Miofive S1 Ultra
$15 under your budget
The cheapest true front-and-rear pick across 11 sources — 4K front, 4K rear, Wi-Fi, GPS, 24h parking mode, and a 64GB card in the box.
Fit ledger — need → measured evidence
■ The catch — co-equal billing, always
Nobody names its sensor. Every other 4K pick in this comparison is spec'd to a Sony STARVIS 2 (IMX678); the S1 Ultra is sold only as "Super Night Vision" — and this is the category where 2K gets upscaled and marketed as 4K. Its 112° rear lens is also the narrowest here.

Traps — this verdict avoids
Why the Miofive S1 Ultra is right for you
It avoids every trap below — and for anyone, under $150, it is the pick because it delivers:
Channel-count bait
Front-only, front+rear (2CH) and front+rear+cabin (3-4CH) are different SKUs sold under near-identical names $60-200 apart. The Nextbase iQ 4K is a front + cabin unit whose rear-window camera is a separate ~$149 accessory; the Viofo A119M Pro, Garmin Mini 3, Garmin X310, Vantrue E1 Pro and Nextbase Piqo are all front-only. Every price here names its configuration.
The card is not in the box
Only 5 of these 15 picks include a microSD card. A consumer-grade card fails within months of continuous loop recording — and a silently dead card means no footage on the day you need it. Budget $20-45 for a high-endurance 128-256GB card; 4K at 60fps eats roughly 500MB per minute.
Parking mode is sold separately
Parking mode needs a hardwire kit ($15-30, usually not included) run to the fuse box — without it most cams only record while the engine runs, and a hardwired cam does draw down the car battery. Buffered recording (which keeps the seconds before an impact) is materially better than motion-detect or time-lapse.
