Hello ScottFuel,

Here is what the terminals on the PTZ are for.

NO: Normally Open

NC: Normally Closed

CM: Common

G: Ground

And for the G S1 S2 S3 S4 seem to be for sensor inputs.

G: Ground (used for all Sensor ports)

S1: Input Sensor 1

S2: Input Sensor 2

S3: Input Sensor 3

S4: Input Sensor 4

I hope this helps

Thanks James
