Overview of Digital Remote Monitoring System

Computer digital compression monitoring system equipment composition map

Just a computer, no special staff. This monitoring system eliminates the purchase of a large number of monitors, video recorders, video switchers, matrices, video tapes, and the like. It also eliminates the cost of personnel on duty and the replacement of videotapes, which greatly reduces the workload. Achieve the miniaturization of the equipment, all-weather work, unattended, remote control, image input query and other functions. Achieve fully automated operation, without special personnel on-site duty, even if there is no computer experience, just turn on the power, you can perform unattended, automatic monitoring. The staff only needs to operate on the computer keyboard to understand the situation of the monitoring point, and can also extract images that have been previously recorded.

The system can also install automatic control PTZ, the camera automatically zoom, variable pitch, to adapt to different needs of different environments. When monitoring at the same time, it is also possible to use a television to monitor the magnification of any of these screens. Due to the large capacity of the computer, images can be recorded for a long time. The 30G hard disk can retain all images for about one week. If you do not need to retain images, you can also automatically cycle through them. Expand hard disk capacity to record longer images. It is more convenient and cost-saving than ordinary camera recording. It occupies a small area and is cheap.

Due to the digital compression technology, the image signal output to the outside is a digital signal. This signal has strong anti-interference. Without losing the signal, the image quality is high, and image transmission can be performed through an ordinary telephone. This is not possible with the radio frequency image signal of the original monitoring system. Can store images. The digital remote monitoring system automatically digitally compresses the image picture recorded by the camera on the hard disk of the computer. Without the stop buffering technology, the hard disk of the computer is automatically cycled. It is used month after month, year after year.

On a computer screen, four, six, or sixteen camera editing, processing, retrieval, freezing, zooming in, zooming out, and picture processing can be simultaneously displayed in real time.

The equipment of this monitoring system is fully functional. First of all, in the event of an emergency, there is no need to immediately press the alarm button. After the time is up, the alarm is started (time can be set). This system has recorded and stored all the contents before and after the event on the hard disk. Second, the system also has security registration settings for crimes committed against insiders.

The system's software provides you with powerful image-enhancement features for correcting images with inaccurate focus, unsatisfactory brightness, low-contrast images, or colors with non-standard images, thus saving camera zoom focus And cost (available cheap camera). If you combine the monitoring system with the transmission system to use the telephone line to achieve off-site transmission, the daytime monitoring system selects and monitors the camera capture content in the field; if the alarm input is triggered, the system will automatically generate the on-site image window. Under normal circumstances, the remote transmission system can transmit voice and video images at the fastest speed through the network, standard telephone lines, and ISDN data lines. It allows monitoring of four sites at the same time and can control the movement of the front-end head .
