position. A system connection plug 179 that is partially obscured in FIG. 4, which may connect to a system cable 226, may be used to connect the camera controller platform 100 with a pipe inspection system element, such as a cable storage drum assembly 200 (as shown in FIG. 7) and/or with other related components, such as sondes, pipe clearance components, and the like. The system connection plug or connector may also be coupled to the electronics module for interfacing data and information signals to or from the pipe inspection system, such as video or image signals and data, control signals, cable deployment data, etc., with the electronics module, input device, and/or electronic computing device.

A camera controller platform such as platform embodiment 100 may include a capstan or ratcheting assembly to mechanically couple the electronic computing device to the platform. For example, as shown in FIGS. 5 and 6, an enlarged exploded view illustrates details of an embodiment of a capstan assembly 180, which may be coupled to capstan knob 134 as shown in FIG. 2. In one aspect, an adjustable ratchet or capstan assembly 180 may be used to tighten a flexible tensioning element, such as a rubber elastic O-ring band 204 (as shown in FIG. 7), to secure a laptop computer 202 or other electronic computing device to camera controller platform 100.

A toothed bottom plate 181 with a molded central conical frustum 182 may be seated in a central opening in a molded ratchet base 184, the inner surface of which may have a toothed pattern which complements the tooth pattern in the toothed bottom plate 181. A ratchet grip 186 may be coupled to the molded ratchet base 184 with a plurality of screws 188. A pressure spring 190 may be retained in the central opening of the ratchet grip 186 with a bolt 192 and a washer 194. The pressure spring 190 exerts pressure against the molded ratchet base 184, causing the formed teeth on its lower surface to marry with the grooves between the teeth of the toothed bottom plate 181. Rotating the ratchet grip 186 causes the formed teeth on the lower surface of the molded ratchet base 184 to ride up over the teeth of the toothed bottom plate 181, against the force imposed by the pressure spring 190, and thereafter to marry in the next available groove between the teeth of the toothed bottom plate 181. A plurality of oval openings 196 may be disposed on inner surface of the ratchet grip 186, around its central opening. In use, a rubber elastic O-ring band 204 (not shown in FIGS. 5 and 6) may be stretched lengthwise and anchored to the ratchet mechanism by being led through the oval openings 196 and then through its own loop, thus securing it to the ratchet grip 186. The ratchet grip 186 is sealed with a plastic plug 198. The capstan knob 134, as shown in FIGS. 2 as 3, may include the ratchet grip 186 and the plastic plug 198, which cover and retain the other elements of the capstan assembly 180.

The combination of the tooth design and the spring load in the capstan may be configured to limit the torque that the capstan assembly can react to, concomitantly limiting the achievable tension in the O-ring cord (as when stretched across the laptop) to avoid damage to the laptop or other electronic computing device. By appropriate selection of these parameters, the designer can reduce the potential for a user to over-tighten the O-ring cord and damage the laptop secured thereby. In some embodiments, a tensioning mechanism (not shown) may be included to allow a user to select the tension to be applied by the capstan or ratcheting assembly.

FIG. 7 and FIG. 8 illustrate details of an embodiment 700 of a platform coupled pipe inspection system, which may include elements such as a cable storage drum 200 of a pipe inspection system, a camera controller platform, such as platform embodiment 100, an electronic computing device, such as laptop 202, and an interface bus cable, such as USB cable 127, as well as LED status indicators 727. Various elements of the system 700 may be constructed in accordance with details of pipe inspection system and system and apparatus embodiments described in the Pipe Inspection System Applications.

In one aspect, the camera controller platform 100 may be configured to be mounted to a frame 750 of the pipe inspection system, which supports cable storage drum 200. The mounting may be configured to allow the platform to be readily attached and detached, such as through use of pins, bolts, knobs with wing nuts, and the like. The mounting may also be configured to allow the platform to rotate relative to the pipe inspection system to allow a user to adjust the platform and notebook orientation.

FIG. 8 illustrates details 800 of the inspection system embodiment of FIG. 7 in use. The cable storage drum 200 may be used to carry multiple coils of a resilient flexible push-cable 212 (shown partially deployed) whose distal end may be operatively connected to a camera head 208. In operation, a user will pay out the push-cable. For example, by rotating the drum push-cable 212 may be deployed and the attached camera head 208 is then forced down a pipe 210. Excess USB cable 127 may be stowed on the front cord wrap 132 and the rear cord wrap 133 as shown.

