cabottaxi 0 Posted May 20, 2015 I have a 4 camera system linked to a hybrid DVR. 3 cameras are full HD SDI. The 4th camera which I am loath to replace as it gave good night vision coverage was rewired with RG59 and moved to another position. I now find that the LEDS no longer work and wondered what can be the issue. It was previously fitted with a 20m plug and play type cable but it was fitted a distance of 25 metres therefore it was rewired to bring it up to date. Can anyone throw any light on the problem.....sorry for the pun. The system is powered up from a 12v 10amp supply. Share this post Link to post Share on other sites
Numb-nuts 1 Posted May 21, 2015 Measure the voltage at each camera and it should be within 10% of 12V. If it isnt then your so called plug n play cables are likely your problem. Share this post Link to post Share on other sites
cabottaxi 0 Posted May 21, 2015 I don't have plug and play cables . The whole system was rewired with RG59. All the exterior connections are housed in waterproof box . Do you reckon it's just down to a poor connection? Share this post Link to post Share on other sites
