Eufy's 1080p HD EverCam cameras connect to a Security HomeBase hub with encrypted, local storage. After connecting the hub to your wireless router, the HomeBase stays in constant communication with up to 16 cameras over a low-frequency wireless signal. The base automatically switches to WiFi once it starts recording, and stores the footage on a microSD (it comes with a 16GB card). Most current security systems store your footage on cloud servers, which are typically convenient, but costly. If you prefer remote storage, the EverCam gives you the option for $3 a month, per camera to stash your video in the cloud.
