F. 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,

aphoto-coupled input, and RS-485 interface. The RS-485 is typically used for pan/tilt/zoom control.
