Existing wired cameras use 12v Poe
Input through rj45 vs 48v input. I need a splitter that passes through the Ethernet to an rj45 male but also supplies a 5v micro usb output to power Wyze cams
You can buy those on amazon and other places. Search for like “POE tap” or “POE to USB”.
However you must ensure your POE wattage is sufficient to supply both.

There is a plethora of splitters that work off a 48VDC injection which is standard in anticipation of long Ethernet runs. This existing hardwired security camera system covers a four story residential building’uaimg modest runs… I,a,hoping someone has waded through Amazon’s offerings and can help me save time.
Are you thinking something like what @spamoni uses?

I also used this in my setup.
All of which provided what I need to get power to the camera’s and still maintain Ethernet if needed.

First, thank you. What’s different is that I want to run the Wyze cams along side the existing hardwired PoE cameras. Really all I need is a 5v supply with a USB micro plug… It’s not possible to pull new cable (without significant demo)
I’m just gonna wing it with the splitter. I was thrown because there’s no switch. I dunno…I’ll figure it out
I’ll lyk. Thanks again man.

Depending on the age, older stuff is 24V, but they went to 48 not long after.
It isn’t necessarily the voltage that will be an issue but the wattage, each version (POE, POE+, POE++ Type 3, POE++ Type 4) can do different amounts, and also the “compensation” for wiring loss has gotten better with each version too.
Others have provided some suggestions, I haven’t needed to do what you’re doing, I use injectors all the time but just to power access points and the like when the switch isn’t POE. Those are typically just essentially the opposite of what you’re looking for, you shouldn’t need a 2 port switch, just 2 passive ports and a POE filter that redirects it to a built in transformer to drop it down to 5V USB.
I have a much clearer understanding of how the NVR supplies PoE, of the current draw of the wired IP cameras as well as the Wyze cams and even at the low end (15W) there’s room to drive a truck through. Barring of course, resistive connections from poorly crimped connectors and the like. Part of me hopes for and fully expects a gremlin or two. Isn’t that how we learn?
I’ve ordered a couple of the same RJ-45 pass through adapters with the 5V micro USB pigtail that @spamoni recommended as well as 3ft micro USB M-F extension cables for delivery on Monday. I’ll update. Meanwhile, thanks for your insights and your patience.
