Surveillance camera operation steps and precautions
Surveillance camera operation steps and matters needing attention Surveillance is generally divided into analog cameras and network cameras. The installation of the webcam is relatively simple. After the webcam is fixed, connect it to the router with a network cable. The router must be able to access the Internet. Use another computer for monitoring. Just follow the instructions given by the manufacturer to set it up. This is generally used in homes or small supermarkets. 1. Precautions for installing surveillance cameras: 1. The camera should be installed in a place near the surveillance target that is not easily damaged by the outside world. The installation location should not affect the operation of on-site equipment and normal activities of personnel. The installation height should be 2.5~5m indoors from the ground; outdoors should be 3.5-10m away from the ground, and no less than 3.5m. 2. The camera in the elevator car should be installed on the top of the elevator car, at the opposite corner of the elevator operator, and should be able to monitor the panoramic view of the elevator car. 3. The camera lens should avoid direct strong light to ensure that the target surface of the camera tube is not damaged. In the field of view of the lens, there must be no objects obstructing the surveillance target. 4. The camera lens should be aimed at the surveillance target from the direction of the light source, and should avoid backlight installation; when backlight installation is required, the contrast of the surveillance area should be reduced. 5. The camera should be installed near the surveillance target where it is not easily damaged by the outside world. The installation height should be 2.5-5m indoors from the ground; 3.5-10m outdoors, not less than 3.5m. 6. The camera in the elevator car should be installed on the top of the elevator at the diagonal corner of the elevator operator; the optical axis of the camera is at an angle of 45° with the two walls of the elevator, and a depression angle of 45° with the ceiling of the elevator. 7. The camera lens should be aimed at the surveillance target along the direction of the light source. 2. The method of debugging after installation is as follows: ①Turn on the automatic electronic shutter function of the camera; ②Use the controller to adjust the lens aperture to the maximum; ③Aim the camera at an object 30 meters away, and adjust the focus to infinity (mostly The lens faces the lens and rotates the front focus adjustment ring clockwise to the end); ④Use the controller to adjust the lens zoom to push the scene to the farthest, and adjust the lens rear focus to make the scene clearest; ⑤Use the controller to adjust the lens zoom to make the scene clear Pull to the nearest, fine-tune the lens focus to make the scene the clearest; ⑥Repeat 4-5 steps several times until the scene is always clear during the lens zooming process.
