Well, at first it seems a simple matter to solve but from what we received from our forum members’ doubts it is not simple to solve or choose which source to use to link multiple security cameras, let’s cover a bit of that subject below with tips you can Help solve your problem.
How to Connect Multiple Security Cameras to a Source
The simple electric scheme is a parallel connection where each camera has its (+) and (-) ex polarity.For alloy 12 cameras it will all be the same as it is positive with positive and negative with negative but for that connection to work it will depend on the current of the source that we can set adding the current of all the security cameras that will be connected to the source .
Ex. Let’s continue with the ex.12 cameras, each camera has a current of 450 mA let’s sum this electric current 12 times because it is the number of cameras that we want to connect, soon we will reach the total that is equal to 5.4 A of current, this way it will be A source of at least 6A of electrical current is required. In this way we can say that the parallel connection will work for sure.
This calculation helps you when choosing which source to use to connect multiple security cameras, another factor that we have to take into consideration is the distance that this source will get from the security cameras if it is to be far away we have to think and calculate a supposed fall Voltage and current.
