Pigtails on 1 power supply always gives problems ..... you only need 1 camera to have a power fault and it’s takes the rest of your system down power supplies are not expensive also distribution box like a 4way would also be a cheaper option Share this post Link to post Share on other sites
Opeth 3 Posted July 12, 2019 So you recommeded not use splitter but the box? Is it ok to have more amper to each channel that the camera needs? Share this post Link to post Share on other sites
tomcctv 187 Posted July 12, 2019 Hi. Yes .... your camera will only draw what it needs ..... under amp power units will run hot power boxes are usually 1.5 / 2amp per output to each cam which is more than enough for your cameras. Also what it does not allow for in camera specs are power surges...... this always happens for a few seconds when your camera goes from day mode to night mode .... moving filters and switching IR on it’s always best to have more power than what you need.

Opeth 3 Posted July 12, 2019 So i need 0.3 amp for 3 cameras that goes 1 amp approx. And 1.25 amp for the motorized camera. So if i get 4 way box 5amp. my 4th camera should be ok? Because im 5 amp / 4 way is at the limit of my 4th camera amp. Share this post Link to post Share on other sites
Benson Chiang 0 Posted July 22, 2019 I think what you're trying to do will work. supply 5 amp / 4 outways spillter = 1.25amp?? This part is correct If it's definitely a 5 amp this PSU will do the job. Share this post Link to post Share on other sites
