For a few years now I've been installing CCTV systems for small local businesses as a summer job. So far so good, but one of my DVRs that I set up around 5 years ago failed so the owner called me back in to see what I could do about it. Initially I planned on replacing the DVR but he gave me a specific list that he wanted me to adhere to but I'm not sure how I can do so within a budget of £200. The point I'm struggling with is that the customer wants to backup the weekends recordings to watch at home. Keeping in mind that the DVR cannot backup that many hours to DVD and the fact that he doesn't want to install broadband. This made me think more retro in the form of VHS 24hr time lapse which he is happy with but it's not manufactured anymore, so I ask, is there a time lapse DVD recording DVR (is it even possible)? My other plan was to buy those tiny PC's and fit a USB BNC CCTV system which could backup to a USB which he could view at home but I can't find any reliable USB DVR devices, do you guys have any recommendations? Or is there another way that I'm missing completely? Thanks for reading EDIT: Forgot to mention, the system is for a small low turnover firm so 4ch DVR is ample. There are already 4 600TVL cams installed via BNC so that is not an issue. Currently the DVR is connected to TV via SCART but VGA + HDMI is possible.
