The Miofive S1 already established itself as a capable budget dash cam, delivering genuinely impressive 4K footage at a price point accessible to owner-operators and small fleets. In our previous Professional Van review of the S1, the core verdict was clear: strong video performance slightly undermined by intrusive alerts and minor usability quirks.
Pros
+ Excellent 4K front camera quality
+ Strong value for a dual-camera system
+ Straightforward installation and setup
Cons
– Rear camera redundant in panel vans
– Overly intrusive voice alerts
– Mount quality feels budget-grade
The Miofive S1 Pro builds directly on that device by adding a secondary 2K rear camera. While this sounds like a straightforward upgrade, its real-world usefulness depends heavily on the type of vehicle you drive.
At a hardware level, very little has changed. The primary camera unit is identical to the Miofive S1, retaining the same compact casing, three-inch display, built-in GPS and Wi-Fi connectivity. Video quality, menu behaviour and the camera’s well-known voice notifications remain consistent with the standard model.
In effect, the S1 Pro is best understood not as a new dash cam, but as a variant of an already familiar one.
Installation: Where the Pro model becomes divisive
Fitting the main camera is refreshingly simple. The adhesive windscreen mount and long USB-C power cable allow for a quick, tidy installation, and the camera is compact enough to sit discreetly behind the mirror without significantly affecting visibility.
The secondary camera is where commercial vehicle realities begin to intrude.
The average dual-camera dash cam is designed for passenger cars, where rear glazing is universal (well, at least until the Polestar 4
arrived…) and cable routing, while sometimes awkward, is rarely problematic. Most working vans, however, feature solid steel rear doors and full-height bulkheads, leaving a rear-facing camera with little to capture. Even in glazed vans, longer body lengths and more complex trim layouts make cable routing more involved than in typical passenger vehicles.
For a significant portion of panel van operators, the S1 Pro’s headline feature may therefore offer limited practical benefit.
Video performance: Still defined by the front camera
None of this detracts from the S1 platform’s strongest attribute. As noted in our original S1 review, the forward-facing camera produces crisp, well-exposed 4K footage that performs well above expectations for a budget unit. Registration plates, lane markings and surrounding traffic remain clear enough for evidential use in typical driving conditions.
Regardless of the chosen resolution, recording is fixed at 30 frames per second. While higher frame rates can improve motion smoothness, clarity and exposure remain the priorities for incident documentation, and here the Miofive hardware continues to deliver.
Low-light performance is similarly respectable for the price, with well-controlled noise levels and plenty of scene detail.
Everyday use: Familiar strengths and irritations
Because the main unit is unchanged, so too are its behavioural quirks. The camera’s voice prompts and driver alerts remain overly enthusiastic, something we previously identified as a weakness of the S1. In commercial vehicles, where drivers may spend entire working days behind the wheel, repeated audio notifications can quickly become tiresome.
Most operators will likely disable these functions, leaving the camera to perform its primary task: quietly recording footage.
Who should consider the Miofive S1 Pro?
The S1 Pro makes the most sense in vehicles where a rear camera can function as intended. Pickups, SUVs, crew vans and Kombi-style passenger derivatives are obvious fits, allowing the secondary camera to capture genuinely useful rearward recordings.
For conventional steel-doored panel vans, the equation is less convincing. The additional camera increases installation complexity and cost while often providing minimal operational advantage. In many cases, the simpler Miofive S1 remains the more pragmatic choice.
Miofive S1 Pro DashCam: Verdict
The Miofive S1 Pro inherits the same strong fundamentals that made the Miofive S1 an appealing budget dash cam, particularly its impressive 4K front camera performance. Its limitation lies not in image quality but in applicability.
For drivers of pickups and glazed vehicles, the Pro variant is an easy upgrade to justify, especially at a mere £15 premium over the single-camera model. For many van operators, especially those running standard panel vans, the rear camera may represent a feature you pay for but rarely benefit from.
