2.0 DESCRIPTION

The pan/tilts of the PT280-24 Series are mini-size, light duty, indoor units capable
of supporting loads up to 15 pounds (6.8 kg). They operate on 24 VAC.

They are factory pre-wired for pan and tilt control functions, motorized zoom lens
operation, camera power, and video. All connections are made at the input/output
connectors, eliminating the need for wiring harnesses. This greatly reduces instal­lation time, while increasing reliability and serviceability.

Pan/tilts in the PT280-24 Series are ideally suited for use with discreet surveillance
enclosures.
