Hi.
I have installed a new door entry system keypad and camera. The problem is that I am experiencing a voltage drop over the distance of the cable that is making the camera not power on correctly, ringer and voice work fine.
My current wiring is using 4 cores of what i presume is 0.5mm2 6 core alarm wire. (this was in place for my old camera)
Questions are....
1. This may be daft (or may not be) can i double up the wires i.e use the 2 unused cores to power the camera on the keypad? I presume the camera power comes from via the red and blue wires? so If i use the spare orange/white and blue/white and join them to orange and blue at the monitor and then into the same couplings at the back of the camera/keypad, will this reduce voltage drop?
2. If 1 isnt advisable. Then it appears that I may need thicker cable. Id say at a guess the cable run is approx 25M. Id rather be over than under in terms of cable thickness, what cable thickness would be advisable? The output at the monitor is 14.7V
Thanks In advance
