1.7 No Power Outlet—POE (Power Over Ethernet)
The TriVision NC-250PW HD 1080P PRO is a very flexible network camera which works with PoE (power over
Ethernet) devices that comply with the most common industry standard, known as IEEE 802.3af.
You have 2 ways in which you can power the camera: with the included 12 V power supply, or you can use
PoE instead of the AC adapter. If you use PoE, the included 12 V power supply would not be used at all. Now,
there are also 2 ways to provide PoE power to the camera: You can use a PoE injector, such as the one from
TP-LINK TL-PoE150S or you can use a PoE network switch such as the Netgear GS108PE. Either way, powering
the camera with PoE allows a cable length of up to 300 ft. This allows the camera to be placed in areas that
aren't close to a power outlet and with weak /without Wi-Fi signal strength
Note:
One thing to keep in mind about the choice of a PoE injector vs switch: If you use a PoE injector, you
can still use the camera with wired or wireless networking. However, if you use a network switch, the camera
will assume you want to use wired networking and will shut down the wireless adapter in the camera. So you
would only use a network switch if you intend to connect the switch to your router for a completely wired
(not wireless) networking setup. But the advantage of a PoE switch is that they can usually power multiple
cameras, while PoE injectors tend to be for one device only
