VIDEO MANAGEMENT SYSTEMS - CHAPTER 11
Description
Simple magnetic switch that
detects the opening of doors or
windows.
A sensor that detects motion
based on heat emission.
An active sensor that measures
air pressure in a room and
detects sudden pressure drops.
(The sensor can be powered by
the camera.)
Description
A relay (solenoid) that controls
the opening and closing of door
locks.
Alarm siren configured to sound
when alarm is detected.
An alarm security system that
continuously monitors a
normally closed or open alarm
circuit.
Usage
When the circuit is broken (door is
opened), images/video as well as
notifications can be sent from the
camera.
When motion is detected, the PIR
breaks the circuit and images/video
as well as notifications can be sent
from the camera.
When a drop in air pressure is
detected, the detector breaks the
circuit, and images/video as well as
notifications can be sent from the
camera.
Usage
The locking/unlocking of a door can
be controlled by a remote operator
(over a network) or be an automatic
response to an alarm event.
The network video product can
activate the siren either when motion
is detected using the built-in video
motion detection or using "informa-
tion" from the digital input.
The network video product can act as
an integrated part of the alarm
system that serves as a sensor,
enhancing the alarm system with
event-triggered video transfers.
