Physical Adsorption Desiccant
When the security monitoring camera is running, the internal ciruit heats up and generates high temperature. If the air humidity is high, when the temperature drops, the lens of the monitoring camera will produce water drops, which will affect the imaging affect of the monitoring camera and its life. therefore, it is necessary to put a desiccant in the camera housing to absorb the water vapor in time and reduce the air hunmidity to prevent fogging and water droplets.
