Confidentiality of shared EIP in prison monitoring system applications (1)

System overview

According to prison monitoring and control system for specific requirements, the establishment of Web-based multimedia monitoring programme, meet the prison's own security and security needs.

At the same time meet the prison information sharing within the computer, Office Automation for prison computer.

Programme design itself takes full advantage of the prison itself high-tech facilities and new computer network of rich resources, application-based multi-media monitoring technology, digital video surveillance for the control and management, and control video image processing into computer networks unified management.

Monitoring system uses a DVR (that is: DigitalVideoRecorder hard disk records) the monitoring system to record the monitor image, you can easily achieve network remote transmission monitor image screen displays. Considering that the prison the particularity of computer network security, network monitoring and control system, designed to be relatively independent prison information network small LAN/relative prison information independent of the network segment.

System principle

Over the years, numerous security monitoring industry manufacturers on P4-class industrial CPU card available, always be the most ardent attention.

Because Pentium-4 industrial CPU card, video monitoring, is the inevitable trend of DVR also necessarily promote video surveillance field to a higher level of development. At present the monitoring system, using the MPEG4 compression mode, fully compatible with TCP/IP network with a more robust performance.

1. monitoring the front-end device AV (audio video) signal transmission through the video cable to the system control host/control extension of AV input, alarm signal transmission to the alarm input.

System control host/control extension with digital multi screen display and linkage alarm, lighting, electric gate, audio and video synchronization acquisition, hard disk recording monitor images, remote radio monitoring image, listening/speaking and other functions.

2. control extension can also be transmitted via a network remote monitoring, remote monitor image and control.

3. control extension/host as video server, local control over image for digital picture display/TV wall display.

Remotely monitor and control the monitoring device, the control of the Ext frontend/host local hard drive to record the monitor image and linkage alarm, lighting, electric doors.
