When arriving on the scene and finding a DVR, your main task will be to get usable video evidence from the device.  But what is the best way to do this?  There are a few ways to export video from a DVR, and each can be a viable path to your evidence.  Each method has its strengths.

Your best evidence is the video stored in the format the DVR originally recorded on its internal hard drive.  DVR Examiner gives you the ability to extract original video from the DVR’s internal hard drive directly, bypassing any passwords, working in a forensically sound manner, and making an easily searchable list of videos. However, you will need to power off the DVR to access the hard drive.  Best of all, we don’t re-compress the video, so what was originally on the hard drive is what you will get from DVR Examiner!

Many DVRs give you the ability to export video to an external storage device.  This is great, if you know the password to the device, can operate the menus, and get a quick export.  If the DVR is already running, and you are worried about the hard drive not turning on again, performing an export from the DVR may be your only option.  Unfortunately, often this process is slow, results in lower quality videos, and can be infuriating with lost passwords and finicky with storage medium.

If none of these options are available to you, you may have to record the video out from the DVR itself.  To make this option work, you will need to have a capture card with you in your tool kit, along with a large and fast hard drive.  Overlays, like timestamps, may obscure important actions or details that are recorded however, most DVRs will playback video at the correct framerate, giving you important timing information.  At least some evidence is better than no evidence.
