A dash cam is a small device that mounts to your car’s windshield and records what happens outside of the vehicle, as well as capturing footage in the interior. It’s a popular choice for drivers because it provides real-time, straight-to-the-point proof in the event of an accident or other incident. Most models are simple to set up, use the car’s battery for power and provide a constant stream of recordings, allowing you to review video footage at your own convenience. Some can be connected to the internet, enabling you to share the data with insurance companies or other people in need of the evidence.

While you may be able to find a basic dash cam for around $50, the technology is constantly evolving and the higher end options are packed with features. Some are designed to record in HD, with dual cameras, and have a range of other security features such as motion sensors and parking mode. These can alert you to suspicious activity in and around your vehicle, as well as automatically start recording when a collision is detected. Others can be managed remotely from a smartphone, using voice commands to control the camera or transfer saved videos to the cloud for safe keeping.

Some of the most popular models even include GPS, allowing you to track your speed and location while you are driving. These devices can be especially useful for parents who are entrusting their teenagers with a car, as they can keep tabs on the driver’s movements and performance behind the wheel. For example, American Family Insurance’s teen safe driver program gives each participating teenage driver a free dash cam for one year and has them enrolled in a year of professional coaching to help them improve their driving.

Many of the top rated dash cams on the market are also designed with ease of use and low maintenance in mind. They’re usually very easy to install, using a variety of mounting solutions such as suction cups or adhesive pads. Most are also designed to automatically begin recording when you turn on your vehicle. Some can be hardwired into the car’s electrical system, using a special adapter that connects to the fuse box, so they’re always on and recording.

Lastly, the quality of the recordings from most dash cams is excellent. They can capture clear images in high-definition and offer a wide field of view that can make them an excellent option for anyone who is looking for a reliable camera to add to their vehicle.

While there is some privacy concern associated with dash cams, it’s important to remember that the device is only recording what is happening on public property, which includes roads. In some countries, such as Switzerland, privacy laws are so strict that this type of dash cam is illegal to use. In the USA, however, it is perfectly legal to have one in your vehicle. This is why so many motorists choose to invest in a dash cam, as it can be a powerful tool against insurance fraud and other scams.
