The Best Single-Channel Cloud Dashcam

With its ultra-wide 162-degree view angle, DR900S-1CH catches all the action happening in front of your vehicle.
The 8-megapixel sensor produces spectacular 4K Ultra HD footage, letting you read license plates from farther away.
With H.265/HEVC (High-Efficiency Video Coding), the video files stay small so you can record for as long as a standard Full HD dashcam.
DR900S-1CH also features dual-band 802.11ac Wi-Fi for super fast file transfer to your phone.

Discover the 4K difference

4K in a dashcam is not a gimmick. It is a game-changer.
It is not about playing videos on a giant screen–although you could do that too. It’s about providing video proof.
A dashcam is only as good as its ability to capture crucial details–usually license plate numbers.
The 8-megapixel 4K UHD sensor does just that by capturing 4 times as many pixels as in Full HD.
And with its fast shutter speed, details are frozen in place.
Just pause and zoom in.

No need to sacrifice recording time

With bigger resolution come bigger files…unless you have better compression.

High Efficiency Video Coding (HEVC/H.265) is the standard in 4K video broadcasting and streaming.

With HEVC, you get great-looking 4K videos but same recording time as a regular Full HD dashcam.
Who said you can’t have it all?

Amazingly fast Wi-Fi transfer speed

Transfer files to your phone either fast or…very fast!
The dual-band built-in Wi-Fi of the DR900S Series allows twice faster transfer in 5GHz mode.

With BlackVue’s Sub-Stream technology, Quick Play versions of the videos are saved along the originals.

No more lengthy buffering when browsing videos over Wi-Fi or the Cloud!

Set up (easily) and forget

BlackVue dashcams are very easy to install. Attach the front unit to the windshield behind the rear view mirror with the provided double-sided tape.
This way, the dashcam is invisible to the driver’s eye. Simply plug the power cords into the cigarette lighter / accessory power socket of your vehicle and it will automatically start recording as you turn ignition on (no need to push any button).
Once set, you can forget about it, knowing it will reliably record your drive.

Parking Mode Support

DR900S-1CH can protect your car when you are away.
In Parking Mode, your dashcam monitors your parked vehicle, recording videos when it detects movement or impact. It also includes the few seconds before the triggering event, thanks to buffered recording. You will need a Power Magic ProPower Magic Battery Pack or Power Magic Ultra Battery to enable this feature. Find more info about Parking Mode here (link opens in new tab).

Secure Memory Management

Event Files Overwrite Protection:

Dashcams record in a loop, overwriting older files when the memory is full. BlackVue DR900S-1CH can prevent Event files (triggered manually or by impacts) overwriting. Up to fifty (50) files can be protected this way. You can choose to allow new Event files to overwrite past Event files, thus keeping the latest fifty.

Adaptive Format-Free File Management

This BlackVue-developed file system improves recording stability and requires less microSD card formatting.

Manage Videos Easily with the BlackVue App and Viewer

The BlackVue App (iOS/Android) and Viewer (Windows/Mac OS) are free to download and use.
Both allow you to change settings and review videos sorted by time and type (Normal/Event/Parking).
With the BlackVue App, connect via Wi-Fi to your dash​cam to retrieve videos on the spot.
