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.
