The construction of a complete, integrated, reliable, easy to operate, security system, make it as an organic whole of the whole prison/detention center monitor and management, and can easily access the prison intelligent management system. For prisons, construction of comprehensive intelligent system, through to the science and technology to the police, with the help of science and technology to improve the management level is the goal. In the whole intelligent weak current system, the system involved many, for the construction unit in the whole project system architecture, system integration reflects the management thoughts in prison. This system is mainly composed of the front camera, transmission, centralized control, display, storage, system composition and so on. Monitoring center focused on the video monitor system, alarm system for unified management and operation, and as a command center for all kinds of scheduling, at the same time in the gate guard room set alarm control end, so that the flexible cloth, abandoned. Installed in stairwells, and the first floor hall room intelligent anti-theft detector, in non-working time (or actual) need time for protection, once someone is illegal activities, can trigger the alarm, the alarm signal to the control room and the guard room, send out sound and light alarm, at the same time according to the actual need for alarm real-time video scene (visual) by adding infrared lamp at night. Greatly reduced the workload management, improve the management level.

2. In the central control room, alarm system and digital monitoring equipment organic connection, in addition to the implementation of alarm detection function, at the same time realize the alarm when triggered various linkage function, such as start video, open emergency lights, start a light flash and other called response;

3. In the guard room through flexible cloth fortification control client machines for operation, through the display monitor the important position of the monitor image at the same time (optional).

Any IP online computers can bring up any front-end surveillance images.

The camera selection requires consideration of practical application, the reasonable selection.

3. System design principles

We will be in line with the attitude of sincere and earnest, combined with years of experience in design, construction, according to user requirements and the actual needs of the prison management, using the mature technology, provide a feasible design scheme.

4. System specific implementation plan

1. The system is more complex, the key of the design, first is to determine the installation position of the camera's specific environment, and the site environment to choose suitable for the front of the camera and the main control equipment, in order to ensure that monitor the effect.

2. System requirements have alarm linkage function, reserved alarm linkage interface, can be simple and alarm detection system docking, realize all kinds of alarm linkage function, and the video monitor combine to form the three-dimensional space, to prevent the monitoring scope to a higher safety factor.

3. The system supports remote access and IE browsing capabilities.

4. System requirements have control rooms centralized management and control function, make the system management to achieve an orderly from top to bottom.

TV wall part of the system as a key part of the whole system, total control room received signal is compressed digital signal processing, through digital matrix host to achieve this function is a key part of the whole system.

5. Equipment selection:

Gateway: 1. The prison due to monitor the position is sure, consider not enough light, so the adopts fixed point and infrared night vision camera, effectively complete required tasks into the mouth of monitoring products.

2. The prison wall corners: on the one hand to the camera to do waterproof, dustproof, pollution prevention and protection, on the other hand can beautify the monitoring points in the look and feel of the product, can meet the requirements of practical aesthetics and can better fit the correlation alarm, suggest that choose the infrared night vision intelligent high-speed ball, can use its precast an alarm function, to realize automatic alarm after the purpose of the alarm is rotated. In order to improve the accurate identification of the camera alarm azimuth, recommended to the alarm detector, to refine the alarm position.

Room 3. Prisoners: because the scene no light at night, so in order to ensure normal monitoring at night, and considering the concealment (negative feelings of reducing staff to monitor equipment) and prevent destruction, so using high-resolution riot hemisphere infrared night vision camera. The camera's features are: camera, camera, infrared lamp, hemisphere shield integration; High integration, small size, beautiful hidden, installation is simple; Using SONY movement, image clarity, color saturation, reductive degree is high; Built-in photosensitive switch, automatic open lamp, compensating for the camera light source.

4. Corridor, restaurants and other places of activity: because the scene no light at night, so in order to ensure normal monitoring at night, and considering the concealment (negative feelings of reducing staff to monitor equipment) and prevent destruction, so using high-resolution riot hemisphere infrared night vision camera. The camera's features are: camera, camera, infrared lamp, hemisphere shield integration; High integration, small size, beautiful hidden, installation is simple; Using SONY movement, image clarity, color saturation, reductive degree is high; Built-in photosensitive switch, automatic open lamp, compensating for the camera light source.

5. Monitoring and control system for 100 points, we choose eight stage 6 road embedded real-time digital hard disk video host, all features are: the h. 264 compressed format (international) is the most advanced compression techniques, more save disk space; Audio and video synchronization acquisition, outstanding quality, sound quality is clear; All display, video speed of real-time; System fully functional, product maturity, high stability, has a long period of market and a large number of users; System more friendly interface, simple to set up; Support powerful network remote monitoring function, less bandwidth; Has a variety of language version software, convenient use different user groups. All performance indicators through the national ministry of public security testing and certification (specific function please see digital hard disk recording) in detail.

6. The hard disk volume according to the continuous recording 16-way cameras 24 hours a day, the video quality CIF (250 million/hour), video footage reserves calculation, 4 weeks for each special DVR hard disk video recorder need to configure the 4 pieces of 1000 g hard disk. Due to hard disk footprint and set the image quality and also monitor the activity of the picture, so here to calculate the amount of hard disk is only reference. (in order to save the hard disk footprint, can use video mobile video mode, the perception that a mobile launch video object, no mobile video.)

7. The monitoring center

Total network video monitoring center adopts centralized monitoring management system centralized monitoring management system can be divided into network monitoring center, the local monitoring, and the client. It is an integrated application platform based on network operation. Suitable for cross-regional, across a network of network mode. The center of the monitoring center through the network management server to centrally manage and monitor all of the host configuration system. All local monitoring of audio and video data and alarm data collected will be promptly returned to the network through the network video monitoring center workstation or client, network center can look at all the remote tuning local end video monitor, image resources and network center can also be based on specific needs to set the audio and video data and alarm data is centrally stored in the center of the network video workstations, or stored in the local monitoring on the hard disk video recorder. When the system of video data requires high security, also can store the data at the same time in the center of the network video workstations and local monitoring on the hard disk video recorder. The current end alarm equipment acquisition to the alarm information, alarm signal will be feedback to the network monitoring center of electronic map/alarm host, through the electronic map, can intuitively reflect the monitoring network image data. For ordinary client and IE browse in terms of the client, can be in the center management server within the assigned permissions for different levels of operation, when the need to adjust the real-time video data, through the video images of the workstation forward capability to implement each client remote access to the front-end images, so the front main control device to upload images, not repeat network bandwidth, ensures the stability of the image to upload, make the front image transmission speed and image quality is not affected by the number of the client.

Network monitoring center equipment by the center management server, video workstations, electronic map/alarm host and client television (digital TV wall).

Video and automatic video Settings, and so on. Through center management server can at any time according to need to add, delete, modify the front set parameters of the main control equipment.

Video workstations, main connection network video server and front-end equipment such as hard disk video recorder, video workstations to network video server for storage, transmission of audio and video signals and alarm signal and can use the video footage of hard disk video recorder for points. At the same time, provide users with all remote video image display, video and yuntai control, also for other network client video source, responsible for forwarding sound and video images.

Electronic map/alarm host is an important part of video surveillance management system, in combination with electronic maps, can accurate will alarm information point to reflect on the map.
