Our take on the Mini Hidden Camera DIY Module, HD 4K Wireless Cameras, Small WiFi Nanny Cam, Portable Tiny Security Camera for Home Indoor & Outdoor

The Ctetma Mini Hidden Camera is a tiny DIY WiFi module that records 4K video and streams live to a phone app over 2.4GHz WiFi. It supports microSD cards up to 256GB for local storage and sends motion alerts. It suits people who want a discreet camera for home monitoring, but it lacks a built-in battery, night vision, and audio, and the 4K claim is questionable for a sensor this small.
