7.5 I/O Terminal Application
Typically used in association with programming scripts for developing applications for motion
detection, event triggering, alarm notification via e-mail, and a variety of external control
functions. The 6-pin I/O Terminal Block is located on the rear panel and provides the interface
to: a photo-coupled switch output, a photo-coupled input, and RS-485 interface. The RS-485 is
typically used for pan/tilt/zoom control.
