PRODUCTS: VIDEO ANALYTICS



PureTech Systems is a world leader in the development and deployment of advanced video analytics / intelligent video solutions for security and safety applications.  All our analytics are internally developed and maintained by our technical staff.  New algorithms and applications are constantly being developed.  The following lists some of our more popular algorithms, each of which can be combined with the others to provide a powerful video security solution.

Objection Detection
The ability to detect objects and intrusions using various types of cameras and illuminants while ignoring normal environmental conditions

 

Slew To Cue
Not technically a video algorithm, but the capability to slew a camera or related device directly to an object’s exact position  or to precise geospatial coordinates, followed by the activation of various other video analytic functions.

 

Automatic PTZ Following (Single Camera)
The most advanced, single camera, automatic  PTZ following on the market.  Designed specifically for outdoor use, this function tracks an objects of interest at varying zoom levels.  It has the ability to change object type mid follow (EX. A person entering a vehicle), continue to follow during obstructed views, changing aspects ratios (crawling, walking, etc) and varied speeds (walking, stopping, running).

 

Stopped Vehicle
Detection that a vehicle, or other object of interest has stopped within a defined region.

 

Background Modeling
Background modeling is crucial to every form of analytic behavior intended to be used in outdoor applications.  It affords the capability to recognize traits of the background and remove those attributes from the scene.  This then allows for analysis of the remaining objects.

 

Detection within a Region
The use of video analytics becomes more powerful when allowing the ability to add additional requirements to the behavior. For example, the entrance or exit from a defined area, or a specific object type of action occurring in that area.

 

Car Counting
The ability to count vehicles with directional accuracy, while ignoring pedestrians and environmental conditions.

 

Object Classification
The identification of objects by type: human, car, truck, boat, unknown.  The subsequent classification can then be used for alarming and display.

 

Image Stabilization
Camera movement is commonplace, annoying and places havoc on most motion detection products.  The Stabilization algorithm removes this video shifting providing a stable video for 3rd party systems and operator viewing.

 

Wrong Direction / Speed Threshold
This algorithm can detect the real speed of the vehicle or object, regardless of its orientation to the camera (approaching, departing, moving across scene), as well as, the direction of movement with respect to an area of interest.  Thresholds can then be set to trigger appropriate alarms.

 

 

Dropped or Thrown Objects
The algorithm looks for objects that have been left in a location, or have been thrown into the view of the camera.

 

Loitering / Crowd Detection
Often times it is important to not only detect the object, but understand how many objects are present and whether they are remaining in a defined area for a suspicious period of time.  This behavior is covered by Loitering and Crowd Detection.

 

Camera Tampering
Video analytics can also be used to detect possible tampering with the camera.  The Camera Tampering function looks for the loss of the video image (Due to coverage or disconnection) or excessive movement of the camera (Due to removal or redirection).

 

Man Overboard
A specialized detection algorithm to detect jumping or falling targets in both land and water applications.
