heaton231 0 Posted February 15, 2017 [bETTER THAN 1280TVL] KARE® 4CH CCTV DVR System & 2x HD Megapixel Indoor / Outdoor Security Bullet Cameras (1280x720 Pixels, Quick Access Over iOS / Android, H.264 Compression, 36pcs LED for Night Vision, Email Alerts & Motion Detection, IP68 Waterproof and Vandal-Proof Housing, Black). Hi Guys, I purchased the above from amazon, I'm a spark by trade so don't do this usually. This is being used in a block of flats. The cable runs are around 100m and I'm using 2 cameras. I'm using the pre-made cables which are joined (sorry). When I boot the DVR pictures are great but after a couple of minutes the pictures start to degrade and then disappear completely. If I reboot, they come back but then pop off again. I've changed both the DVR and PSU and still the same. I'm pretty sure I'm going to be told the cable is pants but are there any tests I can do to make sure? Many many many thanks for any help!!! Paul Share this post Link to post Share on other sites
Galveston 0 Posted February 15, 2017 Two of my cameras run that far, but with old better quality cable, but I am noticing that my cheap computer is objecting to all these cameras, on my other computer it is much better, are you using a monitor? Share this post Link to post Share on other sites
heaton231 0 Posted February 15, 2017 Hi, yes I am but it's not the monitor. The cameras are dropping! Share this post Link to post Share on other sites

Go with cat5 with baluns ..... 1 pair for video and the rest split for power Share this post Link to post Share on other sites
heaton231 0 Posted February 15, 2017 Thanks for that, I have some drums of shotgun cable. Would that be OK as an alternative? Cheers. Paul. Share this post Link to post Share on other sites

Yes you are good with shotgun.... you will also see a little improvement with coax as that is 75ohm unlike the cable kits you are using now. Also the power conductors are too small and not allowing the amps your cameras need Share this post Link to post Share on other sites
heaton231 0 Posted February 15, 2017 Hi, thanks for that. My butt is on the line so I need to get it sorted. It's strange because the images are really good for a few minutes and then gone. Do you think it's the voltage getting through to the camera that's the problem? Many thanks. Paul. Share this post Link to post Share on other sites
