Need to place a WiFi AP as well as an IP camera (different locations); both devices are not near any power outlet. Is PoE (non standard*) a solution for such cases? From what I have seen on web sites, these contraptions have two units, one near the switch to inject the DC voltage + the LAN pairs and the second near the device end to tap out the DC and separate the LAN pairs. I am not sure if 12VDC/1A (the input power requirement for AP and camera) is sustainable over the CAT5 pairs.
POE is 48v. Unless the endpoints have an internal switcher, you will fry everything.
Thanks but I am aware of it that is why I did put the (*) and the reference to asterisk as shown below in my OP.
- not the 48V as per 802.3af Standard.
The DLINK unit I posted does inject 48V at origin; the destination unit has a switcher for 12V/5V output - I guess it has been specifically designed to "remote" power thingamajigs like WiFi routers/APs, IP cameras and such.
