Vantrue E1 Pro vs VIOFO WM1
Two compact, front-only parking cameras that both rely on a supercapacitor to survive a hot parked car — pay more for the Vantrue E1 Pro's true 4K and plate clarity, or save with the VIOFO WM1's capable 2K at around $100.

How they differ in real use
These two are close cousins: both are small, discreet, single-lens cameras built around a supercapacitor rather than a battery, which is exactly what you want for a camera that bakes in a parked car all afternoon. The decision between them is mostly about image quality versus price. The Vantrue E1 Pro records true 4K on a current Sony STARVIS 2 (IMX678) sensor and adds PlatePix processing tuned to keep license plates legible — the detail that actually matters when you're trying to identify whoever clipped your bumper and drove off. The VIOFO WM1 records 2K on an older Sony STARVIS (IMX335) sensor; it's sharp and perfectly usable, but it won't resolve a plate across a parking lot the way the E1 Pro can. Both offer buffered parking modes, both need a separate hardwire kit to run parking mode with the engine off, and both are front-only — neither sees a hit from the rear, which is the shared limitation to accept before buying either. Where they diverge again is price and polish: the E1 Pro runs about $150 and is LTE-ready for future connected features, while the WM1 lands near $100 and keeps things simple. For a second car, a partner's car, or a tight budget, the WM1 delivers real parking protection cheaply; for the best chance of a usable plate, the E1 Pro is the sharper tool.
Vantrue E1 Pro
- Supercapacitor withstands extreme heat, so parked recording stays reliable in a hot car
- True 4K on a Sony STARVIS 2 (IMX678) sensor with PlatePix keeps plates legible day and night
- Dollar-coin-sized body mounts discreetly behind the mirror
- 5GHz Wi-Fi, GPS, and an included CPL filter to cut windshield glare
- Front-only — no rear coverage for parking hits from behind
- Parking mode needs a hardwire kit (about $20 extra) or a battery pack
- No built-in cloud backup
VIOFO WM1
- Supercapacitor and three parking modes for around $100 — parking features usually reserved for pricier cameras
- 2K (1440p) Sony STARVIS front lens is sharp for the price
- Compact, discreet body with 5GHz Wi-Fi and built-in GPS
- Voice notifications and loop recording built in
- Front-only, single channel — no rear or cabin coverage
- 2K rather than 4K, on an older STARVIS (not STARVIS 2) sensor
- Parking mode needs the separate HK4 hardwire kit
Which should you buy?
Choose the Vantrue E1 Pro if plate legibility is the point of the camera — its 4K STARVIS 2 sensor and PlatePix processing give you the best shot at reading a plate in a parking-lot hit-and-run, and it's LTE-ready if you later want connected features. Choose the VIOFO WM1 if you want genuine parking protection at the lowest price: its supercapacitor and buffered parking modes cover the fundamentals for around $100, which is remarkable for the feature set. Buy the E1 Pro for clarity, the WM1 for value — and remember both are front-only, so add a second camera if rear parking coverage matters to you.
Choose the Vantrue E1 Pro if
- Drivers who want the smallest, most discreet parking camera
- Owners of hot-climate cars who need supercapacitor reliability
- Anyone wanting 4K plate capture in a mini body
Skip it if
- Drivers who need rear parking coverage
- Those who want parking mode with no extra purchase
Choose the VIOFO WM1 if
- Budget buyers who still want real parking-mode protection
- Drivers who want a small, simple front camera
- A first dash cam with supercapacitor reliability
Skip it if
- Drivers who need rear or cabin coverage
- Anyone who wants 4K footage
Common questions
Do either of these cover the rear of the car while parked?
No — both the Vantrue E1 Pro and the VIOFO WM1 are single front-facing cameras, so a parking hit from behind won't be recorded by either. That's the main trade-off for their compact size and low price. If rear parking coverage is important, look at a two-channel front-and-rear camera such as the VIOFO A229 Plus instead, and treat these two as front-only options.
Is the E1 Pro's 4K really worth the extra money over the WM1's 2K?
For parking protection specifically, resolution earns its keep when you need to identify a vehicle or read a plate at a distance, and there the E1 Pro's 4K STARVIS 2 sensor and PlatePix processing have a clear edge. If you mainly want a record that something happened and a general description of the other car, the WM1's 2K is enough and saves about $50. The bigger the parking lot and the farther away the action, the more the E1 Pro's extra detail matters.
Do both need a hardwire kit for parking mode?
Yes. Both run parking mode only with constant power, so each needs a hardwire kit connected to the fuse box (the E1 Pro can alternatively use a battery pack). The bundled cigarette-lighter adapter on either camera only supplies power while the engine is running. Budget roughly $20 for the kit on top of the camera's price if you intend to use parking mode.
