This is a tiny HD camera that stores video and still photos on a micro-SD card (not included). It is really small and inconspicuous, measuring about 7/8 inches squared. It can be mounted a number of ways, including using a built-in magnetic base, a magnetic adjustable base, or by double-stick tape. It charges the built-in battery using a USB cable (included).
In the motion detection mode, it will standby and only record when it senses motion. It can record about an hour on a fully-charged battery, and can also be powered using a USB power bank or charger.
