newguy123 0 Posted February 29, 2012 Hello, ill start by saying im very new to cctv so please bare with me. I installed a CCTV system with 5 cameras. Each Cameras RG6U length is about 800 to 1000 ft. when finished final hook up of the DVR I noticed my pictures arnt very hot at all nothing that was showing up on my little monitor. I read that i may require a amplifier is this true? if so does it go on the camera end or the DVR end? I was thinking about the middle but I rather not have a splice. I would highly appreciate any help at all!! Thank You Very Much. Share this post Link to post Share on other sites
jeromephone 6 Posted March 1, 2012 I think you may have another problem you should see picture over rg6 at that distance. What kind of monitor are you using. Make sure you have the correct inputs. Take a short cable and take the monitor to the camera and see if you get a picture. You want to make sure the camera is putting out a signal Share this post Link to post Share on other sites
newguy123 0 Posted March 1, 2012 when i use a monitor at a short distance i get a perfect picture when i attach it to my long run of cable its fuzzes up about 30 to 40%. oh and i took the full sized monitor and hooked it to the camera with a 12 ft rg6 patch cord perfect picture. thanks btw i appreciate any help at all.

Soundy 1 Posted March 1, 2012 800-1000' is pushing it a bit for coax, especially if they're cheap cameras. You may need to go to UTP with baluns. Share this post Link to post Share on other sites

You may need to go to UTP with baluns. ^^^ This, my analog system only recommends up to 180' on coax, 300-400' UTP cat5, 1200' SSTP cat5. Careful on an amp, dont cook the dvr Share this post Link to post Share on other sites
jeromephone 6 Posted March 1, 2012 maybe cat 5/6 baluns with one end and active ie powered ? Share this post Link to post Share on other sites

You may need to go to UTP with baluns. u saying that cheap camera do not produce 1 volt peak to peak ? should rephrase I guess Why do u think "cheap" camera can't push video far ?

newguy123 0 Posted March 2, 2012 hey guys thanks for all the help. the camera im using is http://www.smartvisiondirect.com/index.php?ca_id=221&it_id=1150&query=item it seems to being putting out Frequency Horizontal : 15.734KHz / Vertical : 59.94Hz (NTSC) Horizontal : 15.625KHz / Vertical : 50.00Hz (PAL) S/N (Y signal) More than 52 dB (AGC off) Video Output CVBS : 1.0Vp-p / 75ohm do you think an 8 Ch cat 5/e ballu'ns will work it says it rated for 1000ft will the picture come out good? my next step is to buy that ballum and take a box of cat 5 hook both end to the ballun's and see if it works i'd love more insight thought thanks alot guys!!

I'm saying they may not handle the extra loading very well. Share this post Link to post Share on other sites
