Overall rating: 4.9 / 5 from 14 reviews.
I put it in my Sprinter van, and it's been a game-changer. Blind spots are a big issue. Having the side camera really helps with visibility -but with the M4 Quad's four-channel recording, I now get front, rear, and both side cameras all at once. It records every angle simultaneously and loops seamlessly, so I never worry about missing footage. Plus, its crystal-clear night vision and smart screen-memory feature (it goes back to the last view after reversing) make it completely hassle-free.

My vehicle didn't come with a factory rear view mirror, and the Acumen M4 QUAD turned out to be exactly what we needed. We purchased the M4 QUAD along with an extra 18-foot extension cable, since the original 32-foot one was just a bit short. We also got a mirror mount separately. The video quality for both rear and side views is excellent. The always-on rear view greatly enhances safety, and the side cameras-automatically activating with the turn signals-are a fantastic feature for improving lane-change visibility and reducing blind spots.

Great. I've had mine for 2 months. Night vision is SUPER great!!! And loop recording makes it totally carefree-just start and go. The touch screen is awesome-no need to press a bunch of buttons.
A while back I got rear-ended, and the cam caught everything clearly. It saved me a huge hassle-proved the other driver was on his phone. Crystal clear video.
What really blew me away is the dusk performance. When the outdoor light starts to fade, the mirror screen stays brilliantly bright, with vivid, pleasing colors that make every detail pop even in dim evening light.
One of my favorite features is the side cameras syncing with the turn signals. Every time I signal, it shows a clear side view, which really helps with lane changes and blind spots-super useful!
Overall, for the safety and peace of mind it gives, this is a solid five-plus stars.

I first purchased M3 in 2021 and it lasted me for 3+ years. I was contemplating if I should upgrade because the M3 was still good in use. I decided to upgrade to the M4 QUAD because of the blind spot detection and the side camera. It allows me to be more alert of my surroundings and really helps me with my parallel parking! I can now see if anyone had door-ding my car. The best part is the wifi connection that I did not have with the M3. The download speed to my phone is so fast. It literally downloaded in a few seconds! I am very pleased with this product and gives me more security and assurance that I would be able to video on all 4 sides of my car!

I love this M4 Quad, I got this mirror this past week as a gift. It really enhances my side view blind spots when I changed lanes. Especially on the freeway! I was side swiped last month and the person fled the scene. If I had this back then I would have gotten the person! I tried many other brands of the mirror dash cameras but they are not as clear and wide angled as this one! It really captured the license plate even at high speed. This is the only camera that really makes me feel safe when I change lanes. I am def gonna refer this mirror to everyone.

I opted for the adapter that replaces the stock mirror so this setup has a clean, factory look in my truck.
The options are awesome!
You can tilt the rear view with the touch screen,
Easily snap pics from the front or rear,
Comes with an SD memory card,
And the picture is so sharp, I now rely entirely on the camera for rear view.
What really impressed me are the side cameras that automatically activate with the turn signals. They make lane changes so much safer and help eliminate blind spots from both sides.
No more blind spots while driving-this system covers everything!You can easily snap pics front or rear
Includes SD memory card
The picture is so nice ,you will ONLY use camera for rear view!
No more blind spots while driving!

Got the mirror the image s are great
Having some some issues
1. Mirror won’t restart automatically , have to power it manually
. Did complete reset 2x
. Still wont start up auto
.It works fine once in awhile ,but most time it fails
2. Your app once activated and set on WiFi and working
. Turns my Apple car play off, on my brand new 2026 Pioneer Sphera 8000nex
. Car play works perfectly and so does the head unit
If I remove the mirror from my WiFi, the head unit works again
3. Rear back up cam Cannot adjust parking lines in close enough so they are 2-3 ft from the objects I don’t want to hit. My car is an FJ cruiser camera is mounted center of the spare tire, like OEM , I’ve tilted the camera down very far, no I cannot see the rear bumper or trailer hitch, so I try adjust back line but the will not move down ward any further . The camera is mounted at the OEM location center of the spare tire
Love it but need these issues fixed
