The remote monitoring system consists of the monitoring front terminal system, image transmission subsystem, central control subsystem and remote image user system. The image remote monitoring system is a set of digital video remote monitoring system that is completely based on the network and designed with B/S structure, which is a high-level remote monitoring system in the industry at present.
The terminal system before remote monitoring is controlled by the network video camera Or ordinary camera and decoder. The webcam can directly convert the image to IP signal without MPEG4/IP converter in the transmission part. According to the needs of the site, infrared cameras and alarm equipment can be installed in the front end to meet special experimental needs.
The image transmission subsystem is composed of MPEG4/IP converter and campus broadband, and can also be directly connected to Internet using ADSL and other devices. MPEG4/IP converter converts images received by ordinary cameras into IP packets, which are transmitted to The server 。 In this way, the existing campus broadband network can be used instead of laying video cables, and the transmission of images is not limited by distance.
The remote monitoring center control subsystem is composed of digital video monitoring service software and PC server, which provides remote video image publishing and user management functions. The desktop control system consists of the user's computer, without installing any software, as long as you use the browser and enter the corresponding user name and password, you can access various functions of the system.
Image format and network traffic: The system uses MPEG4 encoding, with a resolution of 704 × 576 (PAL) 25 frames/second, and can provide various high-quality video images from 28.8kbps Modem to 3Mbps.
Control function: the remote monitoring system can control the aperture, focal length, depth of field and other operations of the lens. The pan tilt can be controlled in all directions. The system can carry out all-round remote control over the rotation of the PTZ from top to bottom, left to right.
Scalability: The system adopts B/S mode and three-tier structure distributed design, which can easily expand the system by deploying multiple video servers to increase the number of monitoring points supported by the system.
Availability: The laboratory network video monitoring system adopts the "B/S structure", and the client interface runs on the Web browser, so that users can conveniently log in to the system from a remote location and use all the functions of the system. Reasonable system division, optimized function layout, full Chinese operation interface, flexible mouse control of monitoring screen, all of which provide users with powerful system functions.
Interoperability: the system provides standard development interfaces.
