GrouchoBoucho 0 Posted October 16, 2012 depends on the quality of the cable. proper rg59 or rg6 is usually good for a 200m or more. Share this post Link to post Share on other sites
Dipol_CCTV 0 Posted October 16, 2012 30m is nothing for video transmission over coax. Triset coax cable can reach 600m or more - Ive checked myself. If it is an IP camera, then You apply the same rules that You do in LAN - 100m for UTP. Share this post Link to post Share on other sites
ssnapier 0 Posted October 16, 2012 Did you terminate the cable yourself or did you buy it pre-fab? Share this post Link to post Share on other sites
shockwave199 0 Posted October 16, 2012 First off be sure of the length you really need. Sometimes you think it's less than you actually need. But generally, get an appropriate length cable. If it's a pre-made type, get a shorter one. If you're putting the connectors on yourself, cut the cable to the right length. You have quite a lot more cable than you need. You can be lazy and use it, or you can get an appropriate length. Better habits improve results overall. Share this post Link to post Share on other sites
Numb-nuts 1 Posted October 20, 2012 30m is nothing whatsoever you should be safe. Obviously there are all sorts of other issues but if you used a compatible 75 ohm cable or UTP and suitable baluns, 30m is well withing the distances acceptable. The video signal at the camera has a 1volt amplitude peak to peak and thereis always a sinal loss. Upto 6db is acceptable then it's time to get the signal corrected using a VLC video line corrector. A scope or some other peek measurement device will be needed as this cannot be done correctly without measurement. Share this post Link to post Share on other sites
