Your power draw would control how long the UPS runs your DVR/NVR. On Average, a 8-camera DVR would use about 60W, so theortically you should be able to get about 1-1.5 hours or so. This is assuming a 50% power factor / utilization. APC has a calculator on their website to help you decide how large a unit you need.
Sorry, there was a problem. Please try again later.I suggest you to see rating label on your DVR, so you can see their current consumption. Then divide 650W of this back up UPS by your number. Then you may predict 70% of hours from the result.
Sorry, there was a problem. Please try again later.It's advertised as around 90 minutes, but results may vary depending on your power draw. Hope this helps!
Sorry, there was a problem. Please try again later.Your question as presented cannot be answered. You have to measure the actual load of your specific equipment to calculate how long any particular backup battery might last.