The rubber elastic O-ring band 204 may be internally anchored to the ratchet grip 186 (as shown in FIG. 5 and FIG. 6), and may be led over the laptop computer 202 and secured to the strap anchor 122 (as shown in FIG. 1 and FIG. 4). By gripping and rotating the capstan knob 134, the operator may increase or decrease the tension on the rubber elastic O-ring band 204 as the rubber elastic O-ring band 204 is wrapped around the base of the capstan assembly 180 (FIGS. 5 and 6) or released there from. In use, a system cable (not shown) of the pipe inspection system may be connected to the camera controller platform 100 through a system connection plug 179 (as shown in FIG. 4), thereby allowing control of the camera head 208 from the laptop computer 202 or other electronic computing device and/or from the keypad 104 or other input device as needed.

A display screen 206 of the laptop computer 202 or other electronic computing device displays images or video as sensed by the camera head 208, thereby providing a view of the interior of the pipe 210 as seen at the distal end of the push cable 212. Control circuitry in the electronics module of camera controller platform 100 may be used for communicating with the laptop computer 202 and with the camera head 208. Images from the camera head 208 may be captured as individual photos or as video clips, and may be combined and recorded with audio commentary. This may be done by using a software application on the laptop computer 202 or other electronic computing device. The images and video clips may be stored on the laptop computer 202, in the electronics module, and/or on a removable storage device, such as, for example, a USB thumb drive or other memory or data storage device. Images and/or clips may also be formatted into reports to be electronically mailed, printed, delivered by thumb-drive or DVD, or played back for a customer's education from the laptop computer 202.

Turning to FIGS. 9A and 9B, a block diagram illustrates details 900 of electronic signaling elements in a pipe inspection system such as the system illustrated in FIG. 7. A platform system block embodiment 910, which may be implemented in whole or part in an electronics module as described herein, illustrates example detail of circuitry and signal processing in a camera controller platform, such as the camera controller platform 100 shown in FIGS. 1-4 and 7. For example, camera controller platform embodiment 100 may be electrically coupled to interface bus ports, such as one or more USB ports, such as for example, a pair of computer USB ports A 214, and one of a computer USB port B 216 of a USB hub 218 connected with a USB port 135 (as shown in FIG. 4) of the camera controller platform 100, and a USB bus 220.

In use, the USB cable 127 may be connected to the computer USB port B 216 and to the laptop computer 202. Two external USB plugs may allow external USB devices, such as memory thumb-drives or other USB devices, to be connected to each of the computer USB ports A 214. A processing element of the electronics module, which may include, in an exemplary embodiment, a central ARM processor 222, may be configured to control data transmission to, and data receipt from, the USB bus 220 (or other interface bus). The ARM processor 222 may receive communications from an optional ISM-band wireless link 224 or other wireless communications module, such as a WI-FI, Cellular Data, WI-Max, Bluetooth, cellular, or other wireless communications module.

The ARM processor may additionally be configured to receive data link transmissions from a pipe inspection system via an associated system cable 226, which may be connected, in use, to the platform's system connection plug 179 (as shown in FIG. 4). Various aspects and details of system cables and connectors, as well as connections to a cable storage drum or related systems to transfer video information and data are described in, for example, U.S. patent application Ser. No. 12/704,808, filed Feb. 12, 2010, entitled PIPE INSPECTION SYSTEM WITH REPLACEABLE CABLE STORAGE DRUM, and U.S. patent application Ser. No. 10/061,887 (now U.S. Pat. No. 6,958,767), filed Jan. 31, 2002, entitled VIDEO PIPE INSPECTION SYSTEM EMPLOYING NON-ROTATING CABLE STORAGE DRUM, the contents of which are incorporated by reference herein in its entirety.

The ARM processor 222 may exchange control data and information, as well as other signals, data or information, with the camera controller platform input device, such as keypad 104, in addition to the electronic computing device, such as laptop 202. The ARM processor may additionally control the display of a plurality of LED status indicators 227 to provide visual displays of various operating conditions, such as, for example, remaining battery power, power status (e.g., on/off), connection and/or status of attached components such as sondes, microphone(s), sensors, or other input or output devices, and the like.

Still referring to FIGS. 9A and 9B, video and other data from the pipe-inspection system may be provided to the ARM processor 222 by means of a video data link 228, and video may also be passed through a video data link notch filter 229 and a video automatic gain control 230, and be sent to an AV out port 232. Video may alternatively be processed by a video and audio USB decoder 234 such as, for example, the Conexant Systems CX23100, and transmitted by way of USB bus 220 to the laptop computer 202 or other electronic computing device for display.

