A friend of mine owns a small coffee shop and is looking at putting in a security camera. I have a series 1 and a series 2 TIVO boxes sitting with bad hard drives. My question is would it be possible to replace the hard drive with an image and use it as a DVR on the camera. I would think it would be possible, but just not sure. I have a 120 gb hard drive not being used that I could put in, and since I have everything it seems like the cheap way to do this. Dedicated surveillance DVRs and the time lapse VCRs arent the cheapest things. Thanks for help.
