Dash Cams: Five Listings Compared by Resolution, Channels and Mounting
As an Amazon Associate we earn from qualifying purchases.
A dash cam records the road ahead, and some models also record behind the car or inside the cabin. The listings in this group range from a single 4K front camera to a four-channel 360-degree unit, and they differ in resolution, mounting style, connectivity and the memory card included. Resolution is the number most sellers lead with, but the number of channels and the storage plan matter as much for a complete record. This guide reads five listings by the details each one states.
Quick answer
Choose the coverage first. A single front camera records one direction, a front and rear unit records two, and a four-channel unit covers more of the car. Then check the resolution. The listings here state 1080p, 1440p, 2K and 4K. Finally, check the memory card and the storage, since a card fills quickly with high resolution video, and the listings give different card sizes.
How we chose
Each entry uses the product details saved for the listing: video resolution, connectivity, mounting type, screen size, compatible devices, included memory card and color. The guide reports these as the listing states them. It does not describe how clear the footage is at night, how the camera holds up in heat, or whether the recordings would be accepted in any dispute.
What we could not verify
Night vision and image clarity are not tested here. Titles that name a sensor, such as STARVIS 2 or starlight night vision, are the sellers’ claims. Some listings give resolution as upscaled, and the guide notes where that appears. Legal use of recordings varies by place, and this guide does not give legal advice.
The five listings
ROVE R2-4K: dual front and rear dash cam, STARVIS 2 sensor, 128 GB card included
The ROVE R2-4K is a dual dash cam covering the front and rear. The video resolution is listed as 1080p, 2160p upscaled and 1440p native.

A comparison by channels and resolution
| Dash cam | Channels | Resolution as listed | Screen | Card included |
|---|---|---|---|---|
| ROVE R2-4K | 2 (front and rear) | 1080p, 2160p (upscaled), 1440p | 3 in | 128 GB (title) |
| galphi | 1 (front) | 2160p | Not stated | 32 GB |
| IIWEY N6 | 4 | 1440p, 2K plus three 1080p | 3.18 in | 128 GB (title) |
| Aputeta | 2 (front and rear) | 4K front and rear | 3 in | 128 GB (title) |
| REDTIGER F7NP | 2 (front and rear) | 1080p, 2160p | 3.16 in | 128 GB |
Channels and resolution are the two columns to compare first. Two-channel units record the front and rear, and the four-channel IIWEY covers more of the car.
Coverage and channels
A front camera records the road. A rear camera records what is behind the car, which helps if the car is hit from behind. A cabin camera records inside the car, which some drivers use for rideshare trips. Choose the coverage you need before comparing resolution.
Storage and the memory card
High resolution video fills a card faster, so a 4K two-channel unit needs more storage than a 1080p single-channel unit. Most listings here include a 128 GB card in their titles, and the galphi listing includes 32 GB. Confirm the card size and the maximum card support for the unit.
Mounting and power
A windshield mount holds the camera behind the mirror, and an adhesive mount sticks to the glass. Check the cable routing and the power source. The listings name USB and Wi-Fi connectivity, and the power cable runs from the cigarette lighter or the fuse box.
Checks to make before you order
Decide which directions you need to record: front, rear or cabin.
Check the card size and the maximum storage the unit supports on the product page.
Confirm the mounting type fits your windshield and the cable route.
Which dash cam suits which driver
For a front-only record on a budget, the galphi single camera is the simple choice. For a front and rear record, the ROVE R2-4K and REDTIGER F7NP are the closest matches. For a four-channel record that includes the cabin, the IIWEY N6 is the one to compare. For the highest listed resolution in a two-channel unit, the Aputeta is the one to look at.
Frequently asked questions
Is 4K better than 1080p for a dash cam?
4K gives more detail, but it fills the memory card faster. Choose by how much detail you need and how much storage you have.
Do I need a rear camera?
A rear camera records behind the car. It is a choice based on the coverage you need.
Can dash cam footage be used in a claim?
This guide does not give legal advice. Check the rules where you drive before relying on footage.
