Providing dc power to cctv security camera system

Question:


Hi

I am installing 6 ip cameras around the outside of the house. Im running cat 6 cable back to the centre of the house and then dropping the cables into a cupboard where my switch and router is.

I am confused about how to handle the DC power to all the cameras. I was under the impression it was go out and get a dc extension cable, connect it to the appropriate adapter and off you go.

My intention was to run all the dc power back to the same cupboard and then connect to some sort of multi adapter.

Could you please tell me how I should do this as I am rapidly losing confidence:-)

Answer:

Hi,

Yes you are on the right track. Your cat6 wire can come back to a central location and be connected to a central power supply.

You just need to make sure that you get a power supply that can handle the amount of power you need.

Basically you need to add up the total number of amps that your cameras will draw and make sure your power supply has enough total amps for it. Ideally you want to only max out your power supply at about 80% to make sure there is no chance of any of your cameras losing power.

If you have infrared led's on the cameras then you will want to add up the total amps based on the infrared being activated vs not activated.
