I Need A High Quality CCTV PTC LED Power Distribution Unit

Recommended Posts

I'm getting prepared to install a 16 camera security system this Spring. I'll be using Q-See QCA7207B 720p HD IR cameras. Yes, I know it's a low end system. I'll upgrade in the near future. I'm also pulling Cat6a cables for each camera in the event I need them in the future. I'm looking for a PTC box that also has LEDs for each channel.

 

I don't understand the amperage requirements. Some of the PDUs have 10 amps while others have 12, 15, 20, 24, 29, 30, etc, etc, etc. I'm not an installer or an electrician so I don't understand how a 10 amp PDU can provide enough amperage for 16 cameras that may require 2 amps each. Some offer a maximum of .5 amps per channel while others offer 1, 1.6, 1.8, 2, 3, etc, etc, etc. I don't want to get a PDU that provides 3 amps per channel if it's going to fry my cameras. Do these CCTV cameras have over amperage protection built into them? Do some of these PDUs offer X amount of amps per channel but only provide what the camera needs if it's less than X amps per channel, such as high quality cell phone chargers do?

 

I've spent quite some time researching these PDUs but I would appreciate it very much if those in the know could push me in the right direction. If there is no real advantage to using a PTC box for residential use then that would give me more options as I could also choose a fused box. I prefer a PDU that can be locked. I would also prefer a box that allows access for the wires from the back of the box so that there are no visible power wires. I would rather pay $200, if necessary, rather than $50, to get a high quality PDU. I have looked at the following:

Thank you in advance for your time and any assistance provided. I appreciate it very much.

The Q-See QCA7207B camera requires only 0.2A max.

 

16 cameras x 0.2A = 3.2A Total

 

A power supply with 4.0A capacity or larger rating is ok...

That's good to know, myiicu. Thank you again for your assistance. I certainly appreciate it. I should be OK with a 10 amp power supply. I simply don't understand the operation of the power supply and amps in general, or volts and watts for that matter.
