Cat-5 UTP passive balun system surveillance camera …?
I did some research on video surveillance systems - Standalone DVR cameras and CCTV - and found something that is not fully understood. I am looking into the use of "passive baluns" to connect each camera to the DVR. Now, descriptions of each list, I read says something along the lines of "Passive device - no power needed." Is this it simply means that the BALUN in itself does not need a power supply, or that the use of baluns device photo does not need an external power source? It would be surprising if the case were true, as my company is looking a camera system 16, and we run somewhere around 4000 feet of cable. It would be nice if we could run a CAT-5 cable from each camera to Instead of a video cable to the DVR and a power cord a reserved table of food. Suggestions?

The Balun passive means you can transmit video signal via a CAT5 cable. The advantage is that it can transmit video over a cable longer term, usually up to 300m using passive balun. Normal coaxial cables have a limit approximately 90m. The twisted pairs in CAT5 cable is also good to reject interferrence electro. No need for power "or" passive "has not require a power amplifier or other power source to extend ..... SINGLE VIDEO SIGNAL until 300m. Active Balun is a Powered balun sense that amplify the video signal up to about 1200. If you use a CAT5 cable to carry power to the cameras, the balun will not difference in distance that can feed on energy. After 60 meters of cable tension in most cables are beginning to fall. If you want a long cable length, to power the device, use a power supply 14V or 12V to 28V PSU cameras to 24 cameras. In this case, the voltage drop on the cable distance will be slightly offset by the voltage that produces the greatest. Here are some tips ------------------------ 1) Use a balun with a power connector with a single device is necessary or make the video and the power connection on the side of the camera, For example, see the DC connector balun here http://www.cop-security-online.co.uk/acatalog/Shop__front_Passive_system_36.html 2) Something that I made in a factory with the unit Long-range photo, use a 24VAC power converter then use a 12V DC 24VAC guarantee could get 12v at the end of the room up to 250 meters I hope this help.
