Dash cams are increasingly popular devices for recording what goes on from a car window and showing the driver’s point of view. The market offers quite a variety of dash cams, with different sizes, features and prices. But one thing that is common among all dash cams is video quality. That’s why we’ve taken some time to dig into the subject so that you can make an educated choice before buying your next device.
The first thing you need to understand is the difference between front and rear dash cams and how it impacts video quality.
Front dash cams
Front cameras are mounted on the dashboard in a car or truck, facing the driver and providing an unobstructed view. Because of the proximity to the windshield and the fact that they are tilted downwards, they have a very high field of view. This makes them ideal for capturing everything happening on the streets while driving. Front cameras have a wider field of view (FOV).
Rear dash cams
Rear dash cams are mounted upside down on the rear-view mirror and face the windshield. They have a vast area of view but are not very good at capturing small details. Rear cameras can capture more details and have higher resolution.
4K at 30 fps:
With 4K recording at 30 fps, a dash cam can capture four times more pixels than standard resolution video. One of the best things about this technology is that there’s enough data to create a high-quality backup for your video.
4K at 60 fps:
4K at 60 fps is a handy feature for drivers who drive in areas with fast traffic or who travel on highways most of the time. The higher resolution allows you to record license plates from far away, making it easier for you to identify people involved in accidents if the need arises.
2K at 60fps:
2K at 60 fps is great for all kinds of driving conditions. It will give you clear footage at any time of day or night, so you’ll never lose the details of an accident.
4k video at 30 fps or 2k video at 60 fps. Which one is better?
The decision between choosing 4k at 30 fps or 2k at 60 fps depends on your needs and preferences. If you want more action to be captured in a video without slowing the footage down, choose 4k. On the other hand, if you’re going to get more details and record license plates from a distance (during traffic stops), it’s better to choose 2K.
We’ve also noticed that most cameras with pre-installed GPS can only record 4k at 15 fps or lower, so if you are planning on using your dash cam for evidence in an accident, make sure it can record at least 720p HD resolution (at 60 fps).
Video Quality Testing Methods:
To understand how dash cam video quality is tested, you need to know the difference between 4k and 2k video testing. Different test methods show the average data rates at which your device can record video and store it.
Average data rates:
The number you choose to show is the average data rate of your device. That means that if you know how much memory it has, you can calculate its maximum video quality. However, this type of test isn’t 100% accurate, which is why most manufacturers only use it as a reference rather than relying on them completely.
Frame rate test ( fps test):
The number you choose to show is the average frame rate of your device. This will be a little bit difficult to understand, but it’s actually much easier to use than average data rates. The frame rate is how many images are captured per second, and the higher the number is, the better quality your video will be.
Best Video Quality for Capturing License Plates:
If you are looking for the best video quality to see license plates clearly, choose a 2K video. Although the higher resolution does not always mean better video quality, when it comes to dash cams, it does.
• Resolution: 2K
• Frame rate: 60 fps (frames per second)
• Average data rate: 100 Mbit/sec or more
Is 30 Fps Enough for a Dashcam?
4K video captures four times more detail than standard resolution dash cams. However, you have to remember that many compressions go on during recording at 4k. Although you’ll be getting the best quality for your money if you only record in 4k, it will take up a lot of memory space and be more challenging to edit. If you don’t need to do high-quality editing or don’t have the resources to handle the high data transfer speeds, we recommend choosing 2K at 60 fps.
However, we will tell you the top three 4k and 2k cameras so you can make a wise decision.

Q: Which one is cheaper, 2k dash cam or 4k?
A: 2k dash cam is cheaper than 4k dash cam.
Q: How much memory does 2k or 4K camera have?
A: Maximum memory depends on the micro sd card how much you insert in your camera. Sometimes 1TB or less than that.
Q: Which one should we choose, 1080p or 1440p?
A: 1080p is perfect for customers who want a clean and clear video without any obstructions nearby. 1440p provides you with significantly better quality by capturing more detail and using 1/3 less space.
Q: Which camera offers a wider view?
A: 4k cameras have a more expansive view up to 170°. 2k has the same 180°.
Q: What is the difference between a 5-star and 4-star camera?
A: 5 stars means that experts have inspected the camera to make sure they are working properly. Each one is looked into in 360 degrees, from all angles of a check, so that it can be better than before. The others are looked at up to the point where they have been used in normal conditions by people who had no idea that they could be fixed or brought back to life. They are thrown away without being checked at all, so there is no improvement.
