AZDOME M300S Dashcam: The Discreet 4K Camera That Never Leaves the Windshield
Some cameras sit on the windshield like a gadget; the M300S is easily forgotten. Designed for hidden mounting behind the rearview mirror, this front and rear car dashcam records the road in 4K and the rear simultaneously, with ADAS assistance, built-in GPS, and AZDOME voice control. You won't notice it after three days—but it sees everything, and a 64 GB microSD card is included so you can get started right away.
F1.8 Lens and GC4653 Sensor: What the M300S Captures on the Road
The 150° field of view covers all three lanes of a highway without distorting the edges, and the F1.8 aperture lets in enough light for the dashcam's night vision to remain usable under moderate urban lighting. The GC4653 sensor, powered by a Novatek processor, delivers 8 megapixels at 30 frames per second—enough to capture a license plate at highway speeds.
The H.264 MP4 format makes files directly readable on any computer or phone without a converter. It's a detail you don't think about until you need to send a clip to an insurer within the hour.
Internal GPS, Supercapacitors, and AZDOME M300S Voice Control
Three technical features set this discreet dashcam apart. First, the built-in GPS: every clip is time-stamped and geolocated, with speed recorded. Next, supercapacitor power instead of a lithium battery: this is what allows a camera to survive a summer behind a windshield in direct sunlight, where a battery would swell. Finally, voice control, which locks a file without you having to let go of the steering wheel.
Built-in WiFi connects the device to the AZDOME app: you can retrieve a video directly on your phone without removing the card. ADAS rounds out the package with lane departure and collision warnings.
- 4K Front and Rear Recording — two lenses powered by a single unit
- 64 GB microSD Card Included — the 4K dashcam is ready to use right out of the box
- Supercapacitors — no battery to swell, significantly better heat resistance
- Time-Stamped GPS and Speed — every file includes the location, time, and speed
- Voice Control — lock a clip without taking your eyes off the road
- Hidden-Style Mounting — for a discreet car dashcam, invisible from the outside
Installing the M300S: Windshield, Rear Cable, and Parking Mode
The main unit sticks to the top of the windshield behind the rearview mirror, where it remains out of the driver's field of vision. The rear camera connects to the rear window via a cable routed under the trim. For a dashcam installation with no visible wiring, allow an hour and a plastic trim removal tool. The version with a wiring kit allows you to go further: connected to the fuse box, the camera continues to monitor the vehicle with the engine off.
Does a Dashcam Drain the Car Battery?
When powered through the 12V socket, no: the power is cut at the same time as the ignition. The issue only arises if you activate parking surveillance via the wiring kit. This kit includes low-voltage protection that stops recording before the battery gets too low. This is the most common answer regarding a car dashcam with parking mode: properly installed, it won't leave you stranded in the morning.
