Q:Can the engineering monitor and test instrument measure the closed circuit and the network line?
Yes, you can test the website or video line
Q:Is there any difference between a monitor and an ordinary monitor?
Input signals are different: monitor input AV analog video signal, computer monitor input RGB tricolor VGA signal.The resolution is different: the average color monitor is usually 420 or 480 lines, and the computer monitor is at least 800*600 resolution.Radiation levels are different: color monitors generally do not have radiation protection, and computer monitors must have radiation detection, certification, or the use of liquid crystal display, there is no radiation.
Q:What is the difference between CCTV surveillance system and video surveillance system?
It's the same in broad sense, but in a negative sense, the equipment is different.
Q:Can the closed-circuit line be a monitoring line?
Closed-circuit cable television also called cable TV signal line line, closed-circuit television signal is divided into core and shielding layer of two parts, the middle of that hard root as a signal, while the outer layer of the mesh wire core and aluminum foil as the signal shielding layer, played the role of anti-interference.
Q:How can the CCTV surveillance video be deleted?
Hard disk recorders can not be deleted or deleted selectively, formatted only on hard disks, or new video files automatically overwrite old video.
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:Common faults in closed-circuit television monitoring and their solutions
The quality of the equipment or parts itself. Theoretically, quality problems can occur in all kinds of equipment and parts. But in experience, the quality of the product itself is the most important. It occurs on the decoder, the electric pan head and the transmission parts. It is worth pointing out that some equipment may not appear on the whole quality problems can not be used, but in some technical indicators can not reach the specifications given in the product specifications. Therefore, the necessary sampling must be carried out for the selected products. If it is a product quality problem, the best way is to replace the product, and should not be removed and repaired.In addition, the most common problem is due to improper adjustment of the equipment. For example, the camera after the adjustment of the intercept is very meticulous and accurate work, if not carefully adjusted, there will be poor focus, or in three variable lens defocus occurs when the various operations. In addition, the camera switches and some adjustment knob is in the right position and whether it meets the technical requirements of the system, decoder encoding switch or other adjustable position is correct or not will directly affect the normal use of the equipment itself or affect the normal performance of the whole system.
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:How to invade CCTV surveillance camera
If someone's monitoring is not connected to the Internet, the invasion is not impossible.
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.
