1. Overview
The VS Series 2 compact desktop switchers are suitable for colour and monochrome
CCTV installations, and cater for two to eight cameras and one or two monitors.
Individual camera select keys are provided for the second monitor rather than j ust a
spot key, providing increased speed and convenience of ca mer a sele ct ion .
Independent automatic sequencing on each monitor is possible and the cameras
that are to be included in each sequence may be specified. Random sequencing
may be specified if required. In dependent dwell times are programmed via the f ront
panel keys and are stored digitally in non-volatile memo r y .
Advanced latched and unlatched alarm facilities are provided in all alarm models.
Alarm inputs are provided for connection to PIR or other detectors associated with
each camera. Alarm output relay contacts in the switcher permit control of an
external warning device or a VCR. The alarm hold time, cycle time and the relay hold
time are all independently programmable via the front panel keys and are stored
digitally in non-volatile memory.
The unlatched alarm mode is suitable for unattended operation as, in this mode, the
switcher reverts to normal oper ation when the alarms end. It may be used with both
manual and auto operation. In auto, all alarmed cameras will be sequenced. In
manual, the last alarmed camera will be selected. A flashing indicator provides a
visual indication of whether the selected camera currently has an alarm.
The latched alarm mode provides similar facilities but provides an audible and visu al
warning which the operator must manually cancel.
These switchers are robustly constructed and have BNC connectors for cameras
and monitors, microprocessor control and bounce free interval switching in all
models. Most user options may be simply selected by means of switch settings.
