The image quality of HD is very clear, but does the prison need to adopt the HD system? This requires a specific analysis of the specific situation: the prison monitoring points are mainly two types, one is the monitoring of outdoor locations such as public places, perimeters, and the other is a large number of internal monitoring of the building. The building is generally an area of ​​about 10 square meters, so the monitoring point will not exceed 10 meters from the monitoring target (prisoner). This is obviously different from the city security monitoring. The monitoring head of the city security monitoring generally needs to monitor the monitoring range of more than 100 meters.
Therefore, the application of high-definition surveillance in prisons has always been in a rational and steady development. Because of the application of high-definition surveillance, not only the resolution of the image is required to be high-definition, but also the encoding bandwidth is increased, the storage space is increased, and the media traffic is increased. The cost requirements for network transmission products and storage products must be increased proportionally.
Comprehensive cost and technical factors, when a complete prison is planning video surveillance, it generally adopts high-definition resolution products in the perimeter, outdoors, and public places. In Dwellings, canteens, hospitals, factories and other indoor locations, the main focus is on D1 resolution: First, the monitoring range is relatively small, the monitoring target distance is very close, and a small 10-square-meter room houses 2, 3 cameras. D1 has been able to fully meet the requirements. Second, prison officers on duty are familiar with the prisoners under their jurisdiction. Generally, the prisoner's outline can be used to determine which person is the person. Therefore, considering the price/performance ratio, D1 is used in the interior and non-key areas of the building, not the HD resolution image.
The monitoring point design also fully considers the requirement of no dead-end monitoring, deploys 2-3 monitoring points in the housing, deploys monitoring points at entrances of corridors, corridors, and monitoring areas, etc.; it is located in outdoor public areas such as playgrounds, The prison park walkway also has high-definition monitoring points to be deployed, and monitoring points are deployed in AI building, hospitals, canteens, confinement rooms, and access buildings. Deploy high-definition monitoring points every 50-100 meters in the perimeter. So overall, compared to the previous design of more than 100 monitoring points, the current prison planning basically meets the requirements of thousands of points.
