Pelsee S1 Pro 4K Dash Cam

Updated October 22, 2026. Based on the Amazon listing and owner reviews, not a hands-on test.

Quick verdict: The Pelsee S1 Pro suits drivers who want sharp 4K recording on both the front and rear cameras, plus GPS, Wi-Fi 6, and voice control, without buying a memory card separately. Its main strength is the native 3840x2160 resolution on both channels, which the listing says is not upscaled. The main catch is that 24-hour parking surveillance needs a hardwire kit that is not in the box, and the review base is still fairly modest.

Who should buy it (and who should skip it)

Good fit if you

• Want true 4K footage from the rear camera too, not just the front, so plates behind you are easier to read.
• Drive for rideshare, commute daily, or take long road trips and want GPS speed and location stamped on every clip.
• Prefer pulling clips to your phone over Wi-Fi instead of removing the microSD card.
• Like hands-free controls, since voice commands can lock footage or switch camera views.
• Want a complete kit, with a 128GB card, rear camera cable, and install tool included.

Skip it if you

• Need parking mode right out of the box with no extra wiring. The listing states a hardwire kit is required.
• Want a tiny, hidden camera. A 3.39-inch screen means the front unit is more visible than screenless designs.
• Prefer a brand with a long track record and thousands of owner reviews to draw on.

Key specs at a glance

What it does well

Native 4K on both cameras

Many front and rear kits pair a 4K front camera with a 1080p or 2K rear camera. The S1 Pro listing says both channels record at 3840x2160 at 30fps simultaneously, and it stresses that the footage is not interpolated or upscaled. That matters most for the rear view, where reading the plate of a car that tails or hits you is the whole point.

The front lens covers 170 degrees and the rear covers 150 degrees. Based on the specs, that is wide enough to capture adjacent lanes and cars pulling out from the side, which is where many disputes start.

HDR and low-light design

The listing pairs 8MP HDR processing with an f/1.5 aperture lens, a GalaxyCore low-light CMOS sensor, and multi-frame noise reduction. In practical terms, HDR is meant to keep bright headlights and dark shadows readable in the same frame, which is a common weak spot for budget dash cams at night or in tunnels.

The f/1.5 aperture is wide for a dash cam, so it lets in more light. Pelsee describes the night output as full-color rather than black and white.

GPS and Wi-Fi 6 for evidence and transfers

The built-in GPS module writes speed, location, and time onto recordings. If you ever need to show an insurer where and how fast you were driving, that data is useful context.

Dual-band Wi-Fi 6 with 5.8GHz support is a real convenience upgrade. 4K files are large, and the listing claims transfer speeds up to 30MB/s, which helps when you are saving a clip on the roadside. The app also offers live preview, playback, sharing, and over-the-air firmware updates.

Voice control and a usable screen

Voice commands cover switching between front and rear views, turning the screen and audio on or off, taking snapshots, and locking critical footage. Locking a clip by voice right after a close call is a practical safety feature, since you do not need to reach for a button while driving.

The 3.39-inch IPS screen is large enough for instant playback, so you can confirm aim and check a clip without opening your phone.

Complete kit and loop recording

The included 128GB microSD card is a notable plus. Pelsee says it holds up to 12 hours of continuous dual 4K footage before loop recording starts replacing the oldest regular clips. Locked collision clips go to a protected folder that loop recording does not overwrite. Storage expands to 1TB if you want a longer buffer.

The listing also mentions thermal protection for extreme heat and cold, which is relevant for cars parked in summer sun.

Common complaints and limitations

Parking mode is not plug and play

The 24-hour protection features, including time-lapse recording and impact detection while parked, require a hardwire kit. The listing names the kit (ASIN B0C7QY4KB9), and it is not part of the included components. Budget for it if parking surveillance is a priority, and plan for a fuse-box install or professional help.

A modest review history

The product has a relatively modest number of ratings so far. Feedback is mostly positive, but long-term questions such as how the mount, card, and battery hold up after a year or two of summer heat are not well documented yet. Treat it as a newer model.

