Three current dash cams to compare.
VIOFO A329S 3CH

Vantrue N4 Pro S
Recording: 4K front + 2.5K rear + 1080p inside.
Good for: drivers who want three views and a rear camera with an IP67 water-and-dust rating.

70mai T800
Recording: 4K front + 4K rear + 1080p inside.
Good for: drivers who want 4K recording in both road views, plus an inside camera.

Your quick buying checklist
- Choose your views: front, rear and/or inside.
- Check the model: read the full name and bundle contents.
- Watch the footage: compare day and night clips.
- Add the extras: memory card, parking power and fitting.
- Check clip access: can you save a recording easily?
Make the setup comparable. Put the camera configuration, memory card, rear cable, power accessory and fitting requirements on one checklist. A base listing may leave out items included in another bundle. Compare the total arrangement you plan to use, rather than assuming every listing with the same main model name includes the same kit.
Choose footage that answers a question. Check whether a review identifies the exact model, recording mode and conditions. Front, rear and cabin recordings demonstrate different views. Clear daylight footage is different evidence from moving traffic at night or strong windshield reflections. Use the examples to assess the question they actually show rather than treating one attractive still image as proof of every recording situation.
Plan clip retrieval. Read how the exact camera saves an incident and how you would export it. Local phone access, removable storage and a connected remote service have different requirements. A listing that mentions Wi-Fi does not by itself prove internet access from another location. Confirm the supported connection and any account or service costs before relying on remote features.
Check the parked setup separately. Ordinary recording while driving and recording with the engine off are different uses. Read the supported power arrangement, settings and battery-protection requirements in the current instructions. Include the right hardware and installation in the cost. A review of the camera alone does not establish that the same parking arrangement is suitable for every car.
Record unresolved requirements. If a manual does not answer your vehicle or phone compatibility question, mark it as unconfirmed and ask the manufacturer or an appropriate installer. This avoids turning an assumption into a buying decision. Keep the exact model, regional listing and fitting details available when asking for help.

Sources and how we made this guide
The source of a statement matters. A manufacturer specification describes a documented feature or rating. A manufacturer demonstration is that company’s example. A third-party review belongs to its creator and the conditions they used. Auto Gear Pilot links those sources to help organize your research; a linked video is not a new test performed by this site.
Read the shorter model comparison for a package-focused shortlist, and browse dash cam articles for narrower questions. The Garmin Dash Cam Live article covers a different connected-camera example, while the Garmin app guide helps distinguish pairing, local video access and supported remote features.
If a source link has moved, report the article URL and the label you clicked through our contact page. If two specifications conflict, include the exact model suffix and current primary source. Firmware, region or package differences should be checked before treating similarly named products as identical.
