The geoDVR Gen2/3 hardware 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 for years to come. 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:
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.
