Why Does Infrared Camera Fog? Will PTZ Installation Environment Affect This Fault?

Why does fog often appear on infrared surveillance cameras? Can improper installation of Pan-Tilt or PTZ aggravate the fogging problem? What practical solutions can thoroughly solve camera fogging?

Fogging is a common failure of infrared cameras, which makes the monitoring picture blurry. Fog mainly appears on the inner lens, internal glass and outer protective cover. Do you know the root cause of this phenomenon? It is closely related to ambient temperature and air humidity. When the infrared function is turned on at night, the internal temperature of the camera rises, and water vapor condenses into fog on the glass surface.

Will the matching Pan Tilt Zoom and Pan-Tilt affect the sealing performance of the whole equipment? If the camera is installed on outdoor PTZ, the device needs to work in high humidity, rainy and cold environments. Poor waterproof and sealing design will let external water vapor penetrate into the shell, causing internal fogging.

How to deal with internal fogging of infrared cameras? We can add defrosting circuits, ventilation holes, fans or desiccants. Fundamentally, we need to use high-quality production materials, control the humidity of production environment, and strictly optimize waterproof technology with rubber sleeves and waterproof glue.

What if fog covers the outer glass cover? This kind of external fog has nothing to do with the camera itself or the installed Pan-Tilt. We can install wipers or water-repellent coatings on the protective cover to keep the glass clear. Whether equipped with common brackets or professional Pan Tilt Zoom, good daily maintenance can effectively reduce fogging failures.
