How to Clean Your Security Camera and Lens

The benefits of keeping your CCTV cameras clean means that when you need them the most, they’ll be there for you.

We can’t think of a single piece of equipment that doesn’t require maintenance. That includes the commercial security system at your business. Typically, these units are fairly maintenance free. But there is one thing you should do periodically: Keep your CCTV cameras clean. This blog will answer some important questions surrounding how to clean your surveillance cameras.

Your cameras can fall victim to dust, dirt, cobwebs, and weather. Cleaning your security camera lens will ensure years of foolproof service. Clearing the housing from any debris while carefully cleaning the surveillance camera lens will ensure a crystal-clear picture of your property at all times.

If your camera is outside, environmental conditions can smudge up the lens and obscure your vision. Dust is still probably the top lens smudger on the outside of your business. However, mud, leaves, bugs, and even rain drops can hamper observation. This could affect not only the picture but the analytics running behind your smart camera lens. While a few stains may not seem like a big deal, this creates a cumulative effect until vision is obscured. 

If you’ve ever seen a bird nesting on a CCTV camera, you understand the conditions that could affect this equipment. Rodents and birds can find cable insulation a good nesting material. Spiders frequently build webs right over the housing of the camera. We’ve even seen bees and wasps building nests off the camera housing on a pole or the side of a building. In the winter, the warmth of a camera can be an attractant.

Making matters worse, today’s smart cameras are particularly vulnerable to these encroachments. For example, a zoom lens could end up focusing on the spiderweb instead of the external shot. Light from the ring of the camera’s infrared illuminators can reflect visual information back to the software improperly if there’s an accumulation of dirt on the camera housing. These cleaning tips also apply indoors, although the four walls do provide a measure of protection against critters, rain, and other elemental conditions.

The benefits of keeping your CCTV cameras clean means that when you need them the most, they’ll be there for you. You are placing a lot of faith in these tools. A good security system pays for itself every day. However, you as the owner must take steps to clean the surveillance camera lens on every unit regularly to keep them in tip-top shape. 

How Often Should I Clean My Surveillance Cameras?

How Often Should I Clean My Surveillance Cameras

You should clean your security camera lens on each unit at least every three or four months. Clean your CCTV cameras more often if they’re exposed to serious weather and you notice problems with the visuals you’re capturing. 

Another tip to consider is to look at the conditions surrounding the CCTV camera as you’re cleaning it. Specifically, are there external conditions that could block your visual feed? Does shrubbery need to be cut back from summer growth? Does the camera angle need to be changed slightly? Look at the images produced by each camera to determine: a) If it’s clean; and b) If it’s still producing the right visual you need.

Cleaning a dome camera lens is different from cleaning a box camera. Both require careful dusting with a soft brush, an air can, and a microfiber cloth. Here’s how to clean the security camera lens on both of these types of installations.

How To Clean a Dome CCTV Camera Lens

If your cameras are hard-wired, start by shutting off the breaker to the cameras, just to be safe. If you have a traditional dome surveillance camera, you must carefully clean inside and out with a dry soft brush or a can of compressed air. A microfiber cloth also works well and doesn’t scratch the lens.

If there’s dirt on the dome camera, it can cause the autofocus to concentrate on the dome itself and not the video beyond it. You’ll see this as an out-of-focus image. If there’s a lot of dirt or debris on the outside of the dome, gently use the soft brush to whisk it away. You can use compressed air as long as you’re careful to put the spray nozzle too close to the camera. This could actually push the debris into the camera and scratch the lens. 

Gently remove or open the dome housing and use a microfiber cloth to carefully remove any dust or dirt. Don’t use paper towels. Just like they’ll scratch the lenses of your glasses, they can also damage the camera’s vision.

Inspect for spider webs, eggs, or any rodent damage. Close the housing and you’re good to go.

To keep these CCTV cameras clean, you should again, rely on your air can, soft brush, and microfiber cloth to brush off the equipment. If the camera is muddy or greasy, you can use a little warm soapy water on the cloth itself to wipe it down. 

Again, safety first. Shut down the breaker to your hard-wired cameras as a first step in the cleaning process. Many outdoor box cameras also have a fan or even a heater, depending on where they are located. Some units can open, so inspect the interior for insect eggs and bugs during that process. If you spot dangerous insects such as bees or wasps, consider calling an exterminator to reduce your injury risk. While you’re cleaning the security camera lens, take a look at the wiring. Is the insulation intact? Are the wires exposed? Is anything fraying or cracked? 

If the cameras are wireless IP security cameras, you can skip this step.
