sk78 0 Posted July 11, 2015 Hi, I was just wondering if anyone can help me identify a suitable independent power supply that i can connect a DVR and at least 1 camera to. The DVR will require 12v 3Amp Power and the camera 12V 1Amp and will be used for a maximum period of up to 1 hour. The reason i said independent power supply is because we don't want to connect to the vehicle's battery. We want to use this setup so we can record diferent day and night footage with about 5 different cameras. A client has asked to compile footage of each camera in order to demonstrate the picture quality of cameras they sell. Any help would be greatly appreciated. Thanks Sam Share this post Link to post Share on other sites

Thanks Sam You need a dual battery system. You can run your cameras and NVR off the second battery but still charge it all from the vehicle's charging system. You can buy them on ebay. If you get a 40Ah Deep Cycle Battery you can run it for two hours and still only be at 20% depth of discharge. That is good for battery life. Share this post Link to post Share on other sites
