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…
Divided by imaging color (1) Color camera: It is suitable for distinguishing the details of the scenery, such as distinguishing the color of clothes or scenery. The amount of information increases due to the color, and the amount of information is generally considered to be 10 times that of a black-and-white camera. (2) Black-and-white camera:…
