Fog and frost, at OHWOAI Surveillance, we understand the importance of maintaining clear and reliable surveillance footage. The occurrence of fog and frost can affect security camera visibility and reduce the effectiveness of surveillance. In this article, we will explore internal and external fog countermeasure methods while incorporating related keywords.

Anti-fog inside: Fog or frost is formed when water vapor becomes saturated and condenses due to cold temperature. Especially for indoor infrared cameras, fog or frost may adhere to the viewing window of the protective cover, obstructing the camera's view and negatively affecting the monitoring results.

There are various approaches to address this issue. These include implementing defrost circuits, installing vents, injecting nitrogen gas, installing fans, utilizing desiccants, etc. Each method will yield different results, and some will be more effective than others. However, from a basic security perspective, strict control over component cleanliness is key. Measures such as thorough cleaning of components, ensuring removal of residual flux on PCB boards, and using high-quality silicone for light-shielding covers are highly recommended.

Anti-External Fog: In high humidity environments, surveillance cameras can face visibility issues due to dirt on the viewing window of the protective cover, which obstructs the camera's view.

To address this issue, consider the following solutions:

Check for internal condensation.

Make sure the lens cover is securely attached to the camera glass.

Check if your camera has a lens cover.

Check whether there is any condensation on the CCD inside the camera.

Check if the electronic shutter is enabled and disable it if necessary.

Make sure the infrared light board is parallel to the lens and maintains a consistent angle between them.

Taking these measures will solve the visibility problem caused by external fog.

Make sure the lens cover is slightly higher or exactly the same height as the lens itself (usually lens covers are meant to be 3-4 millimeters higher).

By following these steps, you can enhance your circuit cerrado de camaras (closed circuit camera) or store surveillance camera system by combining OHWOAI Surveillance's advanced 8 channel IP camera system, 4K security cameras, PoE (Power over Ethernet) capability and 24/7 recording.
