These days, public safety is a major concern for governments as well as public and private businesses. In many cities, crime rates are rising. Gang activity, serious traffic offenses can be documented using security cameras in public areas and streets. On-premise, private-cloud AI video analytics help support local law enforcement by identifying suspected criminal activity and suspects associated with these crimes, and also detecting traffic violations.

Traffic & Parking Management

Knowing Traffic Flow

Challenge

Measuring the traffic flow using traditional camera systems require 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 jams.

Traffic Violation Detection

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 watch a video wall to look out for traffic violations.

AI NVR Solutions

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.

Illegal Parking Detection

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.

Illegal-Gathering Detection

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.

Crowd Detection using Video Search: By setting the alert rule for detecting people crowded during the special time period (such as midnight), the police department can get the notification in real time, have enough time to prepare countermeasures in case of dangerous illegal activities.

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.

Detect & Track Suspects and Criminals

IronYun AI Video Analytics_Industries

Challenge

Legacy surveillance systems require too much time and effort to review videos when the police need to perform investigations.

AI NVR Solutions

Face Recognition: Watchlists from local and federal police departments can be imported into 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.

Detect & Track Target Vehicle

Challenge

Legacy surveillance systems require 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 specific vehicle types and colors. This 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 apply 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 movements and routes of target vehicles. Police departments can use the LPR function and map view to find stolen vehicles through street intersections, predict possible destinations that the targets may reach on their route, and timely issue appropriate measures.
