The camera or housing lens as well as the front LCD may fog up. This typically happens when the camera is warmer than the cool or humid environment it is in, and it is especially prevalent when the camera is used underwater. In motion cameras, the temperature difference between the camera and the surrounding environment can cause condensation on the lens and LCD, which is a common issue during underwater photography or in humid conditions.

How can this issue be resolved?

The fogging dissipates when the temperature of the camera and the environment becomes equalized, much like how the fog on your car's windshield disappears once the heater warms it up. It should be noted that fogging does not cause any damage to the camera. In motion cameras, this process of temperature equalization is crucial for maintaining clear images.

If you are using the camera with its housing in an environment where the lens is fogging, you can utilize anti - fog inserts specifically designed to mitigate this problem. These anti - fog inserts are effective in preventing the housing lens of your camera from fogging, even in cold or humid environments. For motion cameras, anti - fog inserts are an important accessory, especially for those used in extreme environmental conditions.

Here are some additional steps that can be taken to prevent or minimize fogging:

(1) If you are using the camera in conditions where waterproofing is not required or where high wind noise is not a concern, then you should open the back door of the housing. Opening the back door of the housing will ensure that the temperature inside and outside the housing is equalized. In motion cameras, this step can be useful when shooting in relatively dry environments where the risk of water ingress is minimal.

(2) Turn off any unnecessary settings (such as Wi - Fi, Voice control, etc.), as this helps the camera operate at a lower temperature. In motion cameras, many additional features can generate heat during operation, and turning them off can reduce the overall heat production, which in turn can help prevent fogging.

(3) Keep the camera as cool as possible if it is about to be exposed to a colder environment. For example, if you are going diving, keep the camera in the dive boat's bucket of freshwater for rinsing gear until it is time to use it. If you are at the beach, keep the camera in the shade rather than in the sun. In motion cameras, maintaining a lower temperature can reduce the likelihood of fogging when moving from one temperature environment to another.

(4) Ensure that when you open the battery door, your hands are dry and the camera is dry as well. In motion cameras, moisture can cause various problems, including short - circuits and further fogging issues.
