The hospital has an important mission to protect the health of the whole people, but this year's vicious wounding incident occurred in hospitals. In order to build a comfortable and safe medical environment, it is necessary for the hospital to establish an integrated security management system. The security management system mainly uses video surveillance systems, perimeter systems, access control systems, and other supporting facilities to fully exert civil air defense and physical defense. The combination of technical defenses ensures the orderly management of hospital security.
The video surveillance system mainly consists of three parts: front-end camera, power supply and signal transmission, and monitoring center equipment. The front-end camera is designed in the hospital entrance and exit, main trunk roads, parking lots, import and export of functional buildings, halls, passages, elevator halls, stairways and some important places including registered toll collection, hospitalization registration, nurse station, infusion room and Different types of cameras are installed in the baby room and other areas for video surveillance. The center sets up the storage device, the control device, and the display device, and transmits the video signal of the front end to the center for storage and display through a dedicated line. The size of the front-end camera section, its quality and the quality of the image signal it will affect the quality of the entire system, combined with the hospital's monitoring features, in accordance with the following principles when selecting a camera:
The perimeter of the hospital and the entrance and exit of the park are the first line of defense for intrusion prevention. The perimeter uses outdoor fastball and infrared cameras to record video information all day long; the entrances and exits of the gates and other entrances and exits connected to the outside world use HD outdoor fastball and gun cameras. The ball has infrared function, which clearly distinguishes the facial features of the entering and exiting people all the time, and realizes fast positioning and tracking of the target; the gun has strong light suppression, and clearly records the entry and exit of the motor vehicle brand.
The outdoor parking lot covers a large area and has ambient light at night. However, when the light is not ideal, the low-illumination camera is used to obtain good image effects. The underground parking lot has poor lighting and many dead ends. The machine monitors the entire basement and is designed to leave no dead ends.
In the outpatient hall of the building, because the flow of people is large, the personnel situation is complicated, and the task of monitoring is heavier. In this case, multiple cameras are simultaneously monitored, and multiple cameras are installed to point to different orientations, and combined with the indoor hemisphere, Real-time monitoring of different locations (ie, "X+1" mode formation) at the same time in one monitoring point increases the scope of monitoring. At the same time, for the door position, intelligent analysis, such as face capture, traffic statistics and so on.
The hospital's registered toll hall and the charges on all floors are occasions with large cash flow. Recording the trading situation is of great significance for the future verification of the hospital and the usual safety management. At the same time, the continuous monitoring screen is added as much as possible in the arrangement of the monitoring points. A special monitoring channel for cash flow is formed to ensure key monitoring of cash. The color HD camera is used to correspond to the registered charging counter.
To meet the requirements of hospital aesthetics and concealment, indoor public areas such as aisles and elevator halls are installed with colored hemispheres. High-definition infrared hemispheres are used in the operating room, ICU ward, baby room, nurse station, drug storage room and monitoring center. The image is clear, ICR infrared filter-type automatic switching, automatic color-to-black function, and day and night monitoring are realized. The front end sets the pickup to achieve audio and video synchronization recording. The hospital is a special place for 7*24 all the year round. In order to achieve 24/7 monitoring needs, especially in the absence of lighting, such as corridors, cameras require infrared night vision. Important hospital rooms, such as pharmacies, warehouses, materials rooms, and valuables storage rooms are the key parts of monitoring. With fixed angle monitoring, the camera needs to have high definition. The resolution of the color hemisphere, infrared hemisphere and gun camera should reach 1.3 million pixels or more, and the color black and white is automatically converted, and the picture is clear and vivid.
