Intelligent video analysis technology
The combination of infrared thermal imaging and advanced video analysis algorithms is intelligent video analysis technology, which can monitor ground personnel, vehicles, and flying objects in the air. This technology can achieve the highest accuracy, efficiency, and scalability through edge-based video analysis, and perform automatic analysis to locate, identify and track targets in dynamic scenes, and analyze and determine the behavior of targets, so as to detect abnormal situations Respond in a timely manner. The application supports a variety of detection scenarios, including multiple types of intrusions and stays. It is especially suitable for high-security perimeter protection scenarios.

Features of the traditional airport perimeter prevention and control plan:
1. Traditional metal mesh protection can only play an extremely limited role in blocking and delaying invasion;
2. There is no deterrent or warning effect on the intruder, the intruder can carry out the intrusion at will and be undetected for a long time and discovered in advance.
3. Without information analysis and communication functions, it is difficult for security personnel to accurately locate in a large area.
4. Even if traditional night vision surveillance, infrared curtain walls, etc. are established, they cannot be effectively tracked when an intrusion occurs or when an intrusion is occurring, and it is susceptible to interference and false alarms in different weather environments.
5. At night, the visible light imaging system monitoring is not satisfactory in terms of observation distance and prevention effect.
6. With hindsight, the illegal intruder has caused damage to the perimeter facilities, and has even sneaked into the perimeter before being discovered.
7. The traditional infrared curtain wall, vibrating the optical cable when the weather is abnormal (hail, strong wind, rain and snow), frequently unprovoked false alarms.
8. Traditional visible light has a large blind area at night. Some night vision cameras are white light supplementary lights, which belong to visible light and have low concealment. They are not suitable for concealed monitoring; infrared supplementary light-type visible light surveillance cameras have limited observation distance.
Overview of Airport Intelligent Video Analysis Solution
FLIR infrared thermal imaging intelligent video analysis system, a real civilian security product, excellent performance, economical and applicable, both core video analysis technology and super cost-effective coexistence, designed to deal with challenging environments, harsh weather conditions, and Run in complete darkness. The built-in video analysis software contains advanced video analysis algorithms, DDE digital image enhancement algorithm, specifically used to analyze thermal surveillance videos.
It detects and tracks various types of movement, and compares them with pre-established parameters. Intelligent analysis tools can distinguish accidental intrusion events of people, vehicles, animals and plants. Through a friendly user interface, you can create custom trip nets, isolation zones, temperature alarms, and directional alarm rules. Once the sensor management software detects unauthorized movement, it will trigger an alarm. And may replace multiple visible light cameras and reduce the total cost of ownership. Combine first-class thermal image details and edge analysis in a single device.
Principle analysis of smart sensor array
The smart sensor system solves the problems in different areas through different installation methods. Below is the fence type perimeter, and the smart sensor is installed directly above the fence.
The front-end system divides the scene into several zones as defense zones, and each zone can define a penetration alarm level.
For example, if an intruder starts to penetrate from the right side, when invading into area 1, you can set the system not to warn the central control room (which can reduce the pressure on the staff), and only turn on the on-site sound and light alarm to form a warning effect for the intruder. When the intruder continues to penetrate to the No. 2 tripwire, the system informs the central control room (or activates the PTZ dome-camera linkage). When the intruder continues to invade to the No. 3 area, PTZ starts to track the intruder to help the patrol personnel carry on the scene position. The front-end intelligent analysis includes scientific and reasonable division of regional warnings, which can effectively avoid false alarms and can reflect the development of the situation.

System advantage analysis
Airport perimeter smart sensor array perimeter intrusion early warning system, features:
Advantage 1: Intelligent classification and reduction of false alarms
This airport perimeter intelligent infrared sensor uses active and passive methods for detection (can classify targets and make judgments on intrusions)
Using visual mapping three-dimensional modeling and adaptive Ai algorithm for effective target and non-target identification algorithm.
The identification of people, animals, and vehicles through its own patented algorithm can effectively avoid false alarms
Traditional optical fiber-based'vibration fence' systems, when objects hit the fence or other things produce vibrations, these systems will send out alarms. The problem is that these alarms may be caused by dogs, wild animals, cyclists hitting fences, branches Caused by wind, none of these pose a threat to safety. Then these events need to be independently confirmed by the camera. This requires additional steps and therefore consumes valuable time. The data provided by the FLIR thermal imaging camera is to directly identify the threat and effectively call the police.
Advantage 2: High-performance analysis and low false alarm rate
With the help of three-dimensional algorithms and smart sensor arrays, zero false negative rate can be guaranteed in the field application environment.
With automatic tracking and intelligent identification capabilities.
Built-in powerful analysis tools, reliable performance, reduce the probability of false alarms and eliminate false alarms
When thermal imaging cameras detect the smallest differences in thermal signals, they produce clear, high-contrast images, which are ideal for video analysis, detection, and classification. With the help of a thermal imaging camera, embedded analysis can immediately distinguish the animal at a specific distance from the human at a distance of how many meters according to the direction of the animal's movement.
Advantage three: remote detection and flexible coverage
We use the thermal imaging system to construct the airport perimeter defense system, which is truly realistic to achieve effective prevention of perimeter intrusions rather than hindsight
At the airport perimeter, thermal imaging detectors with different detection distances and ranges are selected according to the on-site environment, and lens equipment with different focal lengths can be used to cover the monitoring site according to the on-site environment.