The camera controller platform may be configured to receive and record audio commentary provided from a user during a pipe-inspection, such as through use of an integral or external microphone or other audio sensor device. Audio, sensed by an onboard or external microphone may be processed through an audio automatic gain control block 236, and may similarly be passed directly to the AV out port 232, or passed through the video and audio USB decoder 234 and back to the laptop computer 202 or other electronic computing device for playback, storage, and/or transmission to other devices or system, such as via a wired or wireless connection.

Data exchanged between the laptop computer 202 and the camera controller platform and any peripheral devices may optionally be encrypted for enhanced security using software and/or hardware encryption devices (not shown) in the electronics module or electronic computing device.

Electrical power for the camera controller platform may be provided by an external 15 VDC power supply 237, which may provide, for example, 15V of direct current through a DC jack 238 on the platform. Alternately, or in addition, power may be provided by a removable battery, such as an 18V lithium-ion battery or other battery module that may be mounted to a battery connector 242. A power supply module, such as a buck converter switching power supply 243, may be used to supply camera voltage and provides 8.5 to 12 volts at approximately 1 amp to power the pipe-inspection system's camera head 208 via a cable and connector, such as system cable 226 and cable connector 179. A separate buck converter switching power supply 244 may be used to modify the supplied power to provide voltages of 0.85V, 1V, 3.3V, and 5V to the pipe-inspection system for other powering functions. Examples of battery pack apparatus and systems as may be used in embodiments of a platform such as platform 100 are described in, for example, U.S. Patent Application Ser. No. 61/501,172, filed Jun. 24, 2011, and U.S. Patent Application Ser. No. 61/521,262, filed Aug. 8, 2011. The content of each of these applications is incorporated by reference herein in its entirety.

Turning to FIGS. 10A and 10B, a data table 1000 illustrates an embodiment of data links for use in communicating data and information in a pipe inspection system, such as system 700 as illustrated in FIG. 7. In one aspect, a tailored data structure may be used to provide messages between a pipe-inspection system, such as pipe inspection system 700 used with a camera controller platform, such as camera controller platform embodiment 100, an electronics module of the cameral controller platform, and an electronic computing device, such as laptop computer 202. Data connection elements and configurations, such as shown in FIGS. 9A and 9B, may be used to send and receive the signaled data. In an exemplary embodiment, the tailored data link may use the following messaging format:

The interpretation of the data stream may be governed by hardware, software, and/or firmware in the camera controller platform 100, such as in the electronics module, and/or by application software installed on, or accessed by, the laptop computer 202 or other electronic computing device. Details of an embodiment of an example data link payload architecture are illustrated in FIGS. 10A and 10B. As shown in FIG. 10A and FIG. 10B, in an exemplary embodiment, the datalink payload may be divided into seven distinct types of data suitable to use in an pipe inspection system. Several of these data types relate to the counting of distance the push cable 212 has been extended into the pipe 210 (as shown in FIG. 8) during pipe inspection. Each data type may include a message ID of one byte, and each message type may include a one-byte checksum after its message content.

For example, count information 246 derived from a sensor built into the pipe inspection cable storage reel may be provided in centimeters and may be converted to feet and inches for local display purposes. Data may be provided from an interface circuit of the cable storage reel or related components, such as via a system cable. Raw count information 248 may include the total number of times the counting unit has been powered on, a stored value for a temporary intermediate zero point, and a current count. A Measurement Origin 250 message may be used to indicate whether present measuring is being done from an absolute start point such as when the system was powered on, or from a relative user-selected zero-point. In some applications the user may also be able to set an absolute zero point, such as the entry point of a pipe, for distance counting as well.

Odometer information 252 may provide a total count of footage extended from and returned into the reel since first activation. Reel information 254 may provides parametric data needed to convert reel rotation into linear distance, including the reel type, the length of total cable carried in the reel, and the cable type. The Raw Total Count information 256 may be a computed value based on the sum of variables under the Raw Count Information 248. Six bytes may be reserved for transmitting a software version 258 used by the counter. Additional fields and data types may be added depending on the application; for example, when sensors are built into the camera head to detect orientation and motion. Count information may be transferred between the various pipe inspection system components including the camera controller platform, electronic computing device, cable reel assembly, and/or external systems. Additional data or information, such as camera orientation, signal levels, and the like may be similarly provided.

