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:Can the closed-circuit line be a monitoring line?
Surveillance video cable is a kind of wire and cable used to connect security surveillance cameras and real terminals (computers or monitors, etc.) to transmit image data captured by surveillance cameras. Surveillance video cable is a kind of coaxial cable, also called coaxial video line, the letter code is SYV, so it is also called SYV cable or video coaxial cable.
Q:How much bandwidth does closed-circuit surveillance require for remote transmission?
According to the number of road, a road requires a minimum of 500K network bandwidth can be achieved smoothly, you can set the minimum head each 128K stream, that once you see 4 road, a round of visits.
Q:The difference between the electronic police and the closed circuit television surveillance in Guangzhou traffic police
Electronic police: refers to the automatic camera, and to determine whether your car is illegal electronic instruments, are automatically recorded violations of information.Generally used in: red light running, speeding, violation, change lines and so on.CCTV: refers to a camera that can adjust the angle and focus of a camera. It is used to monitor the traffic flow, and to determine the responsible party after the accident has occurred.
Q:How to connect the CCTV special monitor power supply?
CCTV (closed-circuit television) has been used in security systems for many years. CCTV is a reliable and economic deterrent, as well as a good evidence of arrest and criminal charges. Now, most security systems need to use several different security technologies, such as alarm systems, fire detection systems, intrusion prevention and detection technologies, access control systems.
Q:How to install home security monitoring system?
With the development of society and the acceleration of population flow, the security situation is becoming increasingly severe. In today's society, there is a general lack of security. Home is our last port. However, because criminals have sights on every corner of the house, we also need to active protection. As a result, more and more families have chosen to install a home security system to protect their homes. In this paper, Jane family security monitoring system selection and installation.
Q:What are the security monitoring TV walls required?
The front end uses the network camera, then the surveillance video frequency acquisition has not been a problem.The 21 points are in different places, and the front end and the back end are all connected by network devices, of course. Don't you have a wiring problem?. Is the distance between the 21 points very far?Each video signal needs to be on the wall, it is best not to use the TV, with professional LCD monitor will be better. In addition to security monitors, you also need screen splitter, TV wall rack, and video recorder if you want a hard drive.
Q:What is security system engineering, please?
The control layer is the core of the whole security monitoring system, and it is the most clear embodiment of the system's scientific and technological level. Usually we have two control modes analog control and digital control. The simulation control method in the early stage, the console is composed of controller or analog control matrix, which is suitable for small local security monitoring system, this control method has lower cost, the failure rate is? But for the large security monitoring system, this way is complicated and no price advantage, then we it should be the choice of digital control. Digital control is the industrial computer as the control core of the monitoring system, it will complex analog control operation into a simple mouse click operation, the huge analog controller stack shrunk into a computer, control cable will be complex and huge number into a serial line. It can change remote monitoring into reality and provide possibility for Internet remote monitoring. But digital control is not so perfect, the price of the control host is very expensive, the waste of modules, the system may collapse, the crisis is still lagging behind and so on.
Q:How to choose the transmitter in security monitoring system?
Video bandwidth is an old growth issue. The video bandwidth is not enough, the detail of the monitor screen is not clear enough, the horizontal resolution is low, and even the color distortion or video loss is serious. Because of the importance of video bandwidth for image quality, some unscrupulous vendors intentionally exaggerate the video bandwidth of the product to deceive customers. For example, a digital video optical transceiver manufacturers claim their video bandwidth is 8M, but the release of video sampling frequency is 12.5M. According to Nyquist's law of sampling, the signal should be sampled at least two times as much as the signal frequency. So now, the transmitter manufacturers the theory of video bandwidth in any case can not be more than 6.25M. Obviously, this is a lie to exaggerate the quality of cheating customers, so that no business reputation vendors should not consider the scope of the purchase. But not all customers can accurately identify vendors lie, for general contractors and users, by observing the details of the image, you can rough judgment of the device's video bandwidth.
Q:How to make closed-circuit monitoring into remote monitoring?
On the router, map the IP address and port number of the video recorder (http/web port, mobile port, transmission device port and other corresponding network access ports).
The company mainly in the security monitoring, anti-theft alarm, intelligent, LCD products. We have set up the development of the factory, the production of cable camera, wireless camera, MINI DVR, and obtain the general agent of five industry brand, and a number of manufacturers of products to a regional distributor rights. Our innovative products, variety complete, the future will continue to develop new products more intelligent fashion.
