Access Control Module
Viisec Supports ONVIF Digital Outputs.
This means Visec supports 99.99% of Onvif Cameras with access control.
When inputs or outputs are triggered specific events can be triggered.
For example, when a door opens automatically -> turn a light on and record for 2 seconds.
A series of complex events can be triggered.
For example the following sequence can be easily programmed:
When a Door Sensor is Triggered- Do the following:
- Set PRESET of an Axis PTZ camera to move to that location.
- Turn on Adjacent Lights
- Activate Siren
- Lock Down Adjacent Doors
The range of devices that can be connected to an input port of a network camera or video server is almost infinite. The basic rule is that any device that can toggle between an open and closed circuit can be connected to a network camera or a video server.
|Door contact||Simple magnetic switch detecting opening of doors or windows||When circuit is broken (door is opened) the camera can take action, sending full motion video and notifications|
|Passive infrared detector (PIR)||A sensor that detects motion based on heat emission|| When motion is detected, the PIR breaks the circuit and the camera can take action |
sending full motion video and notifications
|Glass break detector|| An active sensor that measures air pressure in a room and detects sudden |
pressure drops (can be powered by the camera)
|When an air pressure drop is detected, the detector breaks the circuit and the camera can take action sending full motion video and notifications|
I/O usage example: A camera attached to a window switch and to an alarm system/siren
The output port's main function is to allow the network camera or video server to trigger external devices, either automatically or by remote control from a human operator or a software application.
|Door relay||A relay (solenoid) that controls the opening and closing of door locks||The locking/unlocking of an entrance door can be controlled by a remote operator (over the network)|
|Siren||Alarm siren configured to sound when alarm is detected||The network video product can activate the siren either when motion is detected using the built-in video motion detection (VMD) feature or using "information" from a digital input|
|Alarm/intrusion system||Alarm security system continuously monitoring a normally closed or normally open alarm circuit||The network video product can act as an integrated part of the alarm system serving as a sensor and enhancing the alarm system with event triggered video transfers|
