Help with video power balun

Recommended Posts

Im planing to install a 4 cctv system to a house. Each camerahas power 6,6w. Im using 12vdc 5 amp power supply. My problem is with my balun and if the baluns i have can transmit without any problem power to camera for how long? 100m? 200m?. Not video. Power.

I will attached a photo of package of balun and i waiting your answers.

The distance the power travels through your baluns will depend on a few things. One is the power requirements of the cameras which will be 12v and 0.55amp based on the information you have provided. The other is the thickness of the cable you will be using to transmit the power as a thinner cable will lead to more volt drop over the run of the cable. The packaging on the baluns provides some information on this for you. E.g if you want to run a 12v, 0.5amp camera (yours have a slightly higher amp requirement) over 24 AWG cable for 100m your power supply will need to be outputting 15.5 volts as over the length of the run it will drop to the 12 volts your camera requires.

 

The general rule is the longer the run the less voltage you get at the camera end and you have to compensate for this by providing more volts at the power supply end.

On my first picture there are 2 kinds of balun. If i use the second one with 24v power supply will be ok? Because it say from 24-36v the balun can convert to 12vdc. Is there a possibility to burnt my camera?

And on the balun that i pictured if i use 23 awg with power supply 12v will cover the slight different of voltage?

Thank you
