Q:Computer monitors can be used as closed-circuit surveillance TV, only monitors. If you add a converter, you can contact the camera to see the monitor

Want to know the wiring principle it is very simple, is a computer video, the video output is VGA interface, high-definition digital TV or now generally have this interface, according to the line then, if you want the original display can see, you can buy a VGA one minute (general a two can be a) signal is connected with the TV, if no VGA output, can buy a VGA turn lotus head video output converterTwo is audio, with 3.5mm to connect or 3.5mm to Lotus head line, receive the corresponding audio input on TV or sound

Q:How to install home security monitoring system?

Depending on its complexity, the installation of a general home security system can be done entirely by the homeowner himself. Many of these security systems can be easily purchased online or through electronic stores and specialty stores, and can be installed by any DIY enthusiasts themselves. Installation of home security systems involves the installation of cameras, usually in the passageway or other selected locations. Some wireless cameras work on batteries so that they can work properly during blackouts. But this must have good performance of the battery in order to ensure that the system works properly. Wired home security systems have higher technical requirements for Installers, so that professionals may be hired to help us install them.

Q:Characteristics of closed circuit monitoring system

Closed circuit monitoring system provides remote monitoring and control. According to the relevant national technical specifications, the system should be set up security camera, TV monitor, video recorders (or DVR) and image processor, the user can at any time any tune to see a picture of any remote control camera etc..Closed circuit monitoring system generally consists of three parts: front-end equipment, transmission part, back-end equipment (including control equipment and display equipment).The main components of closed-circuit monitoring system are: camera or image acquisition device, image transmission and control equipment, image processing and display equipment. Closed-circuit television monitoring system of the technical requirements are: the clarity of the camera, the system's transmission bandwidth, the video signal to noise ratio, television signal format, cameras achieve higher quality and operation function, as well as the environment of each part of the system to the extent.

Q:How to install closed-circuit monitoring to connect to mobile phones?

The simple principle is the use of software to monitor you can watch CCTV on the computer, only need to install a subroutine in the computer and run in the background, even if there are people in the operation of the computer and do not see any traces. (unless you see the task manager often!). Then, install the mother program on your cell phone, and turn on the APP on your phone to monitor and control everything on that computer... The biggest premise is that the computer can not be switched off.

Q:What are the common types of CCTV cameras?

The camera is divided according to its shape:1, hemisphere camera; 2, gun type camera, 3, spherical cameraSix, the camera is divided according to the lens:1. Focus camera; 2 zoom camera;13 years of experience with AI technology.

Q:How to choose the transmitter in security monitoring system?

APL, that is, the average image level, many engineers are not too careful or not too familiar with this indicator. However, if such a problem encountered in Engineering: when it comes to some video signal through the optical transmission, when a large area of white in the picture (such as camera glare screen) will monitor the level of jitter, so engineers must not strange. This is because the voop some manufacturers of the APL range is too narrow, when there is a large area of white in the image signal, the DC component of each line in the image signal increases, APL will increase, causing the line sync signal amplitude decreased or lost, the monitor cannot detect the line synchronization and screen jitter. If you need to buy otical if the Pacific security network, recommend a few brands pdh.

Q:What is the working principle of TV wall display in security monitoring system?

TV wall display, general use monitors, monitors, television, as well as splicing screen, splicing screen is divided into DLP, PDP, LCD splicing.Analog surveillance generally adopts video matrix, through the BNC interface on the wallDigital monitoring usually adopts digital matrix through the upper wall of VGA interfaceIf splicing screen is adopted, arbitrary splicing can be realized by splicing processor.

Q:How can the CCTV surveillance video be deleted?

Format the hard disk (all videos are empty)Right main menu - management tools - hard disk management - formatting, hard disk operation, all the video on all deleted

Q:What is the difference between "closed-circuit surveillance electronic police" and "electronic police"?

Closed-circuit surveillance electronic police is the camera, monitored by the manual in front of the surveillance screen. "Electronic police" is a camera and sensor matching, illegal activities are automatically triggered records.

Q:What does weak current integrated wiring mean?
