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

Install the transmitter should apply the PDH quota, because the transmitter is E1 signals converge into optical signals equipment, first apply the machine frame, then apply the TSY2-001 quota, quota TSY2-002/TSY2-003 interface disk, finally use the test system channel test quota TSY2-046--TSY2-050.

Q:What's the monitor?

Monitor:Is a closed-circuit monitoring system (Closed-Circuit TeleVision, referred to as CCTV) is an important part of the display part of the monitoring system, terminal equipment monitoring system, monitoring personnel serves as the "eyes", but also for the subsequent investigation plays a key role.

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

Monitoring requires encoders, decoders, storage, display devices, and so on.If you need to connect to the TV can extract the files, then buy a small hard disk recorder machine, plus a special small camera.

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:What's the difference between a wireless surveillance camera and a wired surveillance camera?

Surveillance camera security system, the current image generated mainly from CCD camera, CCD charge coupled device (Charge Coupled Device) for short, it can be changed into light charge and charge storage and transfer, can also be stored charge to take the voltage change, so it is the ideal camera components. The CCD camera is formed with small size, light weight and not affected by magnetic fields, has the characteristics of anti vibration and impact is widely used.

Q:Is it okay to use CCTV for surveillance cameras? Is video line the same as closed route?

It's not the same thingMonitor line model: SYV75-5, -3, usually blackCable lines: SYWV75-5, usually whiteThe same brand with the specifications of the monitoring line, more expensive than cable TV line

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 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:What does weak current integrated wiring mean?

Visual intercom system and closed-circuit television monitoring system, if the IP structure is used to connect, you can use the network of integrated wiring;
