Introduction
Have you ever wished that your budget friendly day-only cameras
could detect intrusions even in total darkness and make the intruder
clearly visible for video evidence recording? Now it is possible! All
the ACTi cube cameras come with
built-in passive infrared
sensor (PIR)
and with the terminal block for
digital input and
digital output (DI/DO)
.
The built-in passive infrared sensor detects human movement by
sensing temperature changes over the scene, and works even in the total darkness. Human
body heat moving across the scene will trigger PIR sensor. The alarm signal will be sent to the
control center over the IP network instantly. As the digital output of the camera can be
connected to
external lamps
or
alarm sirens
, these devices will be instantly activated upon
the detected motion. As a result, the intruder who entered the guarded area in total darkness
will instantly be exposed for high quality video shooting.
In other words,
instead of trying so hard to adapt the camera to poor lighting conditions
which quite often is a costly solution, you can simply turn the night into day when the
alarm is triggered and benefit from the best possible video quality in color mode!
