ninja_warrior 0 Posted August 11, 2016 Hi, I set up my cctv system many years ago and finally the DVR had packed up so I brought a replacement and switched it over. All seemed well until I played back some of the recordings, daytime's perfect but I can't see a thing during night. This wasn't the case with the last box, looking over the description of the item I bought there is no mention off night vision :/ I know my cameras are fine as it was working in the past, all I've done is switch the box. Has anyone had a fault like this before? I've spent hours trying to sort it, scouring the internet with no luck. Any help/insight would be most appreciated.

the toss 0 Posted August 12, 2016 The "box" aka DVR has nothing to do with lack of night vision. If they worked before and you haven't changed the power supply then they will work now. I bet you have ONE power supply running both the DVR AND the cameras. You have put in the new Power supply that came with your new "box" and it cannot run the IR at night. If this is the case then use your old power supply for the cameras and the new one for the DVR Share this post Link to post Share on other sites

That's exactly what I was thinking as the cameras have IR built in and the only thing that has been changed in the setup is the DVR. To answer your question, no, I have 2 separate power supplies for the DVR and cameras. The old DVR ran off 19V power though and this new DVR is 12V. Also the cameras run off a 4 way splitter but this has always been the case. I may try setting up an extra light of some sort to help during the night.

jeromephone 6 Posted August 13, 2016 try a seperate power supply on one camera and see if the IRs work I would also check the power at the cameras to see if you are getting adaquate voltage to power the IRs Share this post Link to post Share on other sites
