Why Dashcam Resolution Matters

Dashcam Resolution

One of the key specifications you should look at when buying a dashcam is its resolution specification. Resolution refers to the number of pixels that the video camera records. This specification directly translates to how much usable detail the system offers. If you witness dangerous driving or an accident, being able to provide accurate information about the parties involved is crucial. In this article, we’ll compare images from dashcams from AccFly and Mio and the flagship product from BlackVue.

What Is Field of Vision?

In talking to consumers, it appears that some people get confused by the difference between the camera’s field of vision and its image resolution. Field of vision describes what the camera sees and is specified as an angle from the center of the lens. With a higher field of vision specification (also called viewing angle), the camera can see farther to the sides of the vehicle. Here are a few examples.

Dashcam Resolution
This inexpensive camera has a field of vision specified as 120 degrees. You can see the first third of the car door on the left side of the screen and half of the sign on the right. Note the presence of the lens flare in the lower left corner of the image and the poor contrast of the text on the main shopping plaza on the right.

 

Dashcam Resolution
The DR900S-2Ch has a field of vision of 136 degrees. You can see most of the car door on the left and all of the sign on the right. Almost the entire dash of the car is in the image. Impressive! High-quality optics prevent light reflections within the camera and prevent lens flare. Advanced exposure compensation makes the sign information much clearer.

What Is Dashcam Resolution?

Resolution refers to the number of pixels contained in an image. More pixels mean that more detail and information can be captured. You can never have too much resolution.

Dashcam Resolution

In our comparison, we’ll look at our three cameras and compare cropped images of the back of the school bus to the left of the master image.

Dashcam Resolution
The writing on the back of the bus is illegible. You can only just make out the last two numbers of the bus number and the license plate is completely blurred.

 

Dashcam Resolution
Stepping up to the 1296p resolution of the Mio makes the bus number legible. You can almost make out the license plate number.

 

Dashcam Resolution
The 2160p resolution of the BlackVue DR900S-2CH makes reading the writing on the back of the bus very easy. Not only can you read the bus number and license plate, but the writing on the door is also legible.

Dashcams Are a Great Safety Investment

The motivation for this article came from a friend who was in a sideswipe accident. The car that hit him kept on driving. Although his dashcam recorded that it was a blue Honda sedan, he couldn’t read the license plate, and the police were never able to find the owner.

If you are shopping for a dashcam, choose one with great optics and a high-resolution image sensor. You only get one chance to record details like a license plate. Drop by your local specialist mobile enhancement retailer to find out what is available for your vehicle.

Testimonials

Best Experience!

I went into Area 41 today to upgrade my subs and the salesman spent a long time with me and didn't rush me I really appreciate that I was able to listen to different systems in different cars. I was able to get a whole system that is a lot better than just getting the subs I came in to ask about thank you

I Love This Place!

I love this place! Very knowledgeable staff and they installed one 12 that sounds like 2 for cheap. They also took the time to make sure that the car looks like it does before the installation so you can't even tell anything was touched. If you want awesome car audio come here!

Awesome Staff

Awesome staff and very precise with details. Long wait but they have a comfortable atmosphere and make you feel at home so the wait wasn't bad at all. Will be taking my other car for them next week. I highly recommend them!
