How To Stop Your Doorbell Cameras From Freezing: 5 Tricks To Manage Fog And Frost

We know how frustrating security camera freezing is during the colder months.

Doorbell cameras are especially susceptible to fog and frost, which impacts viewing capabilities. 

While fog and frost on the lens is common in cold climates, there are solutions to the problem. Discover our essential tips to stop your doorbell camera freezing.

Why Does My Doorbell Camera Keep Freezing?

Doorbell cameras freeze because the air has a high moisture content, while the device has a low surface temperature. 

When the air temperature reaches the dew point, water vapor condenses to become a water droplet. 

If the temperature drops below 0 Celsius or 32 Fahrenheit, dew solidifies into ice crystals.

5 Ways to Stop Doorbells from Frosting

It’s all well and good knowing why doorbell cameras are sometimes subject to frost and fog, but how do you deal with it? Learn how to prevent frozen security cameras with these five clever tricks.

1. Ensure correct placement

Ensuring correct doorbell camera placement is the best way to prevent it from frosting.

Unfortunately, it’s not often as straightforward as positioning other smart home technologies. After all, security cameras often need to be outdoors.

Installing the doorbell camera outside shaded areas helps reduce the chance of dew crystallizing.

Strong morning sunshine helps evaporate overnight condensation and prevent frost formation. 

Choosing a doorbell camera location away from cooling and heating appliances, such as HVAC technologies and dryer vents, is preferrable.

Position the doorbell camera away from moisture-rich fixtures and features, such as landscaping systems, pooled water, drains and gutters.

2. Bring the doorbell camera indoors to dry 

Check the doorbell camera’s internal fogging to determine its severity. It’ll be fine if there’s only a speck of moisture inside—gently dry it out using a towel or tissue.

Water and electronics aren’t buddies. Prolonged contact with moisture causes irreparable damage.

You can get the same effect by placing the device in dry white rice. 

3. Water ingress protection

Doorbell cameras are outdoor devices constantly exposed to the elements, so they need adequate ingress protection.

All outdoor security cameras should at least be IP65 rated to protect it from dust and water. But this doesn’t mean it can be completely submerged in water.

If concerned your doorbell camera isn’t sufficiently waterproof, try applying Rain-X or similar water-repellent products. These solutions create a waterproof coating on the casing of the camera, making the surface too slippery for water molecules to stay on.

‘I had this issue with my doorbell. Condensation would get on the lens and make it useless. I emailed support, they told me to spray it with RainX.’

Wrapping a silicone sleeve around the doorbell camera is another great way to increase weatherproofing.

Much like wearing a waterproof jacket in the winter, sleeves prevent water from seeping into the device and stabilize the temperature, reducing the risk of doorbell camera fogging and frosting.

4. Apply anti-fog coating

There are two types of anti-fog coating: hydrophobic and hydrophilic. What’s the difference?

ActionRepels or pushes water molecules awayAttracts or pulls water molecules closer
Water droplet-surface angle requirementGreater than 90 degrees90 degrees or less
Expected effectsPrevents water molecules from sticking to the surfacePrevents water molecules from breaking into tinier water globules, allowing for effortless wiping
Recommended applicationsSuitable for preventing fogging on glass and non-plastic surfacesIdeal for preventing fogging on plastic surfaces

Be aware that this trick might void your doorbell camera’s warranty.

Install a heat trace tape

“You can get not very expensive kits containing a length of heated tape and a thermostat, known as “trace heating.” Wrapping some of that round the camera and lens is one way to do it – even better is it’s inside an enclosure. It uses power but not too much. Mine takes 12W per meter when it’s on.”

How do I keep frost off my security camera?

Covering the doorbell with a sleeve also prevents condensation on its surface. Drying the doorbell with a microfiber cloth as frequently as possible will help stop it from frosting.

How to stop your doorbell cameras from freezing at night?

Covering the doorbell camera with a silicone sleeve or heat trace tape prevents condensation on its surface. Applying anti-fog coating products is also useful, but be aware of voiding any product warranties before doing so.

How do you keep a doorbell warm in the winter?

Ring also advises monitoring the battery temperature and charge level. It should be 100% charged with a temperature higher than 36 degrees Fahrenheit.

Do doorbell cameras work in cold weather?

Doorbell cameras work in cold weather so long as the temperature isn’t below the device’s minimum operating threshold.

What temperature can a doorbell withstand?


You don’t need to become a hostage to doorbell camera fogging and frosting. Positioning the device in the ideal location helps significantly, while applying an anti-fog coating, protecting it in a weatherproof enclosure, or using a heating tape aids in dealing with consistent fog or frost formation. 

This allows you to continue using your smart home device, optimizing its many benefits.
