Aprilboy Mirror Dash Cam Review: The 3-Channel Resolution Trade-Off Explained

The Aprilboy 3-channel mirror dash cam replaces the view in your rearview mirror with a 9.66-inch touchscreen and records three cameras at once: one looking ahead, one watching the cabin with infrared LEDs, and one at the back of the car on a 33 ft cable. This Aprilboy mirror dash cam review is for drivers who like the idea of a big digital rear view, rideshare drivers who want the cabin recorded, and anyone tired of a windshield cluttered with gadgets.

Ivan, our editor, bought this Aprilboy mirror cam with his own money. Listings get revised over time, so this review covers the product exactly as it is currently listed rather than assuming anything about earlier versions. This review does not include any first-hand notes from Ivan yet, so nothing here describes results from the road; it is built from the listing's specifications and the general engineering of mirror dash cams.

The short answer: it is a capable layout with an honest catch. With all three cameras running, the front is 2880 x 1620, not 4K, and parking mode needs a kit that is not in the box.

Aprilboy mirror dash cam at a glance

Aprilboy is a marketplace brand without an official website that we could find, and the specifications below come from the current listing. Several numbers that serious dash cam makers publish, such as the image sensor, frame rate and operating temperature, are not given.

What's in the box

The listing includes the mirror unit with its cameras, a 33 ft rear camera cable, a 64GB microSD card, a car charger for the 12-volt socket, a card reader for viewing files on a computer, two straps to secure the unit over your existing mirror, and a 3M adhesive pad.

Two things are missing that matter. The first is the ACC hardwire kit for parking mode, sold separately. The second is any published maximum card size, so if you want more than 64GB, check with the seller before buying a large card, because a card above the supported limit may not work at all.

Mirror dash cam vs windshield dash cam: what changes

A mirror dash cam is a different kind of product from the windshield cameras that make up most of our dash cam coverage, and the differences go beyond looks.

What you gain. The windshield stays clear: the unit sits where your mirror already is, so nothing new is mounted on the glass. The screen is enormous by dash cam standards, roughly three times the diagonal of the 3.18-inch touchscreen on the BOTSLAB G980H. And the rear camera feed turns the mirror into a digital rear view, which helps when the back window is blocked by cargo, tall passengers or headrests, or when the rear glass is heavily tinted.

What you give up. A camera feed on a screen behaves differently from a reflection. Your eyes have to refocus from the road ahead to a display about two feet away, which takes a moment and gets harder with age. A 150° rear lens also makes following cars look smaller and farther away, much like a convex side mirror, so it takes practice to judge distance. There is no depth from moving your head, as there is with a real mirror. And glare or a bright screen at night can be distracting, so the brightness settings matter more here than on any windshield camera.

What to check in your car. The unit straps over the mirror you have, so look at what that mirror does today. Auto-dimming, built-in garage door buttons, compass or temperature displays and a microphone for hands-free calling may all sit on or in the mirror, and the strap-on unit covers them. Many modern cars also have rain, light or lane-keeping sensors in a housing behind the mirror; the mirror cam and its cables should not block that area.

Resolution: 2880 x 1620 in 3-channel mode, 4K only in 2-channel

This is the most important spec to understand, because the headline 4K figure only applies in one configuration.

With all three cameras connected, the listing gives the resolutions as 2880 x 1620 for the front, 1920 x 1080 for the cabin and 1920 x 1080 for the rear. In 2-channel mode, without the cabin camera, the front records at 4K with a 1080p rear.

In numbers, 2880 x 1620 is about 4.7 megapixels, and 4K (3840 x 2160) is about 8.3. So in 3-channel mode the front camera records a little over half the pixels it can manage in 2-channel mode. The likely reason is processing capacity: the camera's processor can only handle so many pixels at once, and the cabin camera takes a share of that budget. That is common on multi-channel cameras, and the four-channel BOTSLAB G980H makes the same trade, but it is something buyers should know before they assume 4K.

What it means in practice, on paper: 2880 x 1620 spread across a 170° lens should be enough to show the scene and the vehicles in it, but reading a plate on a car more than a short distance ahead is less likely than with a true 4K front. If plates ahead are your priority and you do not need the cabin view, run the camera in 2-channel mode. If you need the cabin recorded, accept 2880 x 1620 up front.

Aprilboy does not publish the frame rate for either mode, the image sensor or the bitrate. Those numbers decide much of the real-world quality, especially at night, and their absence makes it impossible to compare this camera's image chain with the STARVIS 2 cameras on our site on paper.

