Nexus for Video Analytics

Nexus for Video Analytics is designed to reduce the information burden for operators responsible for monitoring surveillance camera images by providing real-time alerts and messages.

Outdoor/Indoor Security Scenarios

Outdoor Security

In this video, a person suspiciously abandons a package in front of a building and then runs away from the scene. As a result, our video analytic software detects that an object has been dropped into the scene and raises a red alert so that proper action can be taken by a human operator.

Indoor Security

This example exhibits a classical indoor security application often referred as the burglar scenario. In this video, a static scene is being monitored to detect changes and, in particular, the removal of background objects. A first change in the scene occurs when a person enters the field of view of the camera. However, no alert is being raised yet. When the person steals the laptop from the desk, a persistent change in the background is identified and, consequently, a red alert is raised.

Perimeter Security Scenarios

Perimeter Security along a Fence

This example is used to detect the intrusion of a moving foreground entity within a protected perimeter. In this video, the protected perimeter is a user-defined polygon located on the other side of a fence. When a person crosses the fence, an intrusion within the protected perimeter is detected and, as a consequence, a red alert is raised. It should be noted that the alert is properly raised, without any false positives, even if environmental conditions are non-ideal (windy and cloudy) and even if the input video data is slightly out-of-focus and degraded due to compression artifacts.

Perimeter Security along a Building

This example demonstrates perimeter security along a building where two alerts are raised. An amber alert is raised when a car enters and then remains immobile in the scene. A red alert is later raised when a package is dropped and left out in the scene. This example exhibits how our video analytic software can distinguish between two similar events (stopped versus abandoned objects).

Road and Border Security Scenarios

Road Security

This example shows how our video analytic software can be used for road security monitoring. In this scene, a user-defined polygon of interest counts the number of vehicles that utilizes a street. In addition, this video exhibits two amber alerts which are raised when a car remains immobile for too long. These alerts are raised at 0:14 and at 2:16 in the video and are logged for future reference.

Border Security

This video exhibits the capabilities of the license plate recognition module which can be applied to the field of border security. As a car approaches the camera, the position of its license plate is detected and tracked over time. Once the plate’s position is known, the license plate characters are extracted. Recognized license plates are then compared to a database of allowed vehicles. A red alert (at 0:10) is raised if the plate number is not matched in the database.
