M4 Quad Mirror Dash Cam, 1080P 4-Cam, 12" IPS Touchscreen


Description

The Acumen M4 Quad Mirror Dash Cam is a next-generation rearview mirror camera system engineered to deliver full-vehicle surveillance on city streets and rugged off-road terrain alike. Powered by a high-performance dual-chip image processor, it captures 4-channel 1080P Full HD video simultaneously - front, rear, and both sides - giving drivers a complete picture of everything around them. The starlight-grade CMOS front camera pairs a 7-layer glass lens with a 170° ultra-wide field of view, while WDR rear and side cameras cover 1.5x more ground than a standard mirror, picking up multiple lanes at once.

A 12-inch IPS touchscreen with 2.5D curved glass keeps the interface sharp and glare-free, and built-in 5.8G WiFi plus GPS make it easy to review footage, track routes, and share evidence directly from your phone. Whether you're a daily commuter, a fleet operator, or an off-road enthusiast, the M4 is built to handle the demands of real-world driving - day and night, rain or shine.


Key Features

  • 4-Channel 1080P Full HD Recording: Dual-chip processor drives simultaneous front, rear, and dual side-view recording in Full HD - total vehicle coverage with no blind zone left unmonitored.
  • Starlight-Grade CMOS Front Camera: 7-layer glass lens with a 170° FOV and advanced WDR plus 3D noise reduction delivers exceptional image clarity in low-light and nighttime conditions.
  • WDR 180° Rear and Side Cameras: 6-layer glass lenses with 180° ultra-wide-angle coverage capture 1.5x more of the road than a standard rearview mirror, spanning multiple lanes simultaneously.
  • Turn-Synced Blind Spot Display: Automatically displays and records the corresponding blind spot camera when a turn signal is activated - helping prevent collisions during lane changes and turns.
  • 12" IPS Touchscreen with 2.5D Curved Glass: Large, responsive display reduces glare and delivers a smooth touch experience for easy in-vehicle control.
  • 5.8G WiFi App Control: Connect your smartphone for real-time video previews, footage downloads, and sharing - no need to remove the SD card for emergency access.

  • Smart Parking Monitoring: Time-lapse 4-channel parking mode records up to 24 hours of coverage and locks collision footage automatically via the gravity sensor - essential for catching hit-and-run incidents.
  • Supercapacitor Power Design: Operates reliably from -4°F to 158°F with a 9V-30V input range, making it compatible across a wide variety of vehicle brands and types.

Why You'll Love It

The M4 gives drivers a level of situational awareness that a standard rearview mirror simply cannot match - four cameras, one clean integrated unit, zero external connectors cluttering your cab. Its all-in-one body is built to withstand high-frequency vibrations and extreme temperatures, making it equally at home in a daily commuter sedan, a heavy-duty pickup, or a fleet van logging thousands of miles a month. The turn-signal blind spot display is the kind of feature that quickly becomes something you can't imagine driving without, especially in dense traffic or on multi-lane highways. With 24/7 loop recording, gravity-sensor collision locking, and up to 24 hours of time-lapse parking monitoring, it's always watching - even when you're not. Backed by a 24-month factory warranty, a 30-day return guarantee, and around-the-clock customer support, the M4 is a purchase you can make with complete confidence.

FAQ

Will the M4 fit my vehicle?

The M4 is designed to fit most cars, trucks, and SUVs using the included clamp and rubber strap, which secure it over your existing rearview mirror. For specific vehicles like Jeep, Toyota, and Mercedes-Benz Sprinter, Acumen also offers precision-engineered vehicle-specific brackets sold separately for an even cleaner, more secure installation.

How does the turn-signal blind spot display work?

When you activate your left or right turn signal, the M4 automatically switches the display to show the live feed from the corresponding side camera in real time. This gives you an immediate view of the blind spot you're merging into, and the footage is recorded simultaneously - so you have video evidence if anything goes wrong during the maneuver.

Does the M4 work when the car is parked and turned off?

Yes. When connected via the included hardwire kit, the M4's parking monitoring mode activates when the vehicle is off. It uses time-lapse recording across all four channels for up to 24 hours, and the gravity sensor will automatically lock and save footage if a collision or impact is detected while parked - ideal for catching hit-and-run incidents in parking lots.

What SD card do I need, and does one come included?

The M4 ships with a 64GB Micro SD card right in the box, so you're ready to record from day one. If you need more storage, it supports cards up to 256GB. Loop recording ensures the camera continuously writes new footage, automatically overwriting the oldest files when the card is full - unless footage has been locked by the G-sensor.

How do I access and share my footage?

The M4 has built-in 5.8G WiFi that connects directly to your smartphone via the Acumen app. From the app you can preview live feeds, download saved clips, and share footage - all without removing the SD card from the camera. You can also use the included card reader to access files directly on a computer.

Is the M4 difficult to install?

No specialized tools or professional installation are required. The mirror unit attaches to your existing rearview mirror with the included clamp and rubber strap. Camera cables run to the rear and side cameras, and the hardwire kit connects to your vehicle's fuse box for clean, reliable power. The all-in-one integrated design means no external connector boxes or exposed wiring to manage. A full user manual is included, and Acumen provides tutorial resources on their website.