Various aspects and details of implementations of apparatus, systems, and methods for providing counting, distance measurement, and related apparatus and functions are described in, for example, U.S. patent application Ser. No. 12/766,742, filed Apr. 23, 2010, entitled PIPE INSPECTION SYSTEM CABLE COUNTER AND OVERLAY MANAGEMENT SYSTEM, U.S. patent application Ser. No. 09/348,517 (now U.S. Pat.

Turning to FIGS. 11A and 11B, details of an embodiment of signal processing of modulated data encoded with video are illustrated. The signal processing illustrated may be implemented in an electronics module which may include one or more processing elements along with related analog, digital, hardware, and/or software components to perform the functionality described herein. Such data may include, for example, information related to camera orientation, signal levels, as well as other data or information, such as sensor data from accelerometer or gyro sensors or other inertial navigation or related sensors, which may be disposed in the camera head. When coupled video and data is received from the system cable 226, such as through cable plug/connector 179, the video and data may be passed to a selective data band pass filter 260 which blocks video signals while passing data. The output data signal may then be amplified by an amplifier circuit 262 and conditioned by an adaptive filter 264. The data may then be detected and parsed by a data slicer 266 and passed to a processing element, such as the ARM processor 222, for further processing and output signal generation.

For transmitted data such as, for example, parametric settings, control data, and the like, the ARM processor 222 may configure and control an oscillator 268, which may then act as a carrier frequency in sending amplitude-shift keyed (ASK) data. ASK data is then passed through a transmit filter 270 and a transmit amplifier 272. A resonator 274 may be used to provide transmission impedance matching for data transmission to the pipe inspection system via, for example, the system cable 226.

FIG. 12 illustrates details of another embodiment of a camera controller platform, in this case in the form of a mini camera controller platform embodiment 1200. Platform embodiment 1200 may include similar components and functionality to that described previously with respect to embodiment 100. For example, platform embodiment 1210, which may include a user interface device, such as user interface panel 1212, may be mounted to a frame 1250 with one or more fasteners, such as screws 1208. Frame 1250 may include one or more legs, such as a pair of front legs 1250a and a pair of back legs 1250b to provide spacing between platform 1210 and the ground or floor surface. Front legs 1250a and/or back legs 1250b may be integrally formed with frame 1250. For example, legs 1250a may extend from the top surface of frame 1250, gradually curving downward and symmetrically. Back legs 1250b may be molded with frame 1250, extending downward symmetrically to form a right angle between legs 1250b and the top surface of frame 1250. A non-skid material 1254, such as textured rubber or other similar material may be disposed on the bottom surface of one or more legs 1250a and 1250b to prevent slippage. Platform 1210 may include one or more LED indicators 1227 to provide information related to parameters such as remaining battery power (e.g., as indicated by color), power on/off status, connection of other components such as sondes, etc., or other data or information.

Such a platform configuration which may be used for line-tracing a pushrod (not shown in FIG. 15).

FIG. 16 illustrates details of an embodiment 1600 of a mini camera controller platform such as platform 1200 with a coupled electronic computing device, in this example in the form or a notebook or laptop computer 1602, where the computer's monitor may be used as a display during pipe inspection operations, such providing video or images from a camera head inserted into the pipe or other cavity.

FIG. 17 illustrates details of an embodiment 1700 of a camera controller platform which may correspond with the camera control platforms described previously herein. As shown in FIG. 17, platform 1700 may include a system cable connector or plug 1720, which may correspond with connector 179 as described previously herein. System cable connector 1720 may be used to provide a connection point to a system cable for interconnecting the platform 1700 with other components of a pipe inspection system, such as a cable drum and/or related components (not shown in FIG. 17). An electronics module 1710 (enclosed within the case shown in FIG. 17), which may correspond with the electronics modules described previously herein, may be incorporated on or within a case of the platform to provide the signal processing and other related functions as described herein.

FIG. 18 illustrates details of a pipe inspection system embodiment 1800 including platform embodiment 1700 as shown in FIG. 17, along with a cable reel assembly 1830 that may be coupled to the platform 1700 using a system cable 1825 as shown, which may be connected to the platform at system cable connector 1720.

