Q:What do you need to add an ordinary home computer to a closed-circuit monitoring host?

It is necessary to choose a larger hard disk. If there are not many surveillance points, the video will only last about a week, and a 320G or 500G drive will be enough.4, since it is a home computer, in the video, it is better to specify a video disk path, more convenient.

Q:What are the reasons for the absence of signals in the closed-circuit monitoring system?

If you say yes, the extension cannot display the image or show no signal, and the host has an image with a signal. That's the network or the problem of setting up the extension software.It's about to be tested. If you have any questions, you can ask again.

Q:I'd like to have a closed-circuit monitoring at home

Camera, one, power line, video line, 2 BNC connectors, a hard disk video recorder, a 160G hard disk

Q:Characteristics of closed circuit monitoring system

The building closed circuit monitoring system scheme, the building closed circuit monitoring system scheme and the building closed circuit monitoring system scheme, the closed-circuit monitoring system widely used in all sectors of our country is mostly analog.Its main features are as follows: the system adopts matrix host control, monitors the front end target through the television wall, and uses long delay analog video recorder to record and replay;The main drawback is that when video data needs to be backed up for a long time, a large amount of video tapes are needed, which consumes a lot of manpower and material resources, and is inconvenient to operate during the video retrieval. Therefore, the hard disk video recording system based on digital storage technology has been developed for several years. So far, the technology has been fully mature, and it has solved the difficult problems of traditional image storage and playback.

Q:Now the design institute design closed-circuit monitoring, how to still use analog monitoring ah?

The difference between analog monitoring and digital monitoringIn accordance with the principle of economic application and stability, designers of design institutes recommend the use of analog signal monitoring system. Simulation monitoring is to generate analog signals, through the acquisition card or hard disk recorder converts analog signals into digital signals stored, or by the more primitive way is through the video and other media to store it.

Q:What is closed-circuit, such as closed-circuit surveillance, closed-circuit television, and so on

1 、 camera (transformer, support) - (video line, power line, control line) - hard disk recorder - display2, the camera (transformer, bracket), video line, power line and control line - (equipment box, optical transceiver, optical fiber, optical fiber jumper) (power line) - Optical - VIDEO - line distributor - matrix (DVR) - display (TV wall)

Q:Security monitoring, the monitor is too far away from the hard disk video recorder, how to answer?

First of all, if you want to connect to the security room through the VGA line, this is not advisable. Because the VGA line needs to be made to order, and the quality of the VGA line is uneven, the quality is good to 10 yuan per meter, it is estimated that no one will order 100 meters, so many, at most 20, 30 meters only.

Q:How to distinguish surveillance cameras?

In addition to the traditional network camera camera all the image capture function, the machine is built-in digital compression controller and a WEB based operating system (including Web server, FTP server, etc.) makes the compressed video data encryption, through the network (LAN, Internet or wireless network) sent to the user terminal to the network. The camera to access remote users can use standard PC on their web browser or client software, real-time monitoring of the target site, and the image data stored in real-time, also can through the network to control the PTZ and camera lens, omni-directional monitoring. Some network cameras also have other functions, such as voice intercom, alarm input, relay output, mobile detection, analog video output and SD card local storage video data and other functions. The formula is represented as follows: IP, Camera=, single path DVS+Camera.

Q:In security surveillance, what is the difference between a hemisphere camera, a gun camera and a ball camera?

The biggest difference between the ball and the top two is that the ball can be controlled by the control keyboard. It is usually installed in the large hall which needs to be monitored and has large outdoor area. The general bolt and the price of almost half. Cheap point on a few hundred, and the good will be two thousand or three thousand. But the ball will be very expensive, made thousands of good brand, will reach two or three million taiwan.

Q:What does weak current integrated wiring mean?

Comprehensive wiring is simple, that is, wiring, in general, is laying network lines, the use of ultra 5 or 6 line cable;
