Sleek Protection for Your Ride

High-performance surveillance shouldn’t clutter your windshield. Momento M8 Ultra combines design and power with a compact footprint that measures at 5″ x 2″ and sits cleanly behind your rearview mirror.

Our Most Powerful Image
Sensor Ever

The Momento M8 Ultra integrates Sony’s next-generation STARVIS 2 image sensor, engineered specifically for high-performance surveillance and security in all lighting conditions. Paired with HDR image processing, the M8 Ultra delivers our clearest video quality to date.

Clear Evidence Day or Night

While standard dash cameras struggle with night time driving, the M8 Ultra features High Dynamic Range, or HDR, which processes multiple exposure levels simultaneously to handle dark streets and bright headlights in a single frame.

See Every Detail,
Front and Back.

Your Momento dash cam captures 4K UHD footage up front with enough resolution to document incidents for any insurance claim. The included 1080p rear camera provides complete coverage for hit and runs, parking events, and rear-end disputes.

Battery-Efficient Parking Mode

While other dash cameras drain your battery, Momento’s “ECO” parking mode utilizes radar to detect motion while the engine is off, resulting in a 90% reduction in current draw. The M8 Ultra is our first dash camera system to feature “ECO” radar technology on both front and rear cameras.

Front and Rear Dash Cam Coverage. Every Incident, Captured.

The M8 ULTRA records from front and rear so you have video evidence from every angle. Whether it is a rear-end collision, a false claim, or a hit-and-run, both cameras are running. Wide-angle lenses on both cameras capture more of the road. You’ll have the angles that matter when it counts.
