Intrusion Detection

Intrusion Detection

Brewster Alexander now provides Video Analytics on all of our IP Cameras.  Advanced Intrusion Detection can detect when an object stays in an area for a certain amount of time.  Once an object enters the intrusion zone the camera can perform several actions.  The camera itself can send an email, upload images to a FTP site, trigger alarm inputs and outputs, and notify video workstations running our remote software.  Also, when you use our Advanced Tribrid Video Servers the servers will also capture and mark the video with the alerts, allowing you to playback and view live the events.  The server will also send realtime alerts to workstations with live streaming video.  All of the zones, and events and alert rules can also be scheuled to run at certain times.  Below is a screen shot of the setup screen for Intrusion Detection.  Below the screen shot is a short explination of the settings.


Region:  This selects the region that you are currently changing the rules for.  You can have up to 4 regions.

Threshold: Range 0 to 10 seconds. This is the number of seconds that the object must remain in the region before it is considered an alarm.   If the value is set to 0 then as soon as an object enters it will cause an alarm.

Sensitivity: Range 1 to 100.  The value of the sensitivity defines the size of the object which can trigger the alarm, when the setting is set to a high value a very small object can cause the alarm.  So if you only want to detect something like cars this settings should be low.

Percentage: Range 1 to 100. Percentage defines the ratio of the in-region part of the object which can trigger the alarm.  For example, when you set the percentage to 50, half of the object being tracked must enter the region before it is considered an alarm.
