With the development of AI (artificial intelligence), AI human shape recognition and monitoring systems have become a hot spot in the security industry. However, a large number of people confuse the AI human shape analysis monitoring system with the motion detection function of the nvr network video recorder. At the same time, some people with ulterior motives use the motion detection function of ordinary cameras to act as an AI human shape recognition monitoring system to earn huge profits. SHENZHEN YCX ELECTRONCIS CO., LTD. will talk about the difference between AI intelligent human shape recognition monitoring and motion detection.
1. Intelligent human shape detection of the AI IP camera
The AI IP camera's intelligent human shape detection and monitoring integrates the human shape detection algorithm module, and calculates the image sequence through the self-developed algorithm to obtain the circumscribed rectangular endpoint coordinates of the moving object, intercepts the image according to the rectangular coordinates and judges whether there is a human shape in the image and accurately locates the corresponding human shape coordinate position and then alarm through the self-developed convolutional neural network. That is to say, AI IP camera intelligent human shape detection is to detect and analyze human shape objects in the screen through AI intelligent algorithms, and filter other moving objects (such as shaking branches, moving animals, and changing light) to generate effective and targeted alarms.
2. Motion detection of the NVR network video recorder
The motion detection of the NVR network video recorder automatically obtains the coordinates of the moving target by acquiring the picture stream, and calculates whether the picture information in the coordinate system has moved, and then generates an alarm. In short, the motion detection of the nvr network video recorder is to generate an alarm as long as it detects the movement of an object in the screen.
AI IP camera intelligent human shape recognition and monitoring uses algorithms to trigger alarms only when human shapes are detected. When detecting object movement, animal movement, and screen changes, it will not alarm; while nvr network video recorder with the function of motion detection will alarm all moving objects and screen changes.
The AI IP camera intelligent human shape recognition and monitoring algorithm supports more precise alarm mechanisms such as perimeter guards and tripwires, while the motion detection of nvr network video recorder has only general regional settings.
For the motion detection of the nvr network video recorder, as long as there is the pixel change of the camera monitoring screen, an alarm will be generated. The AI IP camera's intelligent human shape recognition and monitoring system uses a background algorithm to alarm when there are activities and detention of people in the screen, which greatly improves the accuracy of monitoring.
