How Does a Dash Cam Work?

A dash cam is handy in many ways. Out of all the accessories bought for vehicles, the dash cam is the most frequently used. You use it to record videos on the inside and outside of your vehicle.

Now the question is, how does a dash cam work? Starting from installing to turning it on or off, we’ll discuss it all right now.

Steps to Using a Dash Cam

We all know what a dash cam is. It’s a small technological device made to record videos while mounted on the dashboard or windshield of a vehicle. There are different types of dash cams, like the rearview mirror dash cam, dual camera dash cam, GoPro, and others.

After you’ve chosen your suitable dashboard camera to use for your vehicle, let’s jump to the stage of finally using it:

Step 1: Installation

The first step is installing the dash cam that you bought. Most dash cams are easy to install. Mounting the device inside your vehicle depends on the area. If you want it on the dashboard when using any kind of adhesive tape will do.

And if you want it on your windshield for a higher view, then use suction cup holders and fasten the camera on.

Step 2: Power Supply

The dash cam is usually connected to the car’s battery. You just have to wire the dash camera to this power supply.

There are other routes to connecting it to a power supply. One is to wire it to the cigarette lighter outlet for power. Another is to connect it by USB cable found in some modern cars.

If you want a more complicated but attractive way to power, then you can try wiring through the car’s lining. If you can’t do it yourself, then try calling a mechanic to handle the cables. You can do the same thing for a dash cam for trucker as well.

Step 3: Turning It on

Once your dash cam has a connection to a source of power, you can try turning it on. Some dash cams turn on automatically when you start your car. It begins recording right at that moment and stops recording when your car isn’t running anymore.

But there’s also a feature called “parking mode”. This is the opposite setting from the default one. Here the camera starts recording when your car is idle or not moving. It’s for recording footage when your vehicle is parked.

Step 4: Loop Recording

Loop or continuous recording is something that’s programmed into dash cams. It will keep recording even when the memory is full. When this happens, the footage at the beginning will get erased, and the space created will be made for new footage. This is automatic and can’t be undone.

But the advantage here is that old footage that you won’t need will get replaced. So, you won’t need to go through the entire memory card to erase it every time to use it the next time. It will manage that task on its own.

Step 5: Footage Reviewing

Since the footage is recorded automatically and continuously into the memory card of the dash cam, all you need to do is take that SD card out. Just insert the card into an adapter and connect it to your computer and view it with any video player you have on your computer.

Also, note down that most dash cam footage videos come in the “.avi” format.

Step 6: Dual Cameras

Dual cameras are also known as 360-degree cameras. These have 2 cameras on the opposite side facing in two different directions. The dual cameras record both the inside and outside of the vehicle at the same time. These are the best dash cam for the front and rear.

This wouldn’t be the best motorcycle dash cam since there’s no interior to record on a motorcycle. But if you need a dash cam to record surrounding scenery on the road for media purposes, then you can keep the 360 lenses side to side instead of front and rear.

Step 7: GPS Logging and Speed Detecting

There are some complex and expensive dash cams available that do more than just recording video. These complex dashboard cameras can also track GPS and speed. They’re usually used by people of the law rather than regular citizens.

By using the GPS tracking system, the police or investigators can find missing people, whether they’re adults or children. It’s even used by taxi companies to track drivers who drive off with the company vehicles. This way, they can file reports and insurance claims.

The speed detector is for police who are handling highway speed limit laws and making sure there aren’t any drivers driving over the speed limit so that they can stop them and give them speeding tickets or arrest them.

Step 8: Night Vision Mode

You’ll find night vision settings on dash cams as well. Dash cams with a WDR or Wide Dynamic Range feature give a low light setting on the camera. You can adjust the exposure yourself so that it can pick up footage in the dark.

Also, you can use LED lights on dash cams to make night vision easier, even though it gives poor video quality.

Final Words

The dashboard camera is slowly becoming legal everywhere, mostly because it’s helpful to save innocent victims caught in trouble. The dash cam helps with location and footage evidence issues.

Different dashcams have different features, so depending on why you’re using the dashcam, you should set it that way. For example, if you’re a taxi driver, then keep the audio recording setting off to not record any private conversations of customers.

Hopefully, you can learn how a dash cam works, starting from how to install it, to how to store the data.
