How to Fix Condensation on Camera Lenses Leave a comment

Condensation has plagued lenses of all varieties since their invention. This becomes a greater concern when the camera that’s view is being obstructed is guarding your property and loved ones. It is a natural occurrence, however it can be prevented and minimized with the proper precautions and maintenance. Using the correct types of cameras and housings is half the battle, the rest is a few simple techniques I’ll talk about here.

How Condensation Forms:

Not a Perfect Seal

A primary cause of condensation in security cameras is that they are not properly sealed. Often times with cheaper cameras, they do not offer the water-resistance rating they claim. These should be avoided as most times, they will quickly fail and you will spend more money replacing them with the proper equipment.

Large Daily Temperature Fluctuations

Especially in Texas, it is not uncommon for there to be rain, shine and rain again all in the same 24hr period. This creates optimal conditions for condensation to form. Depending on the area you reside, you may be more or less susceptible to condensation. If you do live in an area with a greater risk of condensation, you may want to consider some specialty housings for your cameras.

Severe Weather

Severe weather can also cause an overt amount of moisture to build up in a camera. You should check all your cameras after a large storm to ensure they are functioning properly. Most specialty housings can aid with this, as well as purchasing a camera from a reputable manufacturer. Unfortunately, machines have issues and require maintenance so it is still important to check your system, as it is there to protect your family and property.

Indoor Cameras Used Outdoors

Another factor that causes condensation is when indoor cameras are used outdoors. This occurs due to either ignorance or budget restrictions. Indoor only cameras tend to be cheaper compared to outdoor ones because the housings are less durable and easier to produce. Indoor cameras are perfectly reliable and durable when used how they were designed to be, however I wouldn’t recommend skimping on these when you know they’re going to be installed outdoors, it will save you money in the long run.

How to Fix Condensation Issues:

Wipe Off the Lens

The simplest solution is to merely wipe off the cameras lens, although, this will need to be repeated on every occurrence and can become very time consuming. Unfortunately, it is a necessary step to remove already accumulated condensation from your lens.   

Remove Dome Covers and Wipe Off

You should also remember to remove the dome covers on these styled cameras and wipe away any moisture that has accumulated there as well.

Anti-Fog Spray

After you have wiped down your lenses and covers, you should apply and anti-fog spray to help prevent condensation from occurring later on. This is a good time to apply the spray as you are already performing similar maintenance to clean the lenses.

Weatherproof Housings/Mounts

Weatherproof housing and mounts are one of the best solutions to condensation issues. They are designed for use in harsher environments and surround the camera with another layer of protection from the elements.


Silica Gel and other desiccants can also be stored in the unit to help draw in accumulated moisture, dehumidifying the area. These are a great and cost-effective way to help with condensation problems. The downside to these are that they must be replaced every so often or they stop functioning.

Heaters and Blowers

Heaters and blowers can also be installed to help internally regulate the temperature of the camera. This keeps a more constant temperature inside the unit allowing for decreased risk of condensation. Some models are tricky to install and should be done so by professionals, however some come built in to weatherproof housings for easy installation.
