Thomas2013,
Other options might include:
- sending snapshots (from events such as tripwire, MD, or external PIR sensors hooked to cameras). Text or email.
- Using SD card in camera, assuming they can't reach/steal the camera. Redundant storage. I suggest that for license plate info, useful if NVR stolen.
- Installing a "decoy" NVR. The real NVR might not be stolen.
- Backup to cloud, sure. May be expensive. Alternatively, send video to an ftp site off-premises
Check this forum for posts by fenderman and nayr. They recently discussed this very topic, in a thread that was an NVR/BI pro & con comparison. That's a bigger topic, but backup of data was touched upon.
Another approach is to make it difficult for the thieves to have the time to search for the NVR. Sirens & strobe lights. Flashing lights outside the house. I even used a sound generation pcb from Adafruit ($20) that will play pre-recorded clips, such as "you're being recorded", "video stored off-site", 'Police on the way", etc.
ie: deterence. Instead of relying on video footage to identify the thieves, through their hoodie, cap. I use a laser line across the only way to drive onto my property. I get the email, w/ snapshot. I can surf in to view live. I can listen to what's going on. When I call 911, I have info on a "burglary in progress". I wanna stop them before they enter the house (and look for the NVR).
Good luck,
