The 4K A900 Set Dash Cam from 70mai is their latest non-flagship product. It is the ideal tool if you want to keep your car safe whenever you are out and about or parked during the day or overnight. The recording quality is out of this world, and it offers dual 4K resolution, impressive nighttime and poor-weather recording, and an array of impressive features to keep your vehicle safe.
I was given a hardwire kit to ensure that my dash cam worked 24 hours a day. This simple-to-install feature allows you to make the most of the full security features. Alternatively, you can run it from the car battery when you are driving. I recommend hardwiring it for the ultimate peace of mind. It is easily done, or you can ask a professional to quickly wire it in for you. The cameras are ridiculously small, even if the display screen is an impressive 3 inches long. This allows you to check on your footage before sending it to your device via the built-in 4G connection.
The app is intuitive and easy to handle. Therefore, anyone can master this dash cam set without having to ask for help or feeling like you are a hindrance to your neighbours. Finally, installing it was a walk in the park. It took me no time at all, and inexperienced users will need under an hour to get themselves sorted out.

Technical aspects.
The most important aspect of a dash cam is its ability to record with ease. The 4K A900 Set Dash Cam has voice commands to capture any footage you deem important. Furthermore, it auto-records any incident for up to 3 minutes and 10 seconds before anything occurs. This is fantastic as it removes any doubt if you need to provide the evidence to the police or your insurance company. Alongside this, the footage is locked until you choose to wipe it. This prevents you from accidentally wiping key evidence.
Both cameras have a F/1.55 Aperture for improve lighting. This is essential during low-light events, nighttime, and other poorly lit moments. The result is crystal-clear recording that highlights anyone involved, car registrations, and key locations. This is supported by the built-in GPS. This captures your speed and the location of any accident. This helps to support you in the case of a 50/50 split, he said/she said incident.
The upgraded 4G compatibility helps users to enjoy a stable and quicker connection between the main unit and your phone or tablet. This is important if you need to transfer data and you are short on time. Additionally, no one wants their footage to become corrupted when they are moving it from one device to another.

Usability.
Installing the 4K A900 Set Dash Cam was a walk in the park. The smaller frame of the cameras ensures that they are simple to handle. Furthermore, they do not distract you once you’ve mounted them. I found it easy to hide the cabling within the trim of my car. You could hide it under the carpet as well if you don’t want to move the rubber trim pieces. Either way, you’ll be left with a clean and professional finish.
Wiring the devices was a cinch, and keeping it powered using the hardwire kit was a straightforward task. I’m reasonably tech-savvy, so I wasn’t concerned. However, an auto technician would help for a small price if you don’t want to mess with the electrical components of your vehicle.
The free-to-download app was quick to download and intuitive to use. Finding your recordings was simple, and all your important items are nicely hidden in their own folder. This was great as it prevented you from wiping any key footage.

Recording quality.
I was impressed by the high-quality recording feature. The dual 4K resolution is supported at up to 30 FPS. This may seem low, but it works well with this camera set, and I wasn’t disappointed by the video quality or the flow of each recording. You can adjust this in the settings if you want increased frame rates at the sacrifice of resolution.
The smooth recording continued during poor weather and low-light recordings. The cameras never faltered, and I had no issues with a setting sun, rain, or reflections from headlights or puddles. Even when it was pitch black, the impressive sensors and the large aperture worked in sync to capture razor-sharp and clean images/footage.

Build quality.
70mai has created a fine pair of cameras that are sure to last the test of time. The built-in supercapacitor can withstand high temperatures and freezing moments. The result is a device that’ll keep working even when the conditions spike. This is extremely reassuring when you consider the baking summer we’ve all endured. This heat resistance extends to the case and the mounting materials.
You don’t need to worry about the sticky mount falling off when sitting in the heat or the cold. Moreover, it will not fall from its mounting point when you are driving along. If you need to move your camera, you can remove the mount with the tool and use one of the fresh stickers to create a strong bond to the car.
Is the 4K A900 Set Dash Cam worth it?
I’ve reviewed the ULTRA set of this camera, and I was extremely impressed. However, it is more expensive than the 4K A900 Set Dash Cam. Therefore, if you want high-end quality at a more affordable price, this is the dash cam set for you. It is durable, easy to handle, and it looks great. Additionally, the recording quality is second to none, and I love the safety features. Accordingly, it is amazing, and I recommend buying it here!
