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 8-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.
