Can the front cover of the infrared hemisphere camera be removed?
The infrared hemisphere camera lays cables with appropriate wire diameters according to the distance from the front camera to the monitoring center; The line is too long and the cable used is too thin, and the signal attenuation of the line is too large to meet the needs of image transmission, resulting in poor image quality watched by the monitoring center; If the camera adopts DC 12V centralized power supply.
Heat dissipation of infrared hemispherical camera;
Because the infrared lamp generates a large amount of heat, during the whole working period (12 hours), there will be heat concentration in the front of the infrared camera, that is, the temperature in the front of the cavity is too high, and if it can't dissipate heat evenly, it will affect the normal work of other components such as the camera.
Because the radiation power of infrared LED is directly proportional to the current, many non-standard manufacturers increase the current to improve the irradiation effect. However, the greater the current, the higher the temperature. Although the irradiation effect is improved, the machine itself will be greatly damaged due to the overheating of LED. Among them, the CCD behind the LED board is the most direct victim.