The cabin and rear cameras

Cabin camera with infrared

The cabin camera records 1080p across a 150° view and has infrared LEDs, so it can see passengers in a dark car. Infrared light is invisible or nearly invisible to the eye, so it lights the cabin for the camera without dazzling anyone, and the image becomes black and white in the dark. That is normal for infrared. The listing does not specify the wavelength or how many LEDs there are.

A cabin camera mainly serves rideshare and delivery drivers who want a record of what happens inside the car, and parents of teen drivers. If neither applies to you, the better choice may be to run without it and get the 4K front back.

Rear camera and the 33 ft cable

The rear camera records 1080p across 150°. The 33 ft (about 10 m) cable is generous: it is long enough to reach the back of a full-size SUV or the rear of a pickup cab with plenty of slack for routing around trim.

You can mount the rear camera inside the rear window or outside the car. Inside is easier and keeps the camera out of the weather, but it looks through tint and defroster lines, and the screen will show a strip of your own rear deck or cargo area. Outside, usually above the license plate, gives a cleaner view but means passing the cable through the body and sealing the hole. The listing summary we checked does not give a waterproof rating for the rear camera, so confirm it with the seller before mounting it outside.

Many mirror cams use a reverse-light connection to switch to a parking view with guide lines. The listing details we checked do not mention this, so do not count on it without checking the manual.

Viidure app, Wi-Fi and the specs Aprilboy does not publish

The camera connects over 5.8 GHz Wi-Fi to the Viidure app. Viidure is not an Aprilboy app: its App Store listing names Shenzhen Xiaozhen Technology Co., Ltd. as the developer, and it serves many dash cams and action cameras from different brands. That has two consequences.

First, features are generic. You get live view, playback, downloads and settings, but nothing designed specifically for this camera. The App Store listing also shows in-app purchases with one-year, two-year and permanent tiers, so some features sit behind a payment; check which ones before you rely on them.

Second, privacy. Viidure's App Store privacy label, which the developer reports itself and Apple does not verify, lists device identifiers among the data used to track you. If that concerns you, you can still use the camera without the app, by reviewing footage on the mirror or reading the card on a computer with the included reader.

The 5.8 GHz band is the right choice for moving large files. A 5 GHz connection is generally several times faster than 2.4 GHz at short range, which matters when a minute of three-channel footage runs to hundreds of megabytes.

Beyond the app, these specs are not published in the listing details we checked:

• Image sensor and frame rate for any channel.
• GPS, which matters for speed and location data in an insurance claim.
• Power backup type. Supercapacitors tolerate heat and cold better than lithium batteries; without knowing which this unit uses, owners in hot or very cold climates cannot judge it.
• Operating temperature range.
• Maximum card size.
• Warranty terms.

None of these is a reason on its own to avoid the camera, but together they mean you are buying on a shorter spec sheet than with VIOFO, 70mai or BlackVue.

Parking mode needs a separate ACC hardwire kit

The listing describes a 24-hour parking monitor, and it is explicit that it needs a separate ACC hardwire kit. Plugged into the 12-volt socket with the included charger, the camera records only while the socket has power, which in most cars means only with the ignition on.

An ACC hardwire kit connects to the fuse box with three leads: one to an always-live fuse, one to an ignition-switched (ACC) fuse that tells the camera you have parked, and a ground. Three points to check when buying it:

1. Connector. Buy the kit the seller lists for this model so the plug fits the camera's power port.
2. Low-voltage protection. A good kit cuts power before the battery drops too far to start the car. Look for a published cut-off voltage, ideally adjustable.
3. Fuse taps. Make sure they match your fuse box, whether standard, mini, low-profile mini or micro.

The listing does not say how the parking monitor behaves: whether it records on impact, on motion or as a time-lapse. Check the manual before relying on it. For a step-by-step guide to fuse-box wiring, finding switched and constant fuses and routing cables safely around airbags, see our BOTSLAB G980H hardwire kit guide; the method is the same for any three-lead kit.

