BlackVue is one of the most respectable companies out there selling top-quality dash cameras. A high-quality dash camera offers many features drivers will appreciate like the ability to record seamless video instantly, monitor your vehicle remotely while it’s parked, and save video files so you can easily access them. At first glance, the DR900X and the DR750X two-channel dash cams from Blackvue seem almost identical.
The similarities largely end at the way these two cameras look, so we are going to explain the differences between the two and let you know why we think the Blackvue DR900X-2CH is a better buy than the other model (>>> Find on Amazon).

How Does a Dash Cam Work?
A dash cam mounts to the inside of your windshield and captures video while you drive. Some camera systems can record full-time while others only capture video when sensors detect a reason to record. Dash cams with advanced tech can record video even when the car is parked. The best dash cameras even make it simple to view and download videos remotely by accessing cloud storage data.
What Does Two-Channel Mean?
You’ll find dash cams sold as one-channel, two-channel, and three-channel. This refers to the number of cameras included in the set. A single channel dash cam views only the front of the vehicle. Two-channel systems record front and rear, while a three-channel will also record inside the vehicle. Whether you purchase one system over another largely hinges on how you intend to use your cameras. In almost all cases, we recommend purchasing a two-channel system for the best recording and the highest level of protection.
Why Would I Want a Dash Cam?
A high-quality dash camera provides you with an extra layer of safety you otherwise are lacking. It’s an unfortunate fact that most drivers will be involved in an accident at some point in their life. Sometimes, these are minor fender-bender accidents that are easily resolved, but that isn’t always the case. About one-third of motor vehicle accidents involve significant injuries, many of which can be life-altering.
A dash camera records what happens just before and after a potential accident. The recording from a dash camera prevents insurance adjusters from using speculation to reduce the amount of liability the at-fault driver is responsible for. When a serious accident happens, your dash camera will make sure you can get the maximum fiscal recovery without complicated and expensive lawyers.
Sometimes It’s Just Fun
How many times have you been out for a drive and some wild and crazy driver does something so unbelievable, you wish you had it on video? Well, a dash cam makes it easy to show your friends and family your harrowing adventures. Often, a good-quality dash cam will give you great video footage of entertaining drives, like twisty mountain roads or blasting down a deserted stretch of highway that are just fun to share and watch.
BlackVue DR750X
Pros
- An ideal buy for the casual driver looking for a fun and simple camera to share videos with friends
- The lower initial cost leaves budget room for buying optional equipment
Cons
- Front camera image can be blurry
- Not a large enough price difference to beat out the upgraded model
BlackVue DR900X-2CH vs DR750X-2CH Features
These camera systems from BlackVue share some common features in addition to their nearly identical appearance. Both are Cloud-compatible, have built-in GPS and Wifi, and can connect via 4G LTE with additional equipment. That means you can remotely view video that has geo-location and other data, and you can do so with a high-speed internet connection. You get access to the BlackVue app for controlling the settings on your cameras with either of these cameras.
Both cameras can record video while the vehicle is parked. In order to get the most out of this feature, it’s recommended that you purchase additional equipment that includes a remote battery pack to prevent draining the vehicle battery.
The Big Difference
The biggest difference between these two cameras is the resolution each camera is capable of recording. It’s important to understand dash camera resolution and the terms the manufacturers use to describe their products. Before getting into the specs on these two cameras, we want to explain the terms we will use.
4k UHD vs Full HD vs SD
These are the most confusing terms manufacturers use to describe their cameras. To make this as simple as possible, resolution is measured in horizontal and vertical points. The larger the number of points in both directions provides smooth edges and can affect contrast, making images seem brighter and more realistic.
Standard-definition images are increasingly less common as HD technology has become less expensive. SD images are 4:3 aspect and 640×480 pixels per inch. This produces an image that is nearly square.
High-definition resolution is nearly universal today. It refers to images captured at 1280×720 (HD) and 1920×1080 (Full HD) pixels per inch with an aspect ratio of 16:9 that makes a rectangular, wide-screen image.
The highest resolution cameras today are using a standard called 4K UHD. This term is a little bit of sloppy advertising because 4K and UHD are not the same thing. Virtually all commercial cameras on the market today are UHD, with a resolution of 3,840×2,160 pixels per inch while 4k is 4,096×2160 pixels. 4K images have slightly different aspect ratio of 17:9 vs 16:9 ratio of Full HD.
BlackVue DR900X
Pros
- UHD camera with 8 MP sensor
- Great contrast and resolution when things happen fast
Cons
- High-resolution video eats up Cloud storage and SD card space
- UHD night recordings are a little dim, improves by reducing resolution to maximize light
How Resolution Affects Camera Performance
A higher aspect ratio offers a more clear image. In terms of dash cam technology, a higher resolution will make it easier to see fine details like license plate numbers. Should an image need to be enlarged, a higher resolution will make a big difference in image quality.
The higher the resolution of an image, the larger the file size is. Cloud storage is often bought per-megabit. Storing 4K images in the cloud can be as much as three times the expense of storing HD images. If you are using SD card storage on your dash camera, a 4K camera may fill a 32GB card in as little as a few hours, while an HD camera will record for much longer on the same card.
Sensors
The 900X and 750X use different sensors for the front cameras. The 900X uses an 8 megapixel sensor against the 2..1 megapixel sensor the 750X features. The difference in front sensor megapixels provides better color, contrast, and clarity for the 900X. This is a big deal and a key reason we select this as the best BlackVue camera because the better sensor captures smoother video with less motion blur. Our more in-depth review of the BlackVue DR900x
Both rear cameras in the two-channel set feature identical CMOS 2.1 megapixel cameras, so there is no difference to discuss. The rear cameras use the same Sony STARVIS for both the 900X and the 750X systems.
Framerate
Here is where things get a bit dicey. At UHD resolution, the 900X captures 30 frames per second. The 750X shooting at a lower resolution is capable of capturing 60 frames per second. Higher frames provide smoother video, particularly in low-light situations. The 900X can be set to record at 60 frames per second, but does so in Full HD resolution.
Our Pick: BlackVue DR900X-2CH
Despite the increase in cost for Cloud storage and the need to purchase a huge SD card, the image quality at high speeds is what sets these two apart. The image from the 750X is fantastic, and many drivers will be perfectly happy with the quality of recordings and how easy accessing files is. We like the 900X simply because you need a dash camera when things happen too fast to see, and an image distorted with motion blur isn’t nearly as useful when it matters the most.
Conclusion
Both of these cameras are top-of-the-line systems that will provide clear images and make it much easier for you to prove what happened in an accident. They are also a lot of fun for recording interesting drives or capturing weirdos on the road. We like the 8 megapixel UHD resolution of the front camera on the BlackVue900X-2CH enough that it’s worth the compromises large data files create. We think you will be happy with the 900X for years to come (>>> Check on Amazon).
