Automatic Incident Detection on PTZ cameras

Product overview

VisioPaD is a video-based Automatic Incident Detection (AID) system for highways and bridges that operates on PTZ (Pan-Tilt-Zoom) cameras. It provides real time detection of incidents and accidents as well as traffic data.

The operation on PTZ camera even when a camera is out of preset is unique to Citilog’s VisioPaDplus and VisioPaD.

VisioPaD allows fast automatic real time incident detection with an alarm and on-screen display of incidents within a few seconds after an incident occurs.
Fast detection enables a proactive response to incidents and accidents and thus limits the risks of secondary accidents, minimizing human casualties and infrastructure damage.

VisioPaD operation

VisioPaD is a self-learning and self-calibrating solution. When started, VisioPaD learns the environment and the traffic and is ready to detect within minutes. When a PTZ camera is moved, VisioPaD re-learns the environment and the traffic and is ready to detect again within a minute.

Benefits: Mobility and Safety

With a quick detection of incidents by VisioPaD, it is easier for Traffic Control Centers to track incidents in real time and then to anticipate congestion. With faster notification of accidents, oncoming drivers can anticipate, adjust their speed and avoid secondary accidents. The risk of congestion is reduced, which improves mobility on roadways.

With digital video recording of incidents, an investigation into the nature and cause of incidents are possible.

Return on Investment

With quick detection for any type of incident - large or small - the system can enable plans for action for traffic managers to better protect investments in infrastructure. VisioPaD helps maintain a high level of availability of roads, thus enhancing the Return on Investment both in operations and in risk escalation reduction.

Because it can be easily deployed on existing PTZ Cameras, VisioPaD provides unrivaled seamless installation.
