Intelligent surveillance products are not affordable for everyone
At present, the most common monitoring is still video monitoring equipment. The operating principle of video monitoring is to track and protect the monitored video by monitoring and recording the image information. At present, it has a wide range of applications, such as military agencies, customs, public security, fire protection, etc. All industries will see the operation of video surveillance. So, do you know what smart monitoring products are? At present, the monitoring equipment in the world is also constantly developing, and the speed of development is rapid. Join me today to take stock of smart monitoring products that have been evolving over the years.
Intelligent behavior recognition and classification
1. Intelligent monitoring object recognition
It can distinguish the type and behavior of moving objects, whether it is a car, a motorcycle, a person, an airplane, etc. At the same time, it can also judge whether the moving object is walking, falling, speed or other, which is the basis of other recognition.
2. Intelligent monitoring cross-border identification
By artificially drawing a line or curve on the video screen, you can recognize the behavior of objects crossing this limit. For example, the field of vision is a road. Draw a line to divide the road into two ends. Assume that it is legal from left to right and illegal from right to left. Once the vehicle travels across this boundary, the device judges whether it is illegal. If it is illegal, an alarm will be generated. .
3. Intelligent monitoring trajectory tracking
After recognizing the moving object, you can draw the trajectory of its movement through the place behind the moving element. In public places such as squares and stations, where people flow, the device can display and record everyone's trajectory. If a person wanders in the field of vision for a long time and exceeds a certain period of time, the device automatically alerts you to find suspicious behavior figures.
4. Intelligent monitoring for identification of left or lost objects
The device can recognize that there is one more object or one less object in the field of view. It is suitable for warehouses, stations, exhibition halls, security inspections and other places. If a backpack is lost for a long time and no one picks it up somewhere, the system will generate Alarm, or in places like exhibition halls, if a piece of display is missing, the device can also find and alarm.
5. Intelligent monitoring license plate recognition
If the video scene is a road junction or community entrance; as long as the license plate area appears in the video, the device can automatically recognize the license plate number; and prompt the user in text. It can be used for the inspection of illegal vehicles. For example, if a license plate vehicle escapes after an accident and does not know where to go, if there are intelligent video servers at all major crossings in the city, the system can only set one or several license plate numbers to be checked into the system at a time through the network. In the various smart devices in the system, once the vehicle with this license plate appears in the field of vision, it can immediately alert. Save many police resources.
6. Intelligent monitoring vehicle speed measurement
For example, there is a 200M speed prompt area on the highway, which always reminds the driver not to speed, but speeding still happens frequently; imagine if you install an intelligent video server on the highway, we only need to draw two lines in the field of vision, if you know this The actual distance between the two lines is 100M. When input into the device, the device can automatically calculate the speed of each passing vehicle, and immediately alarm when overspeed.
7. Intelligent monitoring traffic statistics
Smart devices can identify passing pedestrians and vehicles, and at the same time can count the number of passing people or vehicles; Imagine installing such an intelligent device at a crossroad or the entrance of a convention center to count the passing traffic or people flow. Provide more and more timely information for bus dispatch.
8. Intelligent monitoring retrograde alarm
For example, the one-way street, or the exit or entrance of the station or airport, the traffic flow is one-way. Once someone reverses, the system will automatically recognize and generate an alarm.
9. Intelligent monitoring graffiti behavior recognition
The original clean wall was garbled with small advertisements, phone calls or graffiti, etc., which hindered the city appearance. With the intelligent monitoring system equipment, such graffiti behavior can be discovered in time and alarms can be given in time.
10. Video of abnormal behavior such as intelligent monitoring fights
In public places such as parks, squares, and stations, there is a large flow of people. Any sudden behavior that jeopardizes personal safety may cause significant losses and negative effects. The intelligent recognition system can detect abnormal behaviors of people or vehicles in a timely manner, such as sudden running, falling, chasing and other behaviors. The system will find and remind managers in time.
What are the intelligent monitoring products
However, with the advancement of surveillance technology, other different surveillance devices have appeared, but until now, image surveillance technology is still the core content of video surveillance. From the earliest analog video surveillance to digital video surveillance system to the current embedded DVR surveillance. The intelligent monitoring equipment is a purely analog video monitoring system composed of a camera and a monitor (TV), which is called a closed-circuit monitoring system. From the initial one-to-one camera to the monitor to the embedded high-speed mass processing, the development of intelligent monitoring has been greatly improved.
But for functional monitoring, there are still many defects. The first is the weakness of human nature itself. The most uncontrollable is human nature. And in many cases, playback can't reflect people's psychology. More importantly, even intelligent monitoring can't directly reflect people's psychology. A buffer process is needed. The second is the monitoring range. No matter what kind of monitoring site, there will always be a dead end that the monitoring cannot involve. Finally, there are false positives and false negatives and difficult data analysis. No matter how advanced the intelligent monitoring equipment is, or people need to be analyzed, this time will cause false positives and false negatives.
So far, the well-known monitoring equipment also includes advanced video motion detection, object tracking, and face recognition. Advanced video motion detection refers to severe weather, such as strong winds. When heavy snow and other influences are used, accurate detection is performed using changes in object motion. Object tracking refers to the use of advanced monitoring equipment to detect moving objects and automatically send PTZ control commands according to the movement of the objects. Then the camera monitoring system will automatically track the objects. Face recognition is because the identity of each person has been entered into the computer, and when only the facial features of the person need to be recognized, the information already entered is used to determine the identity of the person. In addition, there are a series of intelligent monitoring products such as crowd control, infrared recognition, fingerprint recognition, and traffic flow control.
Editor's summary: In the "Speed ​​and Passion 7", which was sold at the box office not long ago, there was a process of fighting for "sky eyes" with each other. In the play, "Sky Eye" is a perfect monitoring system that can invade various monitoring devices around the world and directly locate the person or thing that you want to track.
