I want to add a mic onto a POE PTZ camera. The camera says 24v but the POE splitters say 48v. Will the 48v work or do I need to find a 24v one?
Microphone ?

Your camera likely has tow powering methods, only one can be used at a time. Either POE or 24v input connector.
POE (power over Ethernet) runs between 48-56v. You won't be tapping into this. The 24v input connector will require a 24v power supply within 33ft of the camera and an extra cable for power.
What PTZ camera do you have?
Most require POE+ (25w) which runs near 52v.

How are you currently powering the camera?
Using a POE switch or POE injector? Or the 24v AC transformer?

You'll need to run a separate power cable to the camera for a microphone.
Tapping into the POE feed may be possible but not something I would suggest at a DIY/cheap level.
POE pass through splitters exist, but I've never seen one at a reasonable price for POE+ output. This one is only standard POE output and your camera draws too much power for this to work.

I sense several areas of confusion in this thread. When you say the splitters say 48 volts, this is most likely their input voltage, which is standard POE voltage. (It's "nominal" 48 volts, and has an allowed range of several volts). You need to be concerned with its output voltage, which is commonly 5, 12, or 24 volts. Other voltages are available, and some splitters have a selectable output voltage. Many forum users power an external mic with what we'd call a 12 volt POE splitter. That's its output voltage.
The inconvenience is that most POE splitters do not pass the POE power to the camera connection, so you need to power the camera via its power port, which on most cameras is 12 volts, but 24 on some bigger cameras. Since you're also powering a microphone you need to power both the camera and microphone with the splitter's DC output, commonly done with a splitter cable. If the microphone and camera don't need the same voltage, the situation gets a lot more complicated. Everybody I'm aware of uses a 12 volt microphone. Some of the newer and/or larger cameras have a power out line for a microphone, which I think is 12 volts, but you'd need to verify if you have one of those cameras. Many but not all of the splitters are POE+ but it's often difficult from the descriptions to tell for sure.
