Q:What's the monitor?

A monitor is a display that acts as an image and converts a video signal into an image.

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:How to invade CCTV surveillance camera

If someone's monitoring is not connected to the Internet, the invasion is not impossible.

Q:Can the engineering monitor and test instrument measure the closed circuit and the network line?

This mainly depends on your engineering treasure function, there are some engineering treasure, powerful, television, telephone, network monitoring can be measured, and some can only measure some of them

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 difference between CCTV surveillance system and video surveillance system?

The difference between a former computer and a current one,

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:The difference between the electronic police and the closed circuit television surveillance in Guangzhou traffic police

Like high-speed exits on the ramp, there are basically cameras (refers to closed-circuit television monitoring), some people in the ramp off the head, want to drop a small car, in many cases will be video, just wait for the money to go.Also, the downtown peak intersection, the solid line change lane (queue) will be taken. But this is not all belong to the random nature of the time will be caught.

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 to distinguish surveillance cameras?

Cameras vary according to classification standards, and can be classified according to the following criteria:1) according to the imaging system divisionAccording to the imaging system, the camera can be divided into PAL and NTSC camera system using PAL camera, camera for many countries, such as Germany, Chinese, Singapore and Australia; using NTSC system mainly in the United States, Japan and other countries.2) according to the imaging device DivisionAccording to the imaging device, the camera can be divided into CMOS camera, CCD camera, DPS camera.CMOS (Complementary Metal-Oxide Semiconductor, complementary metal oxide semiconductor) camera is characterized by low price, low power consumption, fault is a short life, poor sensitivity, easy to noise, for some early video cameras, HD video camera is based on CMOS.
