Access Control Module

Or when a door sensor is triggered you can choose a PRESET of an Axis PTZ to move to that location. E.g. a door opens in an apartment complex, the Axis PTZ camera then swings to that AXIS preset location.








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


Digital inputs
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.

 

Device type Description Usage
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

Digital outputs
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.

 

Device type Description Usage
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
