to achieve the transmission of the video signal by the following aspects: one is the rental of telecommunications operators line, the image signal is a signal of large amounts of data,2013 cctv cameras for the home, to clear transfer each image transmission the band width not less than 300Kbps, one image on rent about 2000 yuan or so,2013 residential security camera, this is clearly uneconomical. The two is its own cable, it is not realistic, because in the current municipal planning, to laying lines in the examination is very difficult, but the initial investment is too large,2013 wireless surveillance camera, in the city every kilometer cost about 10000 to 20000 yuan, the fund was very tense circumstances is clearly uneconomical. Three is through the microwave transmission, only need to place a wireless microwave transmission equipment in the image control point, control is placed at the center of a microwave radio receiving equipment can be, the transmission part of the cost is only equivalent to the cable laying one or two kilometers of costs,2014 cctv camera, so the cost is very low. But the microwave image transmission equipment we use has been in the traffic police border security, has the very widespread application,2014 wireless security monitor, technology is very mature,2014 security cameras video, the quality is also very reliable. In addition to the microwave frequency band used can be flexible and change, can be arranged in special frequency band public security system, but also has a certain ability of the diffraction, used in small and medium-sized city, is very suitable.
overviewCity Road wireless monitoring scheme of
implementation of video monitoring on the road, which in the big city is very popular. It is not only in the daytime, real-time monitoring can realize the road in the night. This is very important for road traffic order management: can save manpower, on the part of intersection and road can realize unattended, do the most effective work with limited human and material resources; also can prevent and control of road traffic accidents effectively the occurrence,2014 security camera warehouse, guarantee people's safety of life and property; video monitoring provides the video data can also processing of traffic accident provides strong evidence and materials.
two, video monitoring system
realization of video monitor itself is not difficult, this technology has been very mature. Due to the characteristics of city road determines the realization of video monitoring difficulty: not like a factory or enterprise, scope is little, only up to a few hundred meters, so the transmission part is very simple, linear shaft video line can be. Monitoring and to realize the city road, range is relatively wide, usually in a few kilometers to tens of kilometers. Coaxial video line is not so far, only a few hundred meters. So the difficulty in the transmission part, how safe, clear,security camera game, low cost (the image may also have sound) returns the command and control center is what we have to focus on the issue.
video surveillance can bring direct visual effect, convenient to you and your organization. It is widely used in various occasions, such as monitoring the warehouse monitoring,2014 cctv camera cost, important traffic arteries and video monitoring and other important position. You can sit in your office, you can see the mechanism of each important occasions your real-time image >
