Nothing that small or cheap.

Yes, that is what I have done. I have used a tap to make threads also.

Also, do PTZ cameras require any seperate cable or do they just work on the standard ethernet (poe) cable. And is there a limit to how many you can have? Looking at getting 2 connected but only have POE ethernet cables run to the point.
 
They use just an Ethernet cable. Big PTZs, need POE+ switches. I have started, with a POE+ switch to avoid any issues and upgrades later on.

Some of the really big PTZ's may need Hi-POE, so check power requirements before you buy one of these big boys. Even some of the POE+ switches, are very marginal in actually outputting power. As evidenced by my big PTZ constantly rebooting when connected to the switch. I had to purchase an external POE+ injector before it would power up correctly.
 
I have a 130W Poe+ switch and I don't have any issues.
