So you are in the beginning stages of planning your CCTV system yea? Or do you have all your equipment and you are starting to doubt if you have the right equipment to make for a good installation? Either situation is a great point to start to think if you are on point with your cable runs for your security cameras. If you are smart, you would have RG59 cable that also has an 18x2 power set in the same jacket. Having this will ensure that you don't over work yourself in running cable, as this is a strenuous part of installing your cameras. Actually if you have the right tools, it should not be too difficult, however, we are talking about cable distances in this post. If you have RG59 cable know that at about 500 feet you have reached the max capacity on video signal strength. Five-hundred feet is the longest run you can have for video. Now for power to a camera you are looking at about 1000 feet. Video signal is very weak, that is why the BNC connection and connector was invented, however, you can solve the distance issues by using video baluns and video balun transceivers. Video baluns re-strengthen video signal and give it the boost you need to go up to 1500 feet in most parts. There has been reported distances with certain video baluns that transmit up to 5000 feet! Video baluns also solve the power issue too! If are trying to figure out how far you can run power for a 12-Volt DC camera, power-over-ethernet will work better for you if need to go past 500 feet or more. Typically we've seen 500 feet be the max capacity for video and a 1000 feet for power to your security cameras. If you are in this problem, we have a simple solution for you, try video baluns to get into the range you need. If you have multiple cameras you will need a POE switch to run your camera into a network. POE switch just means power over ethernet! Just make sure you have the necessary bandwidth to stream network cameras.
