70mai 4K M800
The 70mai 4K M800 is a compact, screen-less dual dash camera with 4K HDR front recording and 1080p HDR rear recording, delivering excellent daytime and ok nighttime image quality.
Build quality is good, the camera has reliable voice prompts, and optional 4G remote monitoring and cloud features.
However, the camera has some drawbacks. It relies on built-in 128GB eMMC storage (no removable SD card), making footage retrieval slow and preventing easy storage replacement if memory issues occur. Also it has slow Wi-Fi 4 speeds, only 1080p rear resolution, and the use of an internal battery instead of a capacitor.
Overall in this price range there are better options without the drawbacks listed above.

70mai M800 Dash Cam ReviewThe 70mai M800 is a compact, display-free 4K dash cam that prioritises a discreet, "set and forget" installation. By moving away from a traditional screen-based design, 70mai has created a unit that is remarkably unobtrusive while maintaining high-end optical specifications. I have been playing with this unit since August 2025 International release but keep in mind what I have found may have been updated since then. Discreet Design and Ease of…
