[0002] Video surveillance is an important part of the security system. It is a comprehensive system with strong prevention capabilities. Video surveillance is widely used in many occasions because of its intuitiveness, accuracy, timeliness and rich information content. In recent years, with the rapid development of computers, networks, image processing and transmission technologies, video surveillance technology has also made great progress. Now video surveillance has been widely used in various fields, especially in the field of building security monitoring. Building security video surveillance system is an advanced security system used to monitor and record what happens in the building. This system is widely used in various buildings, such as offices, shopping malls, factories, hospitals and residential areas. Its main purpose is to ensure the safety of the building and prevent criminal activities. Building security video surveillance system usually consists of several main components: cameras, monitors, storage devices and control centers. Cameras are usually installed in various The monitoring system is used to monitor and record important areas such as halls, corridors, elevators, parking lots, etc., to capture and record any activities. The monitor is used to display the images captured by the camera so that the security personnel can monitor the situation in the building. The storage device is used to store the captured video data for subsequent playback and analysis. The control center is used for the overall control and monitoring system so that the security personnel can monitor the situation in the building in real time. Among them, the role of surveillance cameras is particularly important. A large number of surveillance cameras need to be installed in the monitoring system to achieve the purpose of no-dead-angle monitoring.

[0015] Compared with the prior art, the beneficial effects of the utility model are: the building security video monitoring device has the following advantages:

[0016] Insert the mounting seat into the base. As the mounting seat is inserted, the upper end of the top plate contacts the top wall of the base. As the mounting seat continues to be inserted, the top plate is forced to move the slide bar downward, and the top block moves downward synchronously. The tension spring 1 is forced to expand downward. As the top block moves downward, the lower end of the outer surface of the top block contacts the outer end of the locking column, and the inner end of the locking column is forced to move outward. The tension spring 2 is forced to expand until the outer end of the locking column is inserted into the locking hole. The upper end of the mounting seat fits with the lower end of the base. At this time, the initial fixation is completed, and then the slip ring is pulled down to move the limit frame downward. At this time The limit frames are aligned with the notches of the adjacent limit grooves, and the top ring moves downward accordingly. The spring is compressed under force until the lower end of the limit frame enters the interior of the limit groove, and then the slip ring is rotated forty-five degrees to the left to align the lower end of the limit frame with the groove. Then the slip ring is released, and the spring expands upward without force, driving the top ring to move upward, and the slip ring and the limit frame also move upward until the lower end of the limit frame contacts the top wall of the groove. At this time, all installation work is completed, and the sliding rod, top sheet and tension spring form a downward force on the camera, and the top ring, spring and limit frame form an upward force on the camera. The forces in two directions interact with each other, and the fixing effect is optimal. After the installation is completed, the camera can work. The single-chip microcomputer controls the lens to shoot the picture. The shot picture is converted into an electrical signal by the image sensor and transmitted to the single-chip microcomputer, and then transmitted to the monitor in the control room by the single-chip microcomputer to complete the monitoring purpose. When the camera is repaired and maintained, the camera needs to be disassembled, the slip ring is gently pressed down, and the limit frame is moved down. The top ring moves down synchronously, and the spring is compressed. At this time, the lower end of the limit frame leaves the groove, and the slip ring is turned forty-five degrees to the right to align the limit frame with the limit frame again. The notch of the positioning slot is formed, and then the slip ring is released. The spring expands upward without force, driving the top ring to move upward, and the slip ring and the limit frame also move upward accordingly. The limit frame leaves the inside of the limit slot, and then the mounting seat is gently pulled down, and the mounting seat moves down. The tension spring 1 contracts upward without force, driving the slide rod and the top block to move upward, and the inner end of the locking column is not subject to force. The tension spring 2 contracts, driving the locking column to return to the inside of the step hole. At this time, the mounting seat is completely free from restriction, and the disassembly work is completed. The surveillance camera can be quickly installed and disassembled, which greatly shortens the installation and disassembly time, reduces the labor burden, and is very convenient.
