Spread the love

Reverse cameras are designed to offer drivers an extra option when reversing their vehicle. These cameras are also known as backup cameras. They are attached to the exterior of the car and provide an image to video screens inside the car. This is a great safety measure for drivers. But there are instances where moisture can get in between the camera and display screen.

The moisture will eventually dry out on its own if left alone, or it can be removed by wiping it with a towel or cloth. If the camera lens is still wet after cleaning the screen, then the moisture is likely found inside the camera. In this case, you need to remove that moisture as soon as possible. In this blog post, we will show you how to remove moisture from the reverse camera. So, let’s get it.

What is Moisture and How Does It Affect the Reverse Camera?

Moisetured cameraAccording to Wikipedia, moisture is the presence of a liquid, especially water, often in trace amounts. Small amounts of water may be found, for example, in the air (humidity), in foods, and in some commercial products.

Moisture also refers to the amount of water vapor present in the air. The moisture can also be on the lens and it makes the camera’s lens foggy. Let’s take a look at this picture:
You can see the foggy camera or moisture on the lens. This is the moisture that is slowing down the operation of the camera.  Also, it makes the camera’s viewfinder impossible to see anything in front of the camera.

Moisture usually gets on the camera by dripping from the weather conditions or the water that is on the ground. Similarly, reverse cameras easily get moisture from rain, fog, snow, and dew as they are usually installed outside the car.

Now the question is, what are the best ways to remove that moisture and how to protect the camera from it? You will get the answer in the remaining parts of this article.

How to Remove Moisture from Reverse Camera?

Your reverse camera can be foggy and covered with moisture because it’s constantly exposed to the weather. It can happen for many reasons: maybe you left your car in the rain or you had a snowstorm and your car slipped on the wet pavement and hit your camera.

It doesn’t matter how you got the moisture onto your camera, the first thing is to remove it. Anyway, if your camera’s lens gets moisture then you should remove it as soon as possible.

Fortunately, you don’t need much in order to dry out your camera, you just need air. You can do this by following a few steps. So, let’s get started

Check the Lens for External Faults

If the lens is covered in moisture and dust, you should first check if the lens is the cause of the problem or it is just an accident. If the lens seems to be too wet, you should immediately take it off and leave it dry. Do not wait, because the longer you leave it, the stronger the moisture becomes.

Wipe the glass surface of the lens with a dry and soft cloth. If the lens is dusty and covered, then you must first remove the dust particles. To do this, you need to slightly loosen the dust particles by spraying glass cleaner. Then carefully remove them using a soft brush or cotton swabs.

To remove the remaining dust particles, you should let the camera stay in a dry and ventilated environment. Finally, spray an anti-moisture layer, such as Rain-X to keep it safe from getting dirty again.

Check for Interior Condensation

The reverse camera lens has a large opening so that it can be cleaned in a matter of seconds. If you find condensation on the inside of the camera lens, then you should clean it immediately and dry it off completely.

Here is how to clean the reverse camera’s lens:

Method 1

At first, remove the camera from the car. Be careful while doing this, don’t break any part. Now, clean the whole camera with a soft and dry cloth. After that, you need to submerge the camera into some dry substance that encourages dryness and sucks up moisture.

You may get several such substances but uncooked rice will be the best option. It works magically in sucking moisture. So, submerge the camera into uncooked rice and wait until it’s dry completely.

Method 2

If you’re in a hurry or shortage of time you can do the same thing by using a blow dryer or hairdryer. In this method you need to do this carefully otherwise the hot air can damage the plastic parts of the camera.

Now, using a blow dryer, heat the camera for 2-3 minutes at a medium setting. This will help to dry the lens and remove any additional moisture.

Check the Cables and Electric Connections

Your camera can get moisture due to faulty electric connections. Sometimes it may be happened due to overvoltage or any other power issues like a blown fuse. So, you need to be sure whether the electric connections are ok or not.

Here is how to check the electric connections:

Turn on the vehicle and switch on the reverse camera display. If the display doesn’t turn on then we can say that the display is faulty. In this case, the display needs further treatment. But if the display turns on and loads but the camera doesn’t show any image then the display is ok and the problem is supposed to be in the power connections or camera itself.

In this case, at first check the cable connections of the display and the camera. To be sure about the connections diagram, you may read the manual. Don’t forget to check your car’s fuse box if there is any blown fuse. If any, replace it with a new one.

Now, if you find everything ok including electric connections, camera cables, fuse, and display then the camera is faulty. So, you need to take further steps.

Replace the Faulty Camera

If none of the above solutions work then you need to repair the camera by experts or replace it with a new one. You can always buy backup cameras from local or online markets. Don’t forget to claim the warranty if your camera is under warranty period.
