Q:What's the reason for the closed-circuit surveillance image?

The reason for the poor contact of video lines or the equipment itself,The problem of external surveillance probes or environmental factors

Q:The difference between video surveillance system and CCTV system

Popular point says:CCTV system: multi finger monitor system has the duty type, by 1 or several people operation and monitoring, to directly observe and report all kinds of consolidation area, monitoring system to achieve some goal to do.Video surveillance system: Currently, all kinds of surveillance systems based on image recording are popular in the market, which mainly realize the scene playback, easy to find problems and solve problems.

Q:How to install closed-circuit monitoring?

First determine the number and location of the installation of surveillance cameras, hard disk recorders use wire number, number of parameters, and determine the corresponding parameters of the equipment list, to the nearby market to purchase the list of equipment installation technology

Q:Closed circuit monitoring system password cracking

It depends on whether you are using the acquisition card or the hard disk video recorder DVR. If it is a collection card, you just need to remove the previous driver and software and reinstall it! DVR can only be restored to factory settings

Q:CCTV can generally monitor how far it is?

Storage time: according to the size of the hard disk, just like a cylinder, the cylinder is large and the water is small. It is also different from compressed format, and the file size is different.

Q:What is the initial password for the computer monitor?

The monitor is the standard output of the monitor system. With the monitor, we can watch the image sent from the front. Monitors can be divided into two colors, black and white, with sizes 8, 10, 12, 15, 17, 19, 20, 22 inches, and 22 inches in common use. The monitor also has the resolution, which is the same as the camera. The number of monitors should be matched with the camera in practical use. In addition, some monitors also have audio input, S-video input, RGB component input, etc., in addition to the audio input monitoring system, the rest of the functions are mostly used in image processing.

Q:What is the simple composition of the intelligent room monitoring system?

In brief, the basic configuration of each subsystem consists of three units: front-end, transmission, information processing / control / display / communication. Different subsystems, the specific content of their three units is different

Q:Common faults in closed-circuit television monitoring and their solutions

In a monitoring system into the commissioning phase and commissioning phase and after delivery, there may be such a failure phenomenon, such as: normal operation, system is not up to the technical index, the design requirements of the overall performance and quality is not ideal, that is some soft faults". These problems are unavoidable for a monitoring project, especially for a complex and large-scale monitoring project.

Q:What is the difference between closed-circuit monitoring and network monitoring?

Network video monitoring system used for flexible (mainly by IP broadband network), multiple users can share a set of center control platform, user input, easy to use, users can browse and remote control, any Internet where principle can browse and control. It also introduces many new technologies (such as digital image recognition technology), to make up for the lack of traditional video surveillance system, provides the value-added service ability, expands the function and scope, improving the performance and intelligent system.

Q:How do you record everything monitored by the CCTV Monitor in your computer?

The term "closed-circuit monitor" is not appropriate!
