- **价格:** £258.3 [^1]
- **概述:** This 70mai T800 is a 3-channel dash cam with dual front and rear recording at 3840x2160 (4K) plus a 1920x1080 interior camera. It supports AI Motion Detection and 4G connectivity (with a required 4G hardwire kit sold separately), and it uses buffered emergency recording to capture footage before and after an incident. It's powered for parking coverage with a supercapacitor.
- **最适合:** It's designed for car-to-car swapping in a practical way because the dash cam uses supercapacitor-based power and supports 24H parking surveillance and 4G remote features, but it still requires installing the needed hardwire kit for parking/4G so true quick movement between vehicles depends on whether you can reuse the hardwiring setup.
