Description

Technical Field

[0001] The invention relates to the field of security monitoring and alarm, and in particular to a dangerous behavior monitoring and alarm device based on a security monitoring system. Background Art

[0002] The dangerous behavior monitoring alarm device based on the security monitoring system is based on video surveillance and uses image processing, pattern recognition, machine learning and other technologies to automatically detect abnormal behavior or potential threats in the video and issue an alarm in time. This device has broad application prospects in public safety, smart home, industrial safety and other fields.

[0003] At present, intelligent intrusion monitoring and analysis technologies are mainly divided into two categories. One is to use visible light cameras to extract and detect targets in video images, and use various rules to distinguish different events, so as to achieve different judgments and generate corresponding alarm linkages. The second category is to use infrared, microwave and other sensors to perform intrusion monitoring. However, traditional visible light cameras do not provide enough privacy protection, are highly dependent on light, and the accuracy of near-human infrared detectors is low.

[0004] However, traditional indoor fire monitoring uses smoke sensor alarms to detect and alarm based on the smoke concentration in the environment. The smoke detector warning has high requirements for the use environment, has a short working distance, and does not have a visualization function. It often cannot detect the fire in the first time, making it impossible to effectively control the fire, causing serious economic losses. However, in real life, there are many cases of smokeless fires, such as electrical fires, gas fires, etc., which cannot be detected by smoke sensors. Therefore, traditional smoke sensors have problems such as low detection accuracy and high false alarm rate.
