geoDVR Gen2 & Gen3 – Multi-Camera Geospatial Digital Video Recorder
Mobile and Rugged Airborne Video Recorder - Automatically Geotag Video from Multiple HD & SD Video Cameras with GPS and FMV Metadata for GIS Mapping Software
The geoDVR™ Gen2 & Gen3 is a Multi-channel High-Definition (HD) and/or Standard Definition (SD) Geospatial Digital Video Recorder platform designed for professional aerial, vehicle and marine environments.
Unlike most mobile DVRs, our rugged mil-spec geoDVR has both "open" and patent-pending methods that log GPS and permanently embed the video with this important location, time and other data.
Connect almost any video cameras or gyro-stabilized gimbals to the geoDVR, and in seconds you are ready to start recording multiple geo-synchronized HD and/or SD video files for playback in GIS (Geospatial Information Systems).
"The geoDVR offers tremendous advantages over our previous video recording system...The in-mission GPS logging and post-flight reporting software means we can provide our client's with vital inspection information in hours, not weeks.”
Video files created by the geoDVR are easy to view and analyze in our LineVision™ suite of mapping applications, including tools
Geo-referenced (GPS) Video
Multi-channel HD/SD Video Recording
Live Video Feed Monitoring
View with Esri ArcGIS, ArcMap & Google Earth
Snap Photos from Video at Points of Interest
Mark Points of Interest with Waypoints
Associate Keywords with Waypoints
HD-SDI, BNC, IP* Inputs
Post-Mission GIS Video Analysis & Reporting
Post-mission, our LineVision video mapping and inspection reporting software provides users with simple but powerful tools for geographic video analysis, editing and project packaging – while leveraging existing corporate Geographic Information Systems (GIS).
The Ethernet ports can be used for our geoDVR RAC (Remote Access Control) software in case someone wants to control the geoDVR via a laptop instead of touchscreen monitor. It can also be used to quickly remove video and other data from the geoDVR with a laptop (Instead of using the removable hard drive or USB ports.) The geoDVR also now supports some Ethernet-based cameras.
The geoDVR records .AVI files (H.264 codec) with permanently embedded GPS data and .MP4 files (H.264 codec). With the optional geoDVR Module for Target Location & MISB FMV and a compatible gimbal, the geoDVR can also record MISB compliant Full Motion Video as .TS files.
The USB ports are used for things like the Remote Start-Stop & Waypoint Trigger, USB connection to a touch screen monitor, connecting a keyboard and mouse for when setting up and configuring the geoDVR. Some customers also use the USB to move the still photos from a gimbal camera and put them on the geoDVR SSD.
The voltage input for the geoDVR Gen2 is variable and can be between 9V-32V DC. The average power consumption should be around 25 Watts. The max/peak power consumption is approximately 65 Watts (though 65 watts is probably way higher than the geoDVR will ever require).
The geoDVR Gen2 is usually shipped setup to start on ignition (basically, when the IGN input gets voltage (between 9-32V) for more than a couple of seconds, the geoDVR powers on). The common way most customers wire this is to put a on/off switch between the positive terminal and IGN terminal. This way, once the switch is turned on, the geoDVR will start.
IMPORTANT: If using the wall power adapter for testing do not use 220V (European, other standard for AC) directly - it will fry the unit. What you'll need is a 110V converter. Once converted down to 110V AC, the power supplies we provided will then convert the voltages to do 12V DC which is the voltage the geoDVR requires.
The geoDVR has proven to be one of the most reliable commercial geospatial video recorders available and when properly configured and powered should provide you with dependable recording. However, the geoDVR does offer several ways to insure it is successfully recording video during flight (or not):
With a Monitor Connected
If using a monitor connected to the geoDVR there is a status indicator bar at the bottom of the primary geoDVR interface. In the status indicator bar is a section called "Is Recording." These square icons indicate the recording status of each of the video channels going to the geoDVR:
Green squares indicates video IS successfully being recorded - All is good, but monitor status occasionally.
Red squares indicates NO video is being recorded - If this occurs while recording, investigate cause of issue as soon as possible.
Yellow squares indicates a potential issue or warning state such as lost GPS, and can proceed a Red square - If this occurs while recording, investigate cause of issue as soon as possible.
With this capability the geoDVR is constantly checking to make sure fields are being written to the geoDVR in real time.
Also there is the System Output Status Panel. This panel displays a variety of system status such as the live status of the GPS connection, user actions and system errors (if encountered).
You can see an example of the geoDVR successfully recording 3 channels of geospatial video in flight in this video:With Audio Connected
Using the communications systems adapter for aircraft audio, or even just a simple speaker or ear bud for the observer, the geoDVR will provide audio warnings when it detects video is not being recorded.
The geoDVR typically runs independently of the leak detection system. There are NO proprietary technology integrations or specialized post-processing services required! After the flight, the LDS operator and analysts simply import the data into our LineVision post-inspection reporting software for analysis and deliverable creation. We can modify LineVision to support data directly from most LDS manufacturers. We have worked with data from the Boreal Laser and Pergam LDS systems can usually add support for other systems as well. Please let us know if you have some other specific direct integration requirements, it's likely our professional service group could help devise a solution.
The amount of video you can record depends on the bitrate of the video. This can vary depending on many factors:
Scenery (A complex scene of a city with many different colors can be compressed less than a pure blue sky for example)
Encoding quality (default is 'High' on the geoDVR)
Resolution, Framerate, and Color Depth
Number of channels you are recording
Codec (geoDVR uses H.264)
For a single HD 1080P30 channel on 'High' quality setting (the default in geoDVR) using the bullet cams we include in our geoDVR kits, we estimate the bitrate to be around 15mbps - or 37 hours of footage for a 250GB drive. Keep in mind this figure can vary significantly depending on the specific footage you are recording. To get a more accurate figure, we recommend recording your own sample footage to calculate the average bitrate with and extrapolating from there.