How to install a mirror dash cam

1. Bench-test first. Connect the rear and cabin cameras, power the unit from the 12-volt socket, and confirm all three views and the touchscreen work before you route anything.
2. Set the clock and format the card in the camera, then choose 3-channel or 2-channel mode depending on whether you will use the cabin camera.
3. Strap the unit over your mirror. Center it, tighten both straps evenly, and use the 3M pad where the instructions call for it. A loose fit lets the screen vibrate and the front view shake.
4. Check the front lens view. It looks through the windshield from behind the mirror, so make sure it sits inside the wiper sweep and is not blocked by the dotted ceramic band or a tint strip at the top of the glass.
5. Route the power cable up into the headliner, across to the A-pillar and down to the 12-volt socket, keeping it behind any curtain airbag rather than across its face.
6. Route the rear cable along the headliner to the back of the car, through the rubber hinge boot on a hatchback or SUV, and to the rear camera. Leave a slack loop at any moving joint.
7. Aim the rear camera with the mirror screen live, so the image covers the lane behind with a sliver of your bumper for reference.
8. Position the cabin camera, if used, so it sees the seats rather than the headliner.
9. Set the screen brightness and screen-off behavior before your first night drive.
10. Add the ACC hardwire kit if you want parking monitoring.

Aprilboy mirror dash cam vs 70mai T800E, VIOFO A329S and BOTSLAB G980H

Ivan bought several multi-channel cameras, and this comparison is on paper, from each maker's published specs.

The 70mai T800E is the most direct alternative: the same front, cabin and rear layout, but with a 4K front while all three channels run, a published F1.55 aperture, a supercapacitor rated 14°F to 140°F (-10°C to 60°C) and a mainstream brand's app. You lose the big screen and the digital rear view.

The VIOFO A329S is the image-quality pick on paper: STARVIS 2 sensors on all three channels, a 2K cabin and rear, and SSD storage up to 4TB. It mounts on the windshield rather than over the mirror, needs a hardwire kit for parking mode just as the Aprilboy does, and has no rear-view display.

The BOTSLAB G980H covers more of the car, with two side cameras, and has its own touchscreen, though a much smaller one. If you like a touchscreen but not a mirror cam, the REDTIGER F7N Touch pairs one with a 4K STARVIS 2 front and voice control.

Who should buy the Aprilboy mirror dash cam

• Drivers whose rear window view is often blocked, by cargo, child seats, tall passengers or dark tint, and who want the screen as a working rear view.
• Rideshare drivers who want front, cabin and rear recording in one unit, with infrared for night pickups.
• Owners of large SUVs, vans and pickups, where the 33 ft rear cable avoids extension cables.
• Anyone who hates windshield clutter and prefers one device in the mirror position.

Who should skip it

• Drivers who want 4K front video while recording the cabin. In 3-channel mode the front is 2880 x 1620.
• Spec-sheet buyers. The sensor, frame rate, GPS, temperature range and maximum card size are not published.
• People who want long-term support, such as a brand website, documented firmware updates and clear warranty terms.
• Drivers who find screens hard to focus on quickly, including many people with reading glasses; a reflective mirror needs no refocusing.

Tips and common mistakes with mirror dash cams

• Decide between 3-channel and 2-channel mode deliberately. Running the cabin camera when you never review its footage costs front resolution for nothing; the listing does not say how to switch modes, so check the manual.
• Upgrade the card carefully. Three channels fill 64GB quickly, but confirm the maximum supported capacity with the seller first.
• Check the straps after the first week. Straps can loosen as they settle, and a loose unit vibrates.
• Keep the screen dim at night. If the camera offers a screen-off timer, first check that the glass works as an ordinary reflective mirror when the screen is dark, because the unit covers your original mirror.
• Clean the windshield behind the mirror. The front lens looks through a patch of glass you never see from the driver's seat.
• Download important clips promptly to your phone or computer rather than relying on the card.
• Check the date and time after any long period without power, so footage carries a correct timestamp.

Final verdict: is the Aprilboy mirror dash cam worth it?

The Aprilboy 3-channel mirror dash cam is worth considering if the screen is the point: a 9.66-inch digital rear view that sees past cargo and passengers, plus front, infrared cabin and rear recording, with nothing new stuck to the windshield. The 33 ft rear cable and 5.8 GHz Wi-Fi are practical touches.

Go in knowing the limits. The front is 2880 x 1620 whenever the cabin camera runs, parking mode needs a separate ACC kit, the Viidure app is generic with paid tiers, and the brand does not publish the sensor, frame rate, GPS or temperature specs that would let you judge it fully. If image quality and documentation matter more than the big screen, the 70mai T800E or VIOFO A329S are stronger choices on paper. For every dash cam Ivan bought, see the Car Upgrades hub.