Spec-related trade-offs

• 30fps only. 4K at 30fps is standard, but fast-moving plates can still blur. Higher frame rates are not listed.
• Suction mount. Suction cups can loosen with temperature swings, and they are bulkier than adhesive mounts. Expect to check it now and then.
• Storage fills fast. Dual 4K uses a lot of space. Twelve hours on 128GB is fine for most commutes, but heavy drivers may want a bigger card.
• Visible unit. The screen makes the camera easier to use but harder to hide behind the mirror.
• Little written feedback to go on. The reviews we could sample had no written comments, so recurring owner complaints are hard to pin down. Read the newest low-star reviews on Amazon before buying.

Setup and everyday use

1. Format the card first. Format the included microSD card in the camera before your first drive. If you upgrade later, use a high-endurance card rated for dash cam use, since constant writes wear out standard cards.
2. Mount behind the mirror. Clean the glass with alcohol, then mount the front unit high and centered so it does not block your view. Check the live preview in the app to level the horizon.
3. Route the rear cable along the trim. Use the included install tool to tuck the rear camera cable under the headliner and down the pillar. Avoid running it across airbag panels on the A-pillar.
4. Turn on GPS and set the time. Confirm the GPS stamp and date are correct so your footage is usable as evidence.
5. Tune the G-sensor. If rough roads keep locking clips and filling the protected folder, lower the sensitivity.
6. Update firmware. Check the app for over-the-air updates after setup and every few months.
7. Back up important clips. Save locked clips to your phone over Wi-Fi soon after an incident instead of relying on the card alone.

How it compares

Against the 70mai A810 Lite 4K Dash Cam, the trade-off is mostly brand familiarity versus features. 70mai is a well-known dash cam name, while the Pelsee S1 Pro leans on a feature-heavy package: native 4K rear recording, Wi-Fi 6, voice control, a large screen, and an included 128GB card. Compare rear resolution and what comes in the box before you decide.

Against the generic Front 4K + Rear 4K Dual Dash Cam, both promise 4K on both ends. The Pelsee listing is more detailed about its sensor, aperture, GPS, and storage, which makes it easier to judge what you are getting.

Frequently asked questions

Does the Pelsee S1 Pro record true 4K on the rear camera?

Yes, according to the listing. Both the front and rear cameras record at 3840x2160 at 30fps at the same time, and Pelsee states the footage is native 8MP, not upscaled.

Does parking mode work without a hardwire kit?

No. The listing says the 24-hour parking surveillance, including time-lapse recording and collision lock while parked, requires a hardwire kit (ASIN B0C7QY4KB9). It is not listed among the included components.

How much footage does the included 128GB card hold?

Pelsee says about 12 hours of continuous dual 4K footage. When it fills, loop recording overwrites the oldest regular clips, while locked collision clips are kept in a protected folder. The camera supports cards up to 1TB.

Can I download clips to my phone?

Yes. The camera has dual-band Wi-Fi 6 with 2.4GHz and 5.8GHz support and an app for live preview, playback, download, sharing, and firmware updates. The listing claims transfer speeds up to 30MB/s.

What can the voice commands do?

The listed commands include switching between front and rear views, turning the screen and audio on or off, taking snapshots, and locking footage. The camera gives audio feedback to confirm each command.

Will it fit my vehicle?

The listing names cars, SUVs, sedans, trucks, vans, minivans, RVs, and rideshare or taxi vehicles. It uses a windshield suction mount and a car charger adapter with a USB cable. Check that the rear cable can reach your rear window before buying.

Bottom line

The Pelsee S1 Pro packs a lot into one box: native 4K on both cameras, an f/1.5 low-light lens, built-in GPS, fast Wi-Fi 6 transfers, voice control, and a 128GB card ready to go. It makes the most sense for drivers who want clear rear footage and easy clip sharing. Plan on a separate hardwire kit if you want parking protection, and keep in mind that its owner history is still building. If those trade-offs work for you, check the current price and what is included on Amazon.
