Axxon Intellect video detection tools

Basic Video Motion Detection

Video Motion Detection (VMD). A group of detection tools designed to detect moving objects in the frame. The basic motion detection tool detects motion in the scene as it looks for anything that is different from one video frame to another. An object tracker detects motion and its direction, and can track an object even if the camera is shaking or while the PTZ camera is rotating. The infrared detection tool (for its operation an infrared imager is needed) is triggered by motion in the infrared range. The motion direction detection tool captures motion in set directions.

The abandoned object/Object disappearance detection tool notifies of the appearance of an object in the scene or the disappearance of an object from the scene. This tool makes it possible to detect, for example, the disappearance of a laptop from a desk, a briefcase left in a building lobby, or an illegally parked automobile.

Facial recognition detects the appearance of a human face in the scene, distinguishing it from any other object.

Scene analysis

This group of detection tools makes it possible to filter set types of movement of an object in the scene. The user configures lines, polygonal zones and time intervals, and the system detects events corresponding to the set criteria. Scene video detection tools capture:

Any of these tools can be fine-tuned to track a specific object: a person, an automobile or all objects.

Camera Tampering

Intellects camera health detection tools trigger in case of malfunctions in a video camera's operation. They not only make it possible to identify attempts to disable a camera, but also detect various kinds of interference which reduce the quality of event recording.

The covered lens detection tool is triggered by all instances of accidental or deliberate covering / blocking / spray-painting of the lens. This is especially important in situations when a camera is located within reach.

The camera blinding detection tool generates an alert if a beam of bright light, such as a flashlight, searchlight or automobile headlight, is directed into the lens.

The camera shift detection tool notifies of reorientation of a camera in space. This detection tool is especially needed in situations when a camera is located within reach and can easily be turned.

The background change detection tool reacts to changes in the background in front of a camera. This detection tool is very similar to the previous one, but serves somewhat different purposes. While the camera shift detection tool reacts to manipulation of the camera itself, the background change detection tool reacts to manipulations around it, for instance, an attempt to place an artificial background in front of the camera.

The defocusing detection tool notifies of loss of image sharpness as a result of defocusing or dirtying of the camera lens. This is possible, for example, if someone deliberately or accidentally disturbed the focus.

Besides its own video analytics functions, Intellect supports the embedded video detection tools of IP cameras, and also can work with specialized video analytics devices.
