There are two main types of dash cameras. Single-channel and dual-channel dash cams, also known as dual dash cams. The word “channel” refers to the number of cameras used. Which one should you buy?
For SUVs and other personal cars, having two cameras provides better coverage. Sometimes the accident happens from the sides or from behind you. A dual dash cam arms you with evidence of what happened both in front and behind you.
One of the biggest benefits of this setup is how easy it is to use. You can easily access the footage from both cameras at the main station. This makes it less of a hassle to get the proof you need.
Because it uses the same time signature, it’s very easy to line up the two pieces of footage. With this feature, you can make sure that you are seeing the complete picture of what happened.
Some people believe that buying two single-channel dash cams instead of a dual dash cam is a better solution. They think that installing one in the front and one in the rear of the vehicle is less of a hassle.
The first argument is that, usually, the rear camera from a dual dash cam set has a lower resolution. You can actually look for a dual dash cam that has the same resolution for both its cameras.
The biggest downside of this idea is that single-channel dashcams are not designed for rear mounting. You will have to get very creative to properly mount it. You will also need a separate 12-v power supply. This means you will have to invest in a power supply as well.
What is a Dash Cam?
A Dash Cam is a camera that can be used to continuously record the view through your windscreen. It can be easily mounted on your dashboard or directly to your windshield. They’re used as a discreet eyewitness to everything that happens in front of you.
Dual Dash Cameras feature a second camera that can be mounted on the rear of your vehicle. It’s connected to your dashboard camera and the cigarette lighter power supply. This way you can have better coverage of everything that happens while driving.
Every driver should have a dashboard camera. They can arm you with concrete evidence in case of an accident. However, if you can afford, dual camera systems provide the best coverage.
