What is a video recorder and why should you buy one?
A dash cam is a small digital video camera and recorder that drivers can install in their cars. It continuously records the view of the road as seen from the front, side, or rear windows of your car.
There are many camera models on the market, including models that can capture the interior of your car and others that record audio.
What is the use of a video recorder?
The main advantage of a dash cam is enhanced protection. If you ever get into a collision with another vehicle, there will be no guessing about what happened and who was at fault. Having video footage on hand is evidence that will protect you in the event of an accident.
When it comes time to talk to the police, insurance companies, or lawyers - if that's what it comes down to - it will be helpful to have your own eyewitness to vouch for you.
Some cameras have a GPS feature for added security. If your car is stolen, you will have a much better chance of finding and recovering your vehicle.
Another benefit is that auto insurance companies often give discounts on their insurance premiums to drivers who have a dash cam installed in their car.

Which video recorder is better for use?
If you're going on a road trip, the Nextbase 622GW is the best camera you can buy right now. It combines the basics, with outstanding image quality and solid smartphone connectivity, while also offering features that aren't as common in the camera world.
The Nextbase 622GW boasts high video quality, excellent stabilization, and the inclusion of What3Words' surprisingly smart geolocation services. There's also integration with Amazon Alexa for voice control and app use.
The 3-inch rear touchscreen is crisp and clear, and the inclusion of What3Words is clever as it can alert emergency and crash services to your exact location, even when there is no Wi-Fi or mobile data available. The recent adoption of the What3Words standard by Australian emergency services is testament to its effectiveness.
The F800 is a multi-talented device. It comes with GPS tracking, safety camera and speed alerts, as well as safety alerts like forward collision and lane departure warning. There's built-in Wi-Fi, so you can connect to your smartphone.
There's even a time-lapse mode that will record your parked car for a full 48 hours if necessary - a great feature if you're worried about your vehicle being vandalized when you're out at night.

BLACKVUE DR900X
The front camera records in 4K resolution with an 8MP sensor, while the smaller rear camera shoots in Full HD (1080p). The front field of view is 162º, while the rear view is a slightly narrower 139º. Both cameras record video at 60 frames per second.
Wi-Fi and GPS are both included, and Blackvue also sells an optional 4G module to give the camera system a constant connection for remote messaging and live viewing. The data connection also allows for two-way voice calls, where you can talk to someone in your car remotely.
Both cameras have a cylindrical design, making them more compact than others, although the size savings come at the cost of the lack of a screen.
