The detention center system is a system that requires high security and high stability. The main business functions of the system include the following: First, the monitoring and management of detainees in warehouses, corridors (or stairwells), public activity areas, perimeters, etc. Second, the monitoring and management of foreign personnel in the restricted areas such as the arraignment room, the lawyer interview room, and the family visiting room; the third is the management of the contents of the entrance and exit of the staff, the patrol and attendance, etc.; and the fourth is the management personnel. And its superiors provide convenient management tools.
The system uses a variety of practical and applicable technical means to build a system. It uses a front-end information acquisition system and terminal equipment to build a sound and video two-way transmission control system. The back-end attaches to the established centralized control center and integrates all collected data information. Together, unified scheduling management. It mainly contains the following contents:
1. Audio and video monitoring system This subsystem mainly performs audio and video signal acquisition and remote control.
In order to ensure the security of the warehouses, the officers can see the activities of the prisoners in the warehouse at any time and at any place and require that surveillance cameras be installed in each warehouse. Due to the strict monitoring requirements of the detention center, images of corridors, ladders, public activity areas, perimeters, and main entrances and exits need to be monitored at the control center in real time. Therefore, cameras must be installed to monitor these locations.
In fact, the image monitoring of the complex people's environment light in warehouses is not enough, and it must be combined with sound monitoring. The police can control the real situation in the warehouse. Therefore, it is required to install the monitor in place in the warehouse. The warehouse monitor and the warehouse camera correspond one to one, and the control center police can monitor and monitor a certain warehouse through audio and video synchronization switching. Similarly, the arraignment must also have a recording function so that images and sounds are recorded simultaneously for future reference.
2. The alarm system considers that video surveillance will have limitations in certain circumstances. Therefore, the alarm system should install alarm devices in important positions such as warehouses and perimeters, and can realize real-time detection of front-end alarm devices in the main control room. And the system displays the location of the alarm point with sub-zone indicator or electronic map, accompanied by sound and light warning. The riot-prevention emergency button is installed in the warehouse, and in case of emergencies and special requirements, the detained prisoner can press the emergency button to call the police or police on duty.
Perimeter alarm uses two kinds of protection technologies. A high-voltage power grid is installed at the top of the wall, and an active infrared dual-beam detector is arranged on the inside of the wall. The alarm signals of each zone can be linked with the local camera. Once the alarm occurs, the corresponding camera image will be automatically recalled and displayed on the console monitor.
3. Entrance Control System (Access Control)
Access control and management through credit card. Detention centers are the places where prisoners are detained. Therefore, the control of doors and doors is an important part of the entire prison security system. The detention center requires that the access control system not only meets the general functional requirements of the general access control system, but also must have more complete functions, such as one-way credit card (general access control function), two-way credit card (requires all cardholders to swipe in and out). Anti-submarine back (if a certain card is swiped into the door, the card will be sneaked out without swiping the card, the card will be forbidden by the system at the next time the card is swiped in and the card will be interlocked in and out), and card swiping video (every time the credit card is linked to the video capture card reader Face image, can effectively prevent others from stealing legitimate cards and committing crimes, and guarantee the legality of credit card users.
4. From the perspective of scientific management, the broadcasting system guards all ideological education activities, morning exercises, announcements, and emergency broadcasts for prisoners detained. A complete set of broadcasting systems can fulfill all the above requirements. The broadcasting system should be divided into two. Part - warehouse broadcasting and public area broadcasting. The warehouse broadcasting should have single, cluster, partition, and all warehouse barrage broadcasting functions. Public area broadcasting is mainly set up on playgrounds and perimeters, and district management must be implemented.
5. Intercom patrol system In order to make the management of the detention center more humane, two-way walkie-talkies can be considered in the warehouse. When the prisoner presses the emergency button, the control center officer initiates the intercom system to talk with the warehouse to provide conditions for emergency handling. In addition, in order to avoid supervision loopholes during family visits, the prisoners and their families can be separated by glass walls and communicated through the intercom system to prevent possible physical contact between the two parties. The intercom system must provide recording capabilities.
Because of the special nature of the detention center, the police officers are required to conduct day and night inspections of the doors in each warehouse and prison area. The patrol system has two kinds of off-line and on-line type, offline type does not require wiring, and is inexpensive and easy to expand, but it does not have the real-time nature of uploading patrol information. The online type can upload patrol information in real time, but it is more expensive and less convenient to expand because of the need to lay cables. However, whether online or offline patrol data can be stored and queried, various reports can be generated and printed.
6. The attendance system's electronic attendance function is an integral part of the modern office. Therefore, it is required that the access control point in the office area can realize the attendance function. The attendance information can be transmitted to the central management host in real time, or it can be temporarily stored in the access controller. Attendance data can generate various reports as a certificate of assessment.
In addition, pay attention to the linkage and integration of each system. Now, there have been some integrated products. If the performance is stable, it can be considered for use, which makes the system control more convenient and also saves the system cost.
