The monitoring screen was so horrible
Recently, a video of “mother and daughter go home and are dragged into the house by a man in a raincoat” was spread on the Internet. In the surveillance video, a man in a raincoat suddenly rushed out of the corridor and forcibly dragged the mother and daughter who were about to open the door to go home into the house, causing widespread concern.
According to the police in Laiyang City, Shandong Province, the adult man and woman in the video had just divorced. After the woman called the police, the man in question absconded. The police arrested the man on the 11th. 현재, the man has been detained. The case is under further investigation, and the man may face the combined punishment of rape and illegal detention.
Through the monitoring screen, we can find that the victim keeps looking at the monitoring when she is at the door of her home, and the sensor light in the corridor flashes, she may have noticed something strange.
에 대한 20 minutes later, the man came out of the room and cut off the switch.
The surveillance camera head undoubtedly played a crucial role in the rapid detection of this case. With the advancement of urbanization and the development of intelligent science and technology, intelligent security monitoring has been widely applied to all property communities and all corners of the city, playing a key role in helping social security stability and criminal investigation speed.
그러므로, although social security incidents still exist, the cost of obtaining evidence in cases has been greatly reduced, and the speed of case detection has also been greatly improved. Behind this, security monitoring contributes a lot.
The core component of security monitoring is the camera module, which plays a decisive role in security monitoring.
The camera module, which is called CameraCompact Module in full, is abbreviated as CCM. It is an important electronic device for image capture.
The light gathered by an object through a lens is converted into electrical signals through CMOS or CCD integrated circuits, and then converted into digital image signals by an internal image processor (ISP), which is output to a digital signal processor (DSP) 처리를 위해, and converted into standard GRB, YUV and other image signals.
● CCM includes four pieces:
Lens, sensor, FPC, DSP
● The important components that determine the quality of a camera are:
Lens, DSP, sensor
● The key technologies of CCM are:
Optical design technology, aspheric mirror manufacturing technology, optical coating technology
In addition to playing an important role in security monitoring applications, camera modules have also been widely used in mobile phones, 자동차, 의료, transportation, property, 조작, entertainment and other fields, playing a crucial role in the intelligent upgrading and development of various industries.
