Video Analytics Solutions for City Traffic and Public Security

Challenge

Measuring the traffic flow using traditional camera systems requires a lot of human effort, concentration and time.

AI NVR Solutions

Vehicle Counting:

By knowing the number of vehicles that travel through street and freeway intersections in specific time periods, city planning departments can obtain the statistics of peak hours and types of vehicles to prepare measures to help alleviate traffic jam.

Challenge

A traffic violation is dangerous and must be avoided. However, a lot of manpower is required if a police officer needs to stand at each intersection or constantly watches a video wall to look out for traffic violations.

Wrong-Direction and Illegal U-turn Detection:

As soon as a vehicle goes in the wrong direction or makes an illegal U-turn, the notification is sent to the police department in real time.

Alert:

Using the alert trigger action setting, the police department can connect AI NVR with third-party systems to automatically export a photo of the traffic violation, the license plate of the vehicle, and any necessary information for record.

Challenge

The limited number of parking spaces in a busy city causes an increase in illegal parking, such as passenger cars parked in bus lanes, loading zones, etc., which affects traffic safety and traffic flow and is difficult for police departments to manage in the whole city.

AI NVR Solutions

Illegal Parking:

By simply setting an illegal-parking ROI, the police department will receive real-time notifications when certain types of vehicles stay in a non-parking area for more than a specific amount of time.

Challenge

Most of the time, when an illegal gathering happens in unattended areas, such as gang activities and fighting in empty parking lots, it is difficult for police to notice immediately and arrive on time to stop such activities.

AI NVR Solutions

Crowd Detection using Video Search:

To maintain passenger information privacy, without building a face database, the staff can simply upload a face image of the lost child or elderly person and see where he/she appears in front of the cameras in real time. As a result, the security staff can easily find the lost child/elderly and provide help in a short time.

Intrusion and Loitering Detection:

Store owners, train station managers, and park managers can set up alert notifications to be sent directly to local police departments and other theft-deterring measures such as shining a light onto the area or activating a message on the loud speaker when someone attempts to break in or vandalize the area.

Challenge

Legacy surveillance system requires too much time and effort to review videos when the police need to perform investigation.

AI NVR Solutions

Face Recognition:

Watchlists from local and federal police departments can be imported imto the database. As soon as a suspect or wanted person is spotted on camera and matched with the face list, AI NVR automatically sends the alert and triggers appropriate actions.

Map Tracking:

The detected face in the alerts can be tracked on a map based on the camera locations and time stamps to help the police quickly visualize their path and predict possible future locations.

Challenge

Legacy surveillance system requires too much time and effort to review videos when the police need to quickly track a stolen car or a suspect’s vehicle around the city.

AI NVR Solutions

Video Search:

Enable quick searches for the specific vehicle types and color and can be combined with LPR to search for partial license plates, reducing at least 99% of the time compared to manually reviewing videos.

License Plate Recognition:

Easily applied to any street camera so that when a vehicle on a watch list (e.g., stolen car, wanted car) appears, a real-time alert is sent to the local police.

Map Tracking:

License Plate Tracking provides the exact movement and route of the target vehicles. Police departments can use the LPR function and map view to find the stolen vehicle through street intersections, predict possible destinations that the targets may reach on their route and timely issue appropriate measures.
