It only happens when irs are on i have no ups fitted any ideas??? Thanks in advance guys

Hi guys on site now, just fitted new dvr and no interference can't believe this I have had so much trouble on this site with faulty equipment and equipment not doing what I was told it was capable of. Anyway Thanks for all the advice Stephen.

Sorry dvr is standalone

Excuse my ignorance but what do you mean by true day/night? The cameras are eyeballs 540 line with built in IRs. I will fit a new dvr for testing tomorrow night. Any other ideas. Really appreciate the help.

The power supply is 13.8v 10 amp. The cameras at no more than 15 meters from power supply and dvr. Cable is standard alarm cable doubled up on cores. I have pushed the limits of all these things before and have proved to be capable of much much more in ever respect, that's why I'm so confused as to what's causing this. Thanks

Not a power issue, I installed a 10 amp bench power supply and problem is still the same!!! Wat now aaaaahhhhhh?!?!?!?!! Any ideas guys?

Thanks guys, I was beginning to chase my tail with this job, ill boost ampage and see what result i get. thanks again ill keep you posted
