Avoiding condensation in your outdoor CCTV cameras can be so easy, outdoor cameras are made to be waterproof, the condensation you might likely get in the front-end of your lens is never caused by water getting into the camera.

Condensation in outdoor cameras are caused by changes in the weather especially during the spring and fall, where the sun may cease to fall on outdoor cameras after they have been exposed to moisture in which we cannot prevent.

condensation in outdoor CCTV camerasCondensation simply occurs because air can only hold a certain quantity of moisture. Warm air can hold more moisture than cold air, when warm air meets a cold object such as outdoor CCTV camera glass surface, the air immediately cools down and releases some of the moisture it is holding, which causes the CCTV camera to fogs up on the inside.

Condensation on the surface of the CCTV camera lens can cause the camera to be blurry which is not good enough for video surveillance security. Condensation in another manner stays on the surface of the camera lens which distorts image sensor from picking a clear vision.

Silica gel is relatively easy to find, you might get it electronics or fashion packages.

Silica gel was in existence as early as 1640, it was used in World War I for the adsorption of vapors and gases in gas mask canisters. The man-made itinerary for producing silica gel was patented by chemistry professor Walter A. Patrick at John Hopkins University in 1919.

Silica gel was very essential during World War II in the effort for keeping penicillin dry, protecting military equipment from moisture damage. Silica gel is a desiccant, it adsorbs and holds water vapor. Silica gel is nearly harmless.
