SW-D7000U, 9CH. COLOR VIDEO MULTIPLEXER
A single full-screen alarm will be frozen, if the option was selected in the
However this option will be ignored for multiple full-screen alarms on Monitor-A.
EXTERNAL ALARM ACTIONS (RELAY OUTPUTS)
Two alarm relay outputs are provided to enable the programmer to program automatic external
actions such as a speed change on the VCR, or alarm floodlights or sirens. The alarm relay outputs
are rated at 500 mA. They are provided in either the normally open (N/O) and normally closed (N/C)
configuration on the rear panel of the unit (programmable), and are isolated.
The alarm relays can be activated by motion detection, by active alarms, by video loss, or by MACRO
functions. The choice of which relay is activated by which event is selectable via the menus.
Selecting the Relay Outputs linked to Alarm Inputs:
Once EXTERNAL ALARM ACTION is selected, a menu will appear, allowing the programmer to
select one of the following four choices for each alarm input:
" None
"
Relay 1
" Relay 2
"
Relay 1&2.
NOTE: When making this selection, remember that video loss and motion detection can also be
programmed to activate one of these output relays.
Factory default settings for Alarm Output Relays are:
All Alarm Inputs
All Activity Detection
Additional alarm output data:
The SW-D7000U also allows the programmer to read the status of alarm inputs for each camera via
the RS-232 remote control port.
RECORD MODE
The programmer can select NORMAL recording, EXCLUSIVE recording or INTERLEAVED recording
to take place whenever an alarm occurs. The latter two modes will always result in a faster update to
tape of a camera in alarm. This is a system wide (global) setting, and is not set up individually for
each alarm input.
Normal:
NORMAL recording during alarms means that there is no priority recording for the cameras in alarm,
and the record list will be unchanged while alarms are active. However, the programmer can still
program the VCR and the unit to switch from a time lapse speed to a faster recording speed during
alarms, which by itself can ensure that alarm events have a faster update speed.
Exclusive:
EXCLUSIVE recording will cause the system to record only alarmed cameras. All non-alarmed
cameras are omitted from the record list while an alarm is active. EXCLUSIVE recording mode is
typically chosen only when several simultaneous alarms can be expected to occur very often, and
where a near real-time record of those alarm events are needed. The disadvantage of choosing this
mode is that other cameras will not be recorded at all while any alarm is active.
