Video Motion Extended (VMX)

G-Tect/VMX is the name of a sensor for perimeter protection (outdoor protection). Any spacious premises containing objects that must be secured requires a special type of protection against intruders. This includes physical measures (fences, gates, etc.) as well as personnel and monitoring activities through video installations. Video security surveillance is particularly useful in the area between an outer enclosure and the objects to be protected.

Correctional facilities have similar and yet very different requirements: The aim here is to prevent breakouts and the providing of aid for escape by monitoring a sterile zone, which is physically secured inwardly and outwardly.

G-Tect/VMX detects movements within defined zones and automatically issues alarms when areas are entered that have been marked as sterile zones.

G-Tect/VMX was designed with two objectives:

• Reduction of false alarms
• Ease of use and configuration.

In addition, the configuration level was separated from the functional level so that changes to the functionality can be made without changing the settings.

This principle should be familiar to users of VMD. So why another sensor?

With VMD we use a field (zone) based method to detect movement. This method is proven and works, where it is needed, extremely well. However, basic understanding of the functionality is necessary to be able to set up VMD effectively.

G-Tect/VMX takes a different approach: It operates object-oriented and is thus able to recognize, observe and follow objects in an image. It also determines the directionality of the object. Using applied perspectives, it can make conclusions about the size and speed of the object.

Using this data, G-Tect can determine whether an object must be reported as an event/alarm situation.

G-Tect also learns. For instance, if a car with flashing hazard lights appears in the image and the car is otherwise stationary, G-Tect/VMX "accepts" this object after a period time as "belonging" and only reacts once a new type of movement is initiated by this object.

G-Tect/VMX detects disturbances in the image (weather, animals, insects, ...) and evaluates them as global disturbances, which do not represent a threat. At the same time, G-Tect/VMX switches to another mode, which neutralizes these disturbances for the analysis.

Note that in the section that describes the user interface, information on operation of G-Tect/VMX has been provided. Further information is available then in the section on configuration.
