SupercapacitorScreenless

Viofo's floor is the WM1: a screenless wedge with a 5MP Sony STARVIS IMX335 shooting 2560x1440 at 30fps behind an f/1.8 lens quoted at 135 degrees, which is the narrowest front lens in this catalog and quietly one of its better ideas. A narrower lens spreads the same 2560 pixels over less scene, so the WM1 samples about 19 horizontal pixels per degree - higher than several 1440p cameras that cost twice as much and quote 150 or 170 degrees. What ninety dollars does not buy is convenience: 2.4GHz Wi-Fi, no screen, no voice control, a 256GB card ceiling and no rear channel. What it does buy, and this is the part that matters, is a supercapacitor rated -4 to 149 degrees Fahrenheit rather than the lithium cell almost every camera at this price uses. Buffered parking mode works with the Type-C HK4 hardwire kit. This is the camera to put in a second car or hand to a teenager.

Best for

A second car, a teen driver, or anyone who wants a real camera without a real budget.

The description and the pros and cons above are written from published specifications, not from owner reports. Owner sentiment, where we have it, is in its own section below.

What the numbers mean here

The front camera records 2,560 horizontal pixels across a published 135-degree field of view, which is 19 pixels per degree — plate-legible a few lengths ahead. There is no rear channel on this model. How this is calculated, and what it does not tell you.

It runs on a supercapacitor rather than a lithium cell, so there is no battery to swell in a car parked in summer sun — the classic way a windshield-mounted camera dies. The maker publishes an operating range of -4°F to 149°F. Supercapacitors and heat.

Keeps a rolling buffer, so the seconds before an impact are saved as well as the impact itself. It is the most useful parking mode and the hungriest. The hardwire kit is a separate purchase, which is the line item people forget when budgeting. What each parking mode records.

Features

2560x1440 at 30fps, Sony STARVIS IMX335
135-degree f/1.8 lens - the narrowest front field of view here
Supercapacitor, -4 to 149 degrees Fahrenheit
Screenless wedge body with built-in GPS logger
2.4GHz Wi-Fi and app control
Buffered, time-lapse, low-bitrate and motion parking with the HK4 kit

Where it is strong

Supercapacitor power at a price where almost every rival uses a lithium cell that dies in a hot car
The narrow 135-degree lens gives it better pixel density than several more expensive wide-angle 1440p cameras
Screenless and tiny, so it genuinely disappears behind a mirror
Built-in GPS logger, which budget cameras usually make an accessory

Where it gives way

2.4GHz Wi-Fi, and the app is the only way to see footage since there is no screen
256GB card ceiling and no rear channel
Original STARVIS rather than STARVIS 2 - visibly noisier on unlit roads
The narrow lens that helps plate detail also means less peripheral coverage at intersections

What owners say

We have not collected enough owner discussion about the Viofo WM1 to write this section. We only summarise sentiment for cameras whose owners we have actually read, so this is left empty rather than filled in with something plausible. How we compare explains where the sentiment on other pages comes from.