In some embodiments of camera controller platforms, wireless connections between the platform and other pipe inspection system components such as the cable reel drum assembly, sondes or associated transmitters, or other components may be used. These connections may be implemented in place of, or in addition to USB or other wired bus connections. For example, in some embodiments, the USB connection may be replaced with a WI-FI or Bluetooth wireless connection, or other wireless connection such as wireless HDMI, etc., which may be implemented with wireless communication circuits or modules included in or coupled to the electronics module of the camera controller platform. Corresponding wireless circuits or modules may be incorporated in the cable drum assembly, such as in associated electronics components.

In some embodiments, video compression and/or decompression may be implemented to reduce the required bandwidth between various communications connections as described previously. For example, video and/or images may be compressed between the cable drum reel assembly and the camera controller platform electronics module and/or between the camera controller platform electronics module and the electronic computing device (e.g., a notebook, laptop, tablet, smart phone, or other computer or other display or computing device), and/or between other systems. Video may be compressed by techniques known or developed in the art such as, for example, H.264, mJPEG, FLASH, wavelet compression, and the like prior to transmitting to the separate electronic computing or display device. Such a wireless mode of communication may be advantageous in that the electronic computing device/display need not be physically attached to the cable reel drum or other pipe inspection system component.

In some embodiments, all or some of the camera controller platform components, such as, for example, are shown in FIG. 7 and FIG. 8, may be integrated onto or within the cable reel frame or inside the reel. In this configuration, these components would rotate with the reel. In such a configuration, an associated battery may be mounted onto the rotating reel and/or connected electrically using slip rings and mounted on a non-rotating section of the reel/drum assembly.

In some embodiments, a camera controller platform may further include a wireless network base station or hub, such as a WI-FI hub, router, or hot spot to serve a live video feed for viewing in a browser on the electronic computing device or another device within the wireless coverage area. The wireless network base station or hub may be included in or coupled to the electronics module of the camera controller platform and/or may be included on another system component, such as the cable drum assembly. The electronic computing device may, for example, host an HTML5 application to provide enhanced features and device controls. Any WI-FI enabled device may then connect to the pipe inspection system and the live video would be streamed in a browser. In other embodiments, device-specific software application may be used. Additional network-related functions may include, for, example, providing a bridge function, such as via a cellular data connection or other communications link to the “Cloud” to allow a user to upload images (snapshots), video, audio, or other data or information to a central server system or other networked system. Network printing functionality may be included to allow the camera control unit to incorporate a printer and/or connect to a network-enabled printer to provide data or information, e.g., measurement parameters, snapshot images, or other information or data as described herein to a network enabled printer. An “auto log” function may be included to locally store data and information and automatically sync to network storage when the user (e.g., a plumber) returns to an office.

In some embodiments, a camera controller platform may further include a module to provide one-to-many streaming data, such as a streaming router or other streaming-capable device. In this configuration, data, such as video signals, images, audio, or other data or information may be sent to multiple users at the same time. For example, during a home pipe inspection operation, a homeowner may be able to simultaneously view video from within their home or yard while a pipe is being inspected, or information may be provided to multiple users during training or demonstrations. Restrictions on the types of information accessible may be included in such as configuration, such as by providing full information to an administrator or primary user, and limited information to guest users or others.

In video display applications it may be desirable to configure the system to minimize video latency with no buffering. For example, the system may be configured to drop frames rather than buffer data to provide an impression of fast responsiveness to a user. Graphical feedback of motion may be provided when dropping video frames. For example, a fake motion blur, a moving arrow, increasing the count, or other mechanisms may be used to provide feedback to an operator to create an impression of responsiveness.

In some embodiments where a wireless hub or hot-spot (such as, for example, a WI-FI hotspot) is included in a camera controller platform, additional functionality, such as hardware and/or software to implement a configuration menu to create customer SSID's may be included. For example, each camera controller platform may be configured to allow a user to create his or her own SSID (e.g., “Joe Plumber's Camera,” etc.).

In some embodiments, the electronic computing device (e.g., notebook or laptop computer, tablet, smart phone, etc.) may be configured to provide additional functionality, such as controlling status and feedback for sondes, lights (e.g., lighting deployed within pipes or other cavities, transmitters, actuators, gas or liquid sensors, additional microphones or other audio or ultrasonic capture devices, and the like. Information such as battery status, memory or storage device (e.g., USB thumb drive, compact flash, SD, or other data storage device) capacity or remaining storage space, component failures or status information, or other parameters may likewise be shared between the electronic computing device and the camera controller platform/electronics module(s).
