What I tested and how I set it up

I installed the Sherum dash cam in two vehicles over a week: a compact hatchback for daily commuting and a midsize SUV for a weekend road trip and some overnight parking tests. The unit I received included a 32 GB microSD card, a 12V power cable for the cigarette lighter, and a basic suction-cup mount. Installation was straightforward if you’ve routed dash-cam cables before: stick the mount behind the rearview mirror, run the power cable along the headliner and down the A-pillar, then tuck it to the center console. No hardwire kit was included, so I tested parking mode using both ignition power (for short stops) and an auxiliary power outlet that stays live when the car is off.

This is a dual-lens design in a single body: one lens faces forward, the other faces the cabin. The front lens captures 1080p footage with a wide field of view; the interior lens covers most of the cabin and does its best in low light thanks to the camera’s “starlight” sensor tuning and exposure compensation. The menus are navigated by small hardware buttons on the side and face of the device, and the interface lives on a compact LCD.

Design and mounting

The camera body is light and unobtrusive. The suction mount is tight and didn’t budge once I found the right spot, but fine-tuning the angle took patience. The mounting arm rotates and tilts enough for most windshields, yet the joints felt stiff out of the box; that’s good for stability, not so great for quick adjustments.

A few practical notes:
- Place it high and centered to keep it out of your field of view.
- Aim the cabin lens slightly downward to catch both front seats without too much windshield glare.
- Take a moment to clean the glass before mounting; that suction cup appreciates a spotless surface.

Video quality in the real world

Daylight footage from the front lens is solid at 1080p. License plates are readable when traffic is moderate and the lighting is favorable. The dynamic range is decent; it won’t match higher-end HDR cams, but it handled sunlit streets and shaded overpasses without crushing shadows or blowing highlights too badly. The cabin lens is understandably softer than the front view. During the day, faces and seatbelt use are easy to make out. At night, it relies on ambient light from the dash and streetlights. There’s no obvious IR illumination, so you get a grainy, boosted image in very dark cabins, but it’s still useful for context and events close to the lens.

Night driving is where the “starlight” tuning earns its keep. Headlight flare is controlled reasonably well, and signage remains legible. Fast motion in very low light pushes the limits of 1080p; plate capture becomes hit-or-miss at highway speeds under poor illumination. That’s expected in this price and resolution class. On balance, I’d call the night performance better than average for 1080p, with usable evidence capture.

Audio is clear enough to catch conversation in the front row and road noise. Windshield wiper thumps and turn signal clicks come through, but the mic doesn’t overload easily.

Loop recording, storage, and file handling

The included 32 GB card came preformatted and worked immediately. The camera supports up to 64 GB; that’s modest by today’s standards, but workable if you rely on loop recording. With both channels enabled, expect roughly 2–4 hours of rolling history on a 32 GB card depending on bitrate and settings. The device creates separate files for the front and interior views in synchronized time slices, so you’ll see paired clips per interval.

Loop recording was seamless in my testing. Older clips were overwritten automatically except for “locked” files flagged by the G-sensor. I recommend:
- Format the card in the camera on day one.
- Set loop length to 3 minutes for easier review.
- Keep G-sensor sensitivity at Medium to avoid locking too many files on potholes.

G-sensor and incident capture

The G-sensor does what it should. Hard braking and potholes on High will trigger locks too often; Medium struck a good balance for me. When a jolt is detected, the current clip is protected from being overwritten. I tested gentle taps and a simulated bumper nudge in a parking lot; both triggered a lock without freezing the UI or corrupting the file.

Parking monitoring

Parking mode is motion-triggered and can also use G-sensor events. Two important caveats:
- You need constant power for true 24/7 monitoring. Many 12V sockets cut power with the ignition off, so a hardwire kit to an always-on circuit (ideally with low-voltage protection) is the right way to run this.
- Sensitivity matters. On High, passing headlights and wind-shaken branches can trigger recordings. Medium worked better facing a quiet residential street; Low was preferable in a busy lot.

When powered, the camera wakes quickly on motion and saves short clips. You don’t get the full pre-buffered capture that more expensive systems offer, but it’s sufficient for documenting contact or suspicious activity near the car.

Live view and dual-channel behavior

Live view defaults to the front camera. You can toggle to the cabin view or a picture-in-picture overlay with a button press. It’s not the most intuitive implementation; the iconography is small and the sequence of views isn’t always obvious the first time through. The important part is that both channels record simultaneously even if you’re only seeing one view on the screen. In playback, each interval yields two files for synced review.

I would have liked an option to keep a persistent split-screen or larger PIP window, especially when ridesharing or monitoring passengers. As implemented, it’s workable but minimal.

Interface and day-to-day usability

This is where the Sherum demands a little patience. The buttons are tiny, labels are small, and the menu language occasionally reads like a literal translation. After a few passes, muscle memory takes over, but if you’re expecting a polished, smartphone-like interface, you’ll be disappointed. A few tips to save time:
- Format the card in-camera; third-party formatting sometimes caused an initial error prompt.
- Set Date/Time and Time Zone before your first drive so timestamps are accurate.
- Turn on screen timeout to minimize distraction and heat buildup.
- If you prefer quieter operation, disable key beeps.

Once configured, it boots quickly with ignition power and starts recording without fuss. I didn’t experience random reboots or card errors with the included media after formatting.

What’s missing

• No GPS: There’s no built-in GPS or speed stamping. If you need location and speed metadata for insurance claims, you won’t get it here.
• Limited storage ceiling: 64 GB maximum is restrictive for long trips or dense city driving. Many competitors now support 128–256 GB.
• No companion app: There’s no Wi-Fi or Bluetooth pipeline for quick clip transfer. You’ll be removing the card or plugging the camera into a computer to pull footage.
• Basic parking mode: It works, but lacks buffered capture and fine-grained scheduling.

Who it suits best

• Budget-minded drivers who want front + cabin coverage without extras.
• Rideshare and delivery drivers who value an interior view for accountability, mostly during daytime and well-lit nights.
• Anyone who doesn’t mind a button-driven interface and can spend 15 minutes dialing in settings.

Who should look elsewhere:
- Users who want hands-off setup, phone-based control, and cloud backup.
- Drivers who need high-confidence plate capture at night or 4K front resolution.
- Those requiring GPS, speed logging, or larger storage support.

Reliability and heat

Mounted behind the mirror in late-summer sun, the unit got warm but not alarming. The screen timeout helps keep temps down. Suction stayed put over days of heat cycles. File integrity remained intact; no corrupted clips showed up in my transfers. As with any dash cam, a quality microSD card and periodic formatting are key to long-term stability.

The bottom line

The Sherum dash cam delivers the basics of dual-channel recording in a compact, affordable package: 1080p front, a useful cabin view, serviceable night vision, and dependable loop recording with G-sensor locks. It’s competent where it counts—quietly capturing your drive—once you get past the learning curve. The trade-offs are equally clear: a fiddly button interface, modest storage support, no GPS or app, and a parking mode that benefits from a separate hardwire kit.

Recommendation: A cautious yes for value-focused buyers who specifically want front-and-cabin coverage and don’t mind a spartan interface. If you prioritize ease of use, app connectivity, GPS metadata, or higher-resolution night performance, there are better (though pricier) options. If your budget is tight and your expectations are grounded—reliable two-channel recording, decent night shots, and set-and-forget operation after initial setup—the Sherum is worth considering.
