unit979 0 Posted December 20, 2006 Ok, I just installed a 10ct 320 dvr (Kalatel) in a bar. He wanted to keep the outside cameras (front & back) that I have going to 2 seperate monitors that he had from his old system. The 8 of my cameras are working excellent. His old system was a Wal-Mart style with the cat5 going into the back of the monitors that processed 4 cameras. What I have done was I used one monitor/camera that he already had for the front and the same for the back, so he could easily see people entering & leaving. It looks good on the 2 monitors. The problem I have is when I used the rca (video) and adapted it to coax to run it to the dvr, the pictures are messed up. It has wavy lines that run up the monitor (main monitor for all cameras), kind of like a tracking problem on a VHS tape. It is about a 50' run from his old monitors to the dvr location & main monitor. I even tried running a 50' rca cable with a adapter to bnc & it did the same thing. WHAT IS GOING ON!!! I also install dish network, and have came across a couple of boosters from the cable company. But this being my first main install, I don't know if these type of boosters can be used, or if it would fry the system. Please anyone help if they can. The bar owner is getting a little upset, since the install was done a while back, & I still don't have this resolved. Also, I cant get rest of payment until this is resolved. Thanks in advanced!!! BTW, I AM A NEWBIE!!! Brad Wright (765)251-1110 Share this post Link to post Share on other sites
rory 0 Posted December 21, 2006 If those 2 Monitors/Cameras are getting powered elsewhere, then this could be a ground loop. Run an extension cord to the main DVR location and plug them all into the same outlet. See if the problem still exists. Share this post Link to post Share on other sites
unit979 0 Posted December 21, 2006 Thanks, I'll try it first thing tomorrow. Brad Share this post Link to post Share on other sites
rory 0 Posted December 22, 2006 Also make sure the cable is not running over any high voltage like lighting etc ... Share this post Link to post Share on other sites

I ran the extension cord over and works perfectly. It's nice to know people can count on you and this site for help. Thanks again!!! Brad Share this post Link to post Share on other sites
rory 0 Posted December 23, 2006 Cool gonna try a Ground Loop Isolator or leave the extension cord for now? Pelco has a Ground Loop Isolator .. if you are looking for one. http://www.pelco.com/products/default.aspx?id=230 Or you could optionally go the UTP/Cat5 route with NVT as their receivers have Ground Loop Isolation built in, but have to choose the right one. www.NVT.com Rory Share this post Link to post Share on other sites
