How to Clean Dome Security Cameras

Sharing is caring!

If you’ve ever been in the market for a security camera, you may be considering dome security cameras as a good option. Dome security cameras are unique in that their shape is more rounded or dome-like than typical security cameras. They’re great for when preventing tampering and vandalism is a must. While dome security cameras offer several benefits, they can require a bit more maintenance than other security cameras. In this article, we’ll teach you how to clean dome security cameras, including the dome, body, and housing.

How to Clean Dome Security Cameras

You may think that dome security cameras are impervious to the elements since the camera portion is protected by a transparent dome cover. However, dirt and dust can actually get trapped within the camera’s casing and build up over time, which can impact the camera’s performance.

Here are some tips for cleaning your dome security camera:

1. Begin by turning off your camera. This will prevent any accidental damage that may occur due to the camera being switched on while you are cleaning it.

2. Use a microfiber cloth to gently wipe away dust or dirt from the camera lens and housing. A soft, lint-free cloth is the best choice for cleaning your dome security camera because it will not scratch or damage the camera surface.

3. You may need to use a slightly dampened microfiber cloth to remove any heavy build-up of dirt or grime. Be sure to thoroughly dry your dome security camera once you’ve finished cleaning it since the remaining moisture could cause further damage.

4. Open the dome cover to access the interior and clean light dirt or dust with a micro-fiber cloth. Avoid using a wet cloth to clean the camera, as this may damage the internal parts.

5. If your camera dome is covered in dirt, grease, or fingerprints, you can clean it with a simple solution of warm water and dish soap. Gently wipe the surface with a microfiber cloth until it’s clean. Avoid using paper towels as they may scratch the dome.

6. If there is more stubborn debris or grime stuck inside or outside the camera, you may need to use a small brush or an air compressor to remove it. Be sure to let the camera dry completely before you put it back in use.

7. Check for any insect eggs or spider webs inside your dome security camera’s enclosure before putting it back together.

8. Additionally, it’s important to regularly check your dome security camera’s power supply and wiring for damage. If you notice any signs of wear or damage to the cables, you should contact a professional for a repair or replacement.

Cleaning Products to Use

Many dome cameras are made from plastic or other synthetic materials that may be affected by harsh cleaners.

We recommend:

– Mild soap and water or a specially formulated lens cleaner to remove dirt and dust from the camera’s surface.

– Compressed air can be used to dislodge stubborn dirt that doesn’t come off with the other cleaning methods.

– A soft microfiber cloth is an effective tool for cleaning the dome camera’s surface and lens.

– A lint-free cloth is a good choice for cleaning your dome security camera if you are worried about scratches or damage to the surface.

Cleaning Products to Avoid

The following products can easily damage the dome, thereby reducing IR clarity and significantly distorting the image.

We strongly discourage:

– Anti-Bacterial or harsh (extra-strength) detergents that can cause damage to the dome’s surface.

– Rough materials or scrubs (such as steel wool or Brillo pads) that will leave behind harmful scratches or abrasions.

– Chemicals or other harsh cleaners, such as bleach or ammonia, that cause discoloration and permanent damage to the dome camera’s surface.

– Acids, solvents, or abrasive cleaners that will eat into the plastic or synthetic materials of your dome camera, causing severe damage.

– Paper towels, newspaper, or other rough materials are not suitable for cleaning dome cameras, as they can easily cause scratches or other damage.

Why Clean Dome Security Cameras?

Your dome security cameras can tend to get dirty more quickly than other types of security cameras. Dome security cameras are often exposed to the elements, which can make the susceptible to dirt, dust, and cobwebs. If not cleaned regularly, dirt and dust can cause your camera to malfunction.

When dirt accumulates on the camera dome, the camera’s autofocus function can become focused on the dirt or dust-covered dome, blurring the image. A light build-up of dirt or dust can cause the infrared LEDs around the camera’s lens to reflect back into the camera sensor. You should review the images regularly from the camera to guarantee sufficient image clarity.

Regular cleaning can also help increase the image quality of your footage. When a camera gets dirty, the lens gets foggy and the image becomes distorted. Cleaning your camera regularly will help maintain optimal image quality and ensure that your video footage is clear and easy to see.


If you want to ensure that your dome security camera is clean and free from debris, follow these simple tips. Whether you need to clean the lens, housing, or interior of your camera, a few simple tools and cleaning products are all you need.

For light dust or dirt, a microfiber cloth will do the trick; for more stubborn build-up, you may need a dampened microfiber cloth or compressed air.

Avoid using harsh chemicals, such as bleach or ammonia, which can cause permanent damage to your dome security camera and reduce image clarity. And remember to regularly check your camera’s power supply and wiring for signs of wear or damage, so that you can address any issues as soon as they arise.

With these tips, you can keep your dome security camera in top condition and ensure that it continues providing high-quality images and videos.

How often should I clean my dome security camera?

You should clean your dome security camera regularly, at least once a month or as needed. Depending on environmental factors such as humidity, dust, and temperature, you may need to clean your camera more frequently.

Why is my dome security camera foggy?

If your dome security camera has a foggy or distorted image, it may be due to dirt and dust accumulating on the lens or on the outside of the dome cover. This can disrupt the autofocus function, the IR night vision, and image clarity, resulting in a foggy image on the video monitor. To prevent this from happening, you should clean your camera regularly to remove any dirt or dust buildup.

How do you know if your security camera is dirty?

If you notice that your security camera is not providing clear images or that the image appears distorted, it may be due to dirt and dust on either the lens or the camera dome. Additionally, you may also see a hint of discoloration on the camera surface, which can be an indicator of more serious damage. To clean your dome security camera regularly and ensure optimal image quality, follow the simple tips in this article.
