What are the advantages of high-definition outdoor cameras With people’s continuous pursuit of image clarity, high-definition surveillance has gradually become the development trend of the industry. For high-definition surveillance cameras, the clarity of the image has undoubtedly become an advantage, because the clearer the image, the more obvious the detail performance, and the recognition effect…
1. The debugging of the infrared light should be carried out at night. Adjust the position of the infrared lamp illumination at night through the display. 2. The cable from the surveillance camera should have a margin of about 1m so as not to affect the rotation of the surveillance camera. 3. Infrared integrated camera,…
What are the precautions for installing outdoor cameras? 1. Under the premise of the target range, the installation height: the installation height of the indoor camera is 2.5～4m, and the outdoor is 3.5～10m; the elevator car is installed on the top of the elevator car at a diagonal angle to the elevator manipulator. , And…
related information 1. Surveillance camera lens Focal length: The focal length of a surveillance camera refers to the distance between the lens and the photosensitive element. The magnification of the lens is approximately equal to the ratio of the focal length to the object distance. In other words, as the focal length of the surveillance…
CCTV camera related terms explanation (1) Resolution: The resolution in the use of a surveillance camera refers to the number of dots displayed in the horizontal and vertical directions of the screen. The higher the resolution of the surveillance camera, the clearer the captured image. (2) Definition: The sharpness of the surveillance camera is represented…
common malfunctions 1. No image First check whether the polarity of the external power supply is correct and whether the output voltage meets the requirements (power supply error: DC12V±10%, AC24V±5% ), secondly, check whether the video connection is in good contact; if you use a manual iris lens, you need to check whether the iris…
Common malfunctions 1. Infrared hemisphere series machines have poor image illuminance, whitishness or bright white aperture at night. This phenomenon is caused by improper assembly of the machine. During assembly, the photosensitive device (photoresistor) is too far away from the hemisphere, which will cause the infrared light to start incompletely. Causes the machine to have…
The development of the integrated camera is to provide consumers with a product that is easy to use, easy to install, and fully functional. Debugging method 1. Turn on the camera’s automatic electronic shutter function 2. Use the controller to adjust the lens aperture to the maximum 3. Aim the camera at an object 30…
Installation process 1. The wire used for surveillance cameras should have a rated voltage greater than the working voltage of the circuit; the insulation of the wire should conform to the installation method of the circuit and the environmental conditions for laying. The cross-sectional area of the wire should be able to meet the requirements…
Divided by camera sensitivity (1) Ordinary type: the illumination required for normal work is 1~3 LUX (lux) (2) Moonlight type: the illumination required for normal work is about 0.1 LUX (3) Starlight type: the illumination required for normal work is below 0.01 LUX (4) Infrared illumination type: In principle, it can be zero illuminance and…
