Installation & Service Features
In alphabetical order:
•
Daisy-chaining. Control cables can be daisy-
chained from dome to dome (10 domes maximum
for RS422), using up to 914m (3000’) of cable.
(RS422 uses two, 22 AWG, individually shielded,
twisted pairs; SensorNet uses one 22 AWG twisted
pair without a shield.)
•
Interchangeability. Each dome can be easily moved
to a new location.
•
Internationally-recognized connectors. Compos-
ite and video cables from the controller connect to
the dome via internationally recognized screw-
terminal connectors. The dome address can be
changed without cable disconnect (powering down
the dome).
•
Line lock. The dome can free-run on its own
internally-generated 2.5MHz signal, or to prevent
picture rolling on the monitor, be sync’d to a 50 and
60Hz ac source.
•
Power and communications LEDs. On the dome’s
Unicard, green power and yellow communications
LEDs (same as on the J-Box) indicate that power
and data are reaching the dome.
•
Remote manual dome reset. The dome can be
manually reset using keyboard commands from the
console.
•
Safety. The camera dome meets all international
regulatory agency standards. Electrically, the dome
uses low-voltage Class 2 circuitry, and cable
connectors keyed to eliminate electrical hazards
during use. Indoor domes use safety chains to anchor
the dome to building structural members and a safety
lanyard to retain the chassis in its housing during
servicing.
•
Snap-Hinge Chassis. Two sets of spring-loaded
locking pins enable the light-weight, camera chassis
to swing out of its housing for servicing or removal.
•
Simple Disassembly. Only a Phillips screwdriver is
required to disassemble each motor (2 screws), the
slip ring (2 screws), the camera /bracket assembly (2
screws), and each pc board (3 to 4 screws). The
dome can be located up to 250m (820’) from the
junction box.
•
V-Phase Adjustment. The dome has a remote V-
phase adjustment that enables synchronization to any
line phase by one person at the control console.
