PTZ5A4M-25X showed up today, but it's late in the day and raining, so it will have to wait for now. One thing I notice is the power supply does not have plugs, but bare wires and the supply is 24 volts which the current power supply for the PTZ out there now is 12 volts. So, it looks like I'll be changing the supply and adding barrel plugs for power, cause I ain't trying to wrestle the thing up there and try and make hard connections to it.
Good thing is the current PTZ mount is exactly the same so that's a plus
