How Do Dashcams Work?

Dashcam cameras are designed to be placed at either the front or rear of your car to record footage from your car’s point of view. It is used to record what is going on around and inside the vehicle. The recordings are usually looped, meaning that unimportant footage is written over by new footage. 

Most dashcams also come with various built-in sensors. These sensors can pick up changes in G-force. Therefore, if a car collides with yours, the incident will be recorded and saved to the memory card. It will also be locked to ensure that it is not written over or lost. You can review the footage later and save it or submit it to the authorities. 

Dashcams are either powered through a power outlet found in cars or through batteries. Some prefer a hard-wired dashcam because there is no fear of the battery running out of charge. Others prefer battery-powered dashcams because they always remain on and do not miss anything.

Once the camera is switched on, it starts capturing footage and saving it as video on a microSD card. If there is a collision and the dashcam has G-force sensors, it will flag the footage, and you can review it later. 

To review the footage, remove the memory card and connect it to your computer. From there, you can check the footage, copy it, delete it, etc. Nowadays, dashcams also come with additional features, such as Wi-Fi connectivity, that allow you to review your footage on a different device. 

Different Kinds of Dashcams

If you are in the market to purchase a dash cam, you have three different kinds to choose from. Your choice of dashcam should depend on the sort of features you want.

Basic Dashcams

Basic dashcams are designed to do the most basic job: capturing a video of the road in front of the vehicle. These dashcams are the most affordable and easiest to set up and maintain. Due to their price range, they have limited features and work on a simple loop recording setup. These cameras also do not have a lot of storage capacity.

Advanced Dashcams

Advanced dashcams are more expensive than basic dashcams but have more options and features. Most dashcams in this category have GPS functionality, accelerometers, speed sensors, and the ability to record audio. 

Some advanced dashcams also have thermal cameras to catch all movement around your vehicle.

These features allow the advanced dashcams to provide more security as you can capture more. Some advanced dashcams also offer an uninterruptible power supply, meaning that the dashcam will keep recording even if the car is off or the power shuts off for some reason.

Dual-Camera Dashcams

Dual-camera dashcams are also called interior/exterior dashcams. They have two cameras instead of one, which has added benefits. With such dashcams, you can monitor the inside of the car and the outside at the same time. An added camera angle allows you to protect yourself against theft and fraud. 

You can also use it to assess the driver’s state and warn them if needed to avoid any mishaps.

Features To Consider

When purchasing a dash cam, you must buy one with added features that will allow you to protect yourself better. Therefore, you must remember a few features before making your purchase.

Image Quality

Dashcams come with many features, but arguably the most important is their image quality. If the image quality is not up to the mark, you will not be able to use your dashcam to its full potential. 

When purchasing a dashcam, ensure that it has a high-quality camera. Such cameras produce better pictures, which can be instrumental if the camera records an accident. A sharper camera will help you see all the details clearly. 

The resolution of the camera is also essential in ensuring sharp images. It is often depicted through the number of vertical pixels on an image. Generally, the higher the number of pixels is, the better the camera and the image quality output will be. It would be best if you aimed to purchase a camera that at least has a 1080p resolution. 

Dashcams with better cameras are more expensive, but if you have the budget, you should aim to get one with 4K.

The frame rate of dashcams is also essential. As these cameras are designed to take videos, the number of frames they can capture per second is important. The standard frames per second are 30, and this fps is fine for most users. 

If you want something much smoother, opt for a camera that captures video at 60fps. It is important to note that videos taken at a higher fps will occupy more space. Therefore, you will run out of room quicker. 

If you are unsure of the fps you prefer, purchase one that has the option to change the fps. That way, you can lower the fps if you face storage issues. 

Viewing Angle

The camera’s viewing angle or field of view is how wide a camera can see. This feature can vary greatly depending on the camera and its lens. Dashcams that have a wider viewing angle are able to capture more. 

A greater viewing angle does have a few tradeoffs. The larger the camera’s view, the more the pixels spread out. This spreading can significantly affect the image quality and decrease it. Aim to purchase a dashcam with a large viewing angle but ensure it is not too wide. 

Gauging the viewing angles of dashcams is difficult because manufacturers fail to provide accurate details about them. Additionally, there is no standard measure, so each manufacturer measures it differently. Some offer a horizontal measurement, and some a diagonal one. 

The best way to see the angle is to find either actual footage taken from the camera or screenshots of the footage. Be sure to take note of the details on the side of the image and how detailed and sharp the overall image is. 


GPS is another helpful feature that makes dashcams more functional. They allow you to log the speed and location of your car alongside the footage it captures. The added information can be handy to avoid getting wrongfully fined or sued. 

A GPS feature in your dashcam also allows you to track the car and monitor driving habits. In case of an accident, You can evaluate who was at fault by locating the car and viewing the footage captured by the camera. 

Wireless Connectivity 

If you are in the market for a new dashcam, choose one with wireless connectivity. Such dashcams have apps that allow you to manage your footage and settings for the dashcam from your phone. Thus, you don’t have to pain yourself into trying to navigate through the small built-in screen found on most dashcams.

Internet connectivity also allows you to upload your footage to a cloud. This makes accessing the footage from your phone or computer a lot easier. You can download the footage and save it to view later. 

However, only some people need Wi-Fi capabilities on their dashcams; for most, Bluetooth connectivity will be enough.

Nighttime Recording

Night vision or low light vision is a beneficial feature to have in dashcams. They allow the camera to catch sufficient detail if an incident occurs when it is dark outside. Therefore, it provides protection even at nighttime. 

The footage may be less detailed or bright, but it should be good enough to capture text like a car’s number plate.

Some dashcams have a built-in battery to ensure that the dashcam always remains on. If you want your dashcam to stay on even when your vehicle is parked, you should purchase a dashcam with an inbuilt battery.
