The location of the road signal lamp installation
Surveillance poles are also called surveillance poles, which are columnar brackets used for outdoor surveillance camera installation, mainly for traffic roads, crossroads, schools, governments, communities, factories, border defenses, airports and other places where surveillance cameras are needed. The use of monitoring poles improves urban safety precautions and is an effective guarantee for residents' lives. In the process of video surveillance installation, the selection and installation of the monitoring pole is also very important. It is suitable for environmental requirements and the correct installation of the monitoring pole can make the surveillance camera play a better role.
The selection of monitoring poles needs to consider environmental factors:
(1) In principle, the distance between the upright point and the upright point is not less than 300 meters;
(2) In principle, the closest distance between the position of the pole and the monitoring target area should not be less than 5 meters, and the longest distance should not be greater than 50 meters, so as to ensure that the monitoring screen can contain more valuable information;
(3) Where there is a light source nearby, give priority to the use of light source. But pay attention to the installation position of the camera should be in the direction of light;
(4) Try to avoid installing in places with high contrast. If installation is necessary, consider:
① Turn on exposure compensation (the effect is not obvious);
②Using fill light;
③Set up the camera in the underpass outside the entrance and exit;
④Set a little bit inside the channel.
(5) The position of the pole should be avoided as far as possible from greening trees or other obstructing objects. If it is necessary to install, consider avoiding the obstruction of trees or other obstructions, and leave space for the future growth of trees;
(6) Pay attention to the survey, try to get electricity from traffic police signals, street light distribution boxes, governments, larger enterprises, and institutions (such as government departments, bus companies, water supply groups, hospitals, etc.) to facilitate coordination. Improve the stability of electricity. Try to avoid small business users from getting electricity, especially for civilian use.
(7) The gun camera installed on the side of the road, pay attention to reverse shooting of pedestrians, and the facial features of pedestrians passing by in the non-motorized vehicle lane.
(8) The camera installed at the bus station should be arranged as far as possible in the direction of the rear of the vehicle, avoiding the headlights of the vehicle, so as to capture the characteristics of the people on the bus.
