PoE Cameras vs. DC powered

post #1 of 5
Thread Starter 
I wired x 2 Cat5e to my security camera locations. I'm now deciding if I should use PoE cameras (ie. Axis M3114-Ve) or a standard DC powered camera. It seems to me the PoE camera would be the way to go as I'd need a PoE switch for both types of cameras, but the non-PoE camera would need a splitter to power it through the ethernet connection. So why would anyone pick a DC camera over PoE?

If you have 2 cat5 you can use the wires in the other cat5 to carry DC power. I use a single cheap brick style 12V dc supply to power 4 cameras.

Is there any advantage to that though? Either I use a PoE switch from the wiring closet, or I'd have to have an injector and a splitter closer to the camera to power the camera. Unless I'm missing something it seems a single cable with PoE is better.

Well all my cameras are within around 75ft of the central location and attached at that point to the DC power supply and they work fine. Advantage is cost primarily by not having to buy a PoE switch and/or camera and instead using cheaper DC power supply(ies). If the camera has a DC input you use the wires from the spare cat5 to feed it dc (or attach a barrel connector if necessary). On the other end you attach the wires of the spare cat5 to the DC out of the power supply. Splitter/injector would only be required if you only had 1 cat5 (and maybe not even then as you can steal half the wires from the cat5 in a 100Mbit line and use them for DC) or if the camera did not support DC input (even in this case you could probably figure out how to feed it DC on the PoE pins, unless it is Gigabit).

You could also consider the ubiquiti cameras that come with individual POE injectors for $70-100.

I second the idea of using the second CAT cable for power. POE switches cost a lot more than simple switches.
