For the surveillance cameras , the quality of the location is directly related to imaging equipment. Therefore, many effects users will install surveillance cameras to monitor the position considered the primary reference. However , they overlook a very important point : surveillance cameras are not a panacea , the choice of installation location on , it also has its own requirements. The first is at the installation location , in order to enable the camera to avoid interference with the surrounding environment, to achieve a better camera and survival effects. When installed in an indoor environment , we want to ensure a high degree of equipment as much as possible not less than 2.5 meters, and in the outdoor environment, we have to monitor the device being in more than half from the ground three meters in height. Otherwise , both to protect themselves from the camera , or device monitoring perspective, will have many negative effects. Only after taking into account these fundamental issues , the angle is the aspect of our consideration. For network camera , it 's clearly better than the line to set up the way traditional analog devices richer . However, no matter what kind of transmission is the use of interference is one of the issues we have to pay attention . Especially for video signal transmission cable , the signal line and the power transmission wire in the same direction during stringing undoubtedly taboo , more convenient not to both the construction and the transmission line in the same tube . Even if the environment is limited , it can not be both separated , they should ensure that at least half a meter spacing . Only such a plan , in order to better avoid magnetic interference effects for video transmission . As for the use of wireless signal transmission equipment , although some of the limitations fewer lines . But the camera itself but also the surrounding avoid magnetic interference sources . While ensuring the camera and insulate the ground . In addition, we also need to avoid the line of work for the head impact and obstacles.
The use of surveillance cameras at night , in order to avoid reflections and shadows , often require lighting, you can use infrared lights to replace ordinary light bulbs. However, the user must use black and white surveillance cameras and network video server monitoring with infrared lighting equipment , because black and white surveillance cameras are more sensitive to infrared light-sensitive , and color infrared surveillance cameras can not play functionality . Today, there have been numerous cameras are beginning to use wide dynamic features to enhance the environment in the backlight imaging capabilities. However, this does not mean the camera can continue to complete the work in bright light environments. Because in bright light shining, the camera is likely to cause direct glare is difficult to locate the exact image of normal , eventually causing permanent discoloration color filter on the sensor chip , the camera streaks in the monitoring image. So, if you can, we try to make the camera in a " smooth light " model , but in any case , we have to avoid glare prolonged direct stimulation of the camera lens .
In addition to some of the aspects mentioned above complete , some auxiliary equipment installation specifications of the camera is what we must not ignore the link in the construction . For example, let the camera pan and tilt mounting position , racks and other equipment meet the design requirements, installation should be smooth solid, easy operation and maintenance . Back and sides of the rack away from the wall to meet the maintenance requirements ; necessary , we have to install the protective cover of the camera or the temperature control device , and so on . For connecting link with complex lines , we should also indicate the usefulness of each line and the characteristics for future maintenance. All along, the bandwidth limitations are a major reason for the expansion of network monitoring difficult . It is also because of this factor , resulting in a polarization of network users for a long time - the strength of the use of self-built network , but not the strength of the user or only to endure the slow transmission , or to find another way out. However, with compression technology continues to improve , and optimize the network environment. Network monitoring is also becoming increasingly better living environment together . However, if the general public in order to achieve complete network users to better monitor the case, an advanced performance processing terminal apparently also indispensable. On system performance, we should try to adopt , such as linux or win7 the most advanced treatment systems , and has the advanced CPU, a relatively large amount of memory and graphics cards , etc. , to be able to make our equipment will play a more comprehensive imaging results . In addition, in our system if there are other auxiliary alarm facility , then pay attention to their compatibility with the system , focusing on the stability of the device itself to work in the current environment, we also need to focus on during erection and commissioning of the equipment .
Mentioned above, the key areas of concern is when we need to set up a simple network monitoring system. Compared to some of the large, complex monitoring system, apparently more simple and intuitive in these areas . However, from a critical perspective, these cameras can be said to affect the quality of the lifeline link is absolutely not be ignored. Only if we seize these important but easily overlooked when the elements mentioned above , it may enjoy a more efficient and convenient network monitoring results.
