How To Deal With Condensation In Security Camera Lenses

Condensation In Security Camera Lenses 1

Condensation on security cameras can lead to various issues, such as blurry images, foggy lenses, and recordings that only capture fog.

The fog-like substance inside your surveillance cameras is caused by a layer of condensation when water molecules in the air change from a gas back into a liquid. This differs from evaporation when a liquid turns into gas.

Most indoor security cameras won't present this problem on the camera lens. Yet, outdoor CCTV cameras can

Moisture can accumulate inside your lens when there are sudden changes in air temperature or humidity.

Left unaddressed, it can also cause corrosion and permanent failure of outdoor CCTV cameras. Therefore, it is vital to take effective solutions to prevent these problems.

Why Does An Outdoor Security Camera Get Condensation?

Condensation forms on the surface of the camera's warmest glass due to the difference in temperature between the air and the camera, as well as the level of humidity.

Condensation can form on your outdoor security cameras when they experience a sudden change in air temperature. This could be concerning, especially if you have expensive security cameras.

Security cameras often experience condensation due to inadequate sealing or lack of proper qualifications. In addition, outdoor cameras may falsely advertise water-resistance standards they do not meet.

CCTV cameras are not always completely sealed. Therefore, using inferior security cameras installed outdoors can increase your chances of experiencing camera condensation problems compared to using cameras from trusted security camera brands that are qualified.

Checking your security cameras regularly is essential, especially after severe weather conditions, such as heavy rains or snow storms. This is because the moisture build-up in the camera can be significant. 

Dew Point And Cold Temperature

Condensation occurs when the temperature of the outer surface of your lens drops below the dew point of the air inside.

When the moisture inside your camera lens reaches its limit, it condenses and turns into liquid form. This usually happens when the temperature hits the dew point. When it condenses, it causes fogginess and beading inside your lens.

How To Get Rid Of Foggy Images Or Prevent Condensation On Your CCTV Camera

Here are some solutions to preventing condensation:

Care With The Installation Process

When installing waterproof and weatherproof security cameras, it is essential to choose their installation spots carefully. Simply buying cameras with these features does not mean they can be placed anywhere. Take precautions and be mindful when selecting the best location for your outdoor cameras, especially if they are constantly exposed to direct sunlight or frigid weather.

Place the security cameras in secure locations. If you are worried about your residential or commercial security, we are experts in all kinds of surveillance cameras.

Clean The Lens With A Micro Fiber Cloth

Use a microfiber cloth to wipe the covers on the external focal point (not the focal points themselves) to prevent water spots. Another option to remove moisture from CCTV cameras is to use a hair dryer on a low heat setting and at a safe distance.

Waterproof Box

A surveillance camera housing can transform an affordable indoor-only camera into an ideal outdoor one. Moreover, you can use it outdoors immediately by safeguarding your IP camera with the appropriate security camera housing.

Get the appropriate camera housing if you want to use your indoor surveillance camera outside. 

Cheaper housing may work fine for cameras designed for the outside, but they might need to provide more protection for sensitive indoor cameras. Finding suitable waterproof housing to protect your camera from extreme elements is essential, especially in cold regions.


To reduce condensation, you can use desiccants to absorb moisture and dehumidify the area. However, you must remember to replace such desiccant materials periodically, as they will lose effectiveness over time.

Desiccants are substances used to absorb moisture from the air and help reduce condensation in security cameras. They work by adsorbing or chemically combining with the water molecules in the air, thereby eliminating humidity.

Various types of desiccants are available, such as a small packet of silica gel. Although inexpensive, it may not work efficiently since it needs to be replaced frequently.

Avoid Daily Temperature Swings

When warm and moist air comes into contact with the cold surfaces of a security camera, condensation may occur inside the camera, especially if there is a significant change in temperature within a day.

We suggest leaving your newly installed camera outdoors for around 72 hours if it has condensation. If the condensation does not go away within 72 hours, you may need to contact professional support teams.

Monitor The Weather For Condensation Issues

To ensure the optimal functioning of your security camera, monitoring the humidity levels and the working temperature is advisable. Avoid installing the camera in harsh weather conditions like wind, rain, and snow.

Our technicians can help you with these issues. However, it's best to have specialists handle the equipment selection and installation.

Anti-fog Spray For Security Cameras

Using anti-fogging sprays and cloths to prevent condensation on your surveillance cameras is not recommended. These products may contain high levels of potentially toxic PFAS "forever chemicals.

Tips For Both Indoors And Outdoors Surveillance Cameras

The following tips can help you with extra protection for your CCTV camera.

Select Security Cameras By High Weather Proof Ratings

You should choose from the top security camera brands when purchasing online or from local distributors. These brands have a good reputation for high-quality products and excellent customer service, including responsive support teams and extended warranty periods.

Weatherproof security cameras are assigned an environmental rating that indicates whether they are suitable for indoor or outdoor installation. The rating is derived from the camera's Ingress Protection (IP) rating.

Ingress Protection (IP) Rating

The term "ingress" refers to the act of entering. The three commonly used ratings for outdoor security cameras are IP66, IP67, and IP68.

A code called IP## is used to show the level of protection of security cameras against solids and water. The first digit of the code indicates the level of protection against solids, and the second digit indicates the level of protection against water. The higher the number in the code, the greater the protection.

IP65 to IP68

An IP65 rating can withstand most weather conditions but is not specifically designed to survive exposure to high-pressure water from a hose or similar source.

If the camera has an IP66 rating, it is resistant to dust and can withstand strong jets of water, such as those from a pressure washer that doesn't damage surfaces. It is a perfectly sealed camera.

If the camera has an IP67 rating, it is protected against dust and can be submerged in water up to 1 meter for 30 minutes.

If the camera is labeled as IP68, it indicates that it is completely sealed against dust and is capable of withstanding extended periods of water immersion under pressure, even at greater depths.

Clean the Security Camera

It is crucial to clean security cameras periodically; for wire-free or wireless cameras, the first step is to remove the battery.

Remember to disconnect the power adapter from the electrical outlet if you are cleaning a wired CCTV camera. Doing so will help avoid any harm to the camera.

To clean the camera properly, begin by unscrewing it from its mount. This will allow you to access the camera quickly.

To clean the camera, use a clean and dry cloth to wipe down the lens and the camera's body.

A compressed air can is recommended to clear any dust or dirt accumulated on the camera.

Attach it back onto its mount, and fasten it tightly to prevent it from becoming loose while in use.

To prevent future condensation issues with the security cameras, you may apply the waterproof gel on all the seals and gaskets after cleaning.

We recommend contacting the support team before wiping off condensation from the CCTV camera to avoid invalidating the security camera warranty.
