So I have a camera and a siren, both are driven by a PoE connection. I have a PoE switch, but it only can provide enough power to drive the siren. So what I want to do is hook both the camera and siren into the PoE switch, but run the connection to the camera through a PoE injector so it gets enough power. In this way I can run the camera and the siren with 1 PoE switch and 1 PoE injector rather than 2 PoE injectors and 1 unpowered switch.
Will I blow up my PoE injector if I use an already powered ethernet connection as the data input connection to the camera's PoE injector? This seems like a pretty unusual set up so I just figured I wanted to ask before I try it out and potentially fry my PoE injector.
Okay just looked it up and both the PoE switch is 802.3af compliant and the injector is 802.3at compliant so I'm going to give it a try. Thanks! – Adam O. – 2018-02-16T18:56:03.573
