The FLIR D-Series Camera provides a continuous 360° pan operation and a 90° tilt operation
with automatic flip to provide complete 180° tilt coverage. The pan and tilt speeds range from
0.5° per second to 100° per second. To accommodate typical security surveillance operations,
up to 80 preset locations can be configured on the camera. The camera can also be set to
continuously auto scan between two positions or up to 200 points can be set in a repeating
pattern.

The D-Series camera provides standard video format output via a BNC connector. The camera
is controlled using the Pelco-D protocol over RS485 serial communications, and is powered
using a 24V AC power supply. The camera is provided with a 6 foot bundled cable system that
includes the connections for video, power and serial control.
