This excellent unit uses the very latest
technology to detect movement in the camera video output. This
makes it ideal for protecting individual items or areas that
are in the camera's vision, such as a till, doorway, locker,
vehicle door handle etc,
motion detector has at least 5 major advantages over P.I.R. detectors.
is no need for any separate detection devices ( as it uses the
actual picture) making it ideal for covert use and also in vulnerable
or vandal prone situations.
it uses the actual picture, it can be used to detect motion through
glass, making it easy to set up a concealed camera, viewing through
can be set up to ignore most of an area, but will trigger when
someone, for example, picked up a handbag, tried a car door handle,
or opened a till draw or a cupboard.
detection area ( or dot ) can be re-positioned in seconds, to cover
a different area e.g parked vehicles which are not in the same
place every time.
a multi-camera situation, the motion detector can be easily moved
to a different camera as required, making it very flexible and
economical to use.
Once connected, the video motion detector works using an "on screen display" consisting
of four white rectangles. These rectangles can be positioned anywhere in your
visual display, they can also be adjusted individually, horizontally or vertically
to cover a larger or smaller area ( see pictures ). Once you have positioned
the rectangles to protect the area you require, you can choose whether the
dots remain visible or not on your monitor and VCR.
there is any movement or sudden change of light level in the selected
area, the video motion detector goes into an alarm condition emitting
an audible warning tone ( which can be silenced if required). The
unit has several different types of alarm contacts, that can be
used to activate other equipment when in alarm mode, e.g. the Automatic
Video Controller or an alarm system, this makes it ideal for unmanned
or rarely visited sites.
use of this equipment, in a rarely visited or remote site, can
by utilising the automatic video controller and a normal domestic
VCR give good coverage, without the labour intensive problems associated
with time lapse VCRs.
