inglishg Posted February 10, 2019 Share Posted February 10, 2019 I don't often get involved with CCTV, but have been asked fire help with a guys newly installed system. It's a Sannce DVR with two analogue 1080p HIK vision cameras. The cables are pre- made (two different "makes"), and the cameras and DVR have separate power supplies. The cables run through the house wall and then in different directions to the two cameras. There is minimal excess cable coiled up and they don't run next to power supplies. Both images are show interference - the colours are distorted. Is there something obvious? Cheers Quote Link to comment Share on other sites More sharing options...

satsuma01 Posted February 10, 2019 Share Posted February 10, 2019 The image won't load properly but sounds the cables that are pre made are causing image loss someplace the video coax with a rg59 cable or a cat5 or 6 with a decent balun at each end of the run pre made cables are not much good from what I've found with them Quote "If you carry your childhood with you, you never become old.

inglishg Posted February 10, 2019 Author Share Posted February 10, 2019 Thanks for the reply. Obviously my knowledge is inferior to yours, but a relative has a similar set up, and there's is crystal clear - same cameras and DVR. I presumed there's something interfering with the signal somewhere? I understood HIK vision cameras were ok? Cannot really respond about Sannce. Maybe I should suggest he changes his DVR? May prove if the issue is the cameras/cables or DVR itself... Cheers Quote Link to comment Share on other sites More sharing options...
inglishg Posted February 10, 2019 Author Share Posted February 10, 2019 Thanks for the reply, much appreciated. Ok, I'll wire another camera into it, and see how the image is, before getting the ladders out... If I can prove a good image with a replacement cable, then it could be happy days :-) Perhaps I'll be sticking to my 30 years in security systems rather than poking my nose into the magic of CCTV! Thanks again for your help. Quote Link to comment Share on other sites More sharing options...
al-yeti Posted February 10, 2019 Share Posted February 10, 2019 Could be the camera PSU tho Quote Link to comment Share on other sites More sharing options...

Cheers Not that inferior lol But you could take a cat5 to the camera for the video with some baluns to see if it makes a difference if it doesn't might be PSU issue or something else Quote Link to comment Share on other sites More sharing options...

satsuma01 Posted February 10, 2019 Share Posted February 10, 2019 I'd say try a new cable first on cat 5 with Balinese and power run through that also whole the camera is powered check the voltage at the camera end it should be around 13 ISH volts if DC 12 adaptor Quote "If you carry your childhood with you, you never become old.
