In the halls of financial institutions, self-service banks, ATM cash machines, monitoring equipment will be installed to prevent some emergencies. Those cameras often use the motion detection trigger alarm recording mode. They constantly work and often produce a lot of garbage videos. When they want to trace the source, they will cause great trouble for the staff.
The use of human activity detectors at ATM counters, self-service banks, etc., can automatically open the video when someone enters the control area and monitor their operation in real time. When there are over-excited actions, alarm information will be issued in time. In addition, because alarm recording is triggered to eliminate the generation of junk videos, on the one hand, hard disk space is saved, and hard disk damage is not caused by continuous work over a long period of time. On the other hand, when there are some controversial incidents, it is called out at that time. Video viewing and forensics will also become easier.
In addition to financial and industrial and other places, human activity detectors play a crucial role in various security systems. In a smart home system, doors and windows can be opened and closed by a human activity detector. For example, standing in the bathroom door, the toilet door opens immediately, or when an infant climbs onto a balcony window sill, the window is closed automatically. , and send a warning message to parents.
In the entrances and exits of various types of warehouses or some confidential departments, human activity detectors are used. If anybody invades or accidentally breaks in, on the one hand, the accidental intruder will leave by voice and send an alarm signal to the person in charge of the warehouse. On the other hand, Open the alarm video to record the physical characteristics of the intruder and provide more convenience for the police to investigate and collect evidence.
The management of some dangerous areas has always been a difficult problem. For example, reservoirs, ponds, areas where wild beasts are infested, and even if there are signs of prohibition from approaching, whether deliberately or unintentionally, various kinds of such things as drowning occur. Such accidents have never been less. If the human activity detector is installed next to it, it can effectively prevent people from intruding accidentally. After someone enters the control range, it will drive an alarm device and cooperate with voice prompts to play an effective preventive role. Listening to dissuasion, staff members can also promptly dissuade them. If you cooperate with the camera, video recording when there is a situation can also be used as evidence to prevent disputes.
We can see that human activity detectors play an extremely important role in many security facilities, whether it is to prevent and deal with various crimes, or to provide convenience for people's daily lives, or to protect the vital interests of more people. With the further development of science and technology, the sensor may be able to further perceive people's proximity, further develop the perception of people's physical condition, and provide more perfect services for human beings.
