electric power question re PoE security cameras

[The Original Ralph]

i'm not that literate in electrics, but keep seeing vague references in various product descriptions that give the impression that if a device, like an outdoor security camera is described as "PoE", that it doesn't need a power splitter at the camera, i assume that if that's the case, the camera has the circuitry to manage the power coming from the PoE switch / hub.

Is this correct?

tks in advance

Power over Ethernet. Exactly what it says.

The camera gets its power from a properly supplied ethernet cable, as well as transferring the video signal.
A suitable switch, router, or camera DVR can do this.

I have a 4 camera + DVR system like this.

tks., but my question was and is, if a device is described, by the product's mfgr, as "PoE" do i still need a power splitter at the camera or devices' end, or does the device have the circuitry to control the current coming in.

Apparently the voltage traveling over the ethernet cable is 48V and obviously needs to be brought down to 12V or 5V (whaterever the device is rated for)

Here is a PoE capable switch:

8 ports, 4 of which are PoE.

At the other end would be a PoE capable camera.
In between, a standard Cat5e. No splitter needed on either end..

THANKS - "No splitter needed on either end"

that's the answer i was looking for
