Q:How to install an indoor closed-circuit TV with a computer

The closed circuit is relative to the opening, and the latter is the television reception mode we usually call the outdoor antenna to receive the signal. Closed circuit is the satellite transmission to the designated user, that is, cable TV mode.It mainly converts the audio and video signals into one radio frequency signal, that is, one channel, so that it can be transmitted in closed-circuit television

Q:Closed-circuit television monitoring system, video installation set what quotasfixed

In a digital communication system, the transmitted signals are digitized pulse sequences. When these digital signal streams are transmitted between digital switching devices, the rate must be completely consistent so as to ensure the accuracy of the information transmission. This is called synchronization".

Q:How to install closed-circuit monitoring?

The front end monitoring device is installed, but the back-end device is installed. The first scheme uses video capture card to install the video capture card into the PCI slot of the supermarket computer, and uses the computer host's hard disk for video storage.

Q:What's the difference between TV surveillance system and video surveillance system?

Q:What does security engineering refer to?

Security engineering is to achieve the use of modern scientific and technological means to achieve security protection process, security products is to serve security engineering equipment. Security projects include building intelligence (building intercom, etc.), video surveillance, access control, attendance, anti-theft alarm, parking management, smart home, room engineering, etc..

Q:How long can the CCTV Monitor keep the video?

In general, embedded hard disk recorders that store images support 16 channels of video input.

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

The quality of the equipment or parts itself. Theoretically, quality problems can occur in all kinds of equipment and parts. But in experience, the quality of the product itself is the most important. It occurs on the decoder, the electric pan head and the transmission parts. It is worth pointing out that some equipment may not appear on the whole quality problems can not be used, but in some technical indicators can not reach the specifications given in the product specifications. Therefore, the necessary sampling must be carried out for the selected products. If it is a product quality problem, the best way is to replace the product, and should not be removed and repaired.In addition, the most common problem is due to improper adjustment of the equipment. For example, the camera after the adjustment of the intercept is very meticulous and accurate work, if not carefully adjusted, there will be poor focus, or in three variable lens defocus occurs when the various operations. In addition, the camera switches and some adjustment knob is in the right position and whether it meets the technical requirements of the system, decoder encoding switch or other adjustable position is correct or not will directly affect the normal use of the equipment itself or affect the normal performance of the whole system.

Q:The CCTV Monitor for hard disk recorders is black and white. What's going on?

If the light enough, then there may be video line transmission problem, first, welding is not good, two is the line resistance is too high.It is also possible that the camera itself is faulty.

Q:What is the working principle of security monitoring system?

The simple answer to you, to understand: if a fixed camera power line, a video line, a video recorder, a head in head position in the camera position, then on the line, if the camera is active with a signal line (like power line), installed in the room on the recorder on the line.
