Cameras store video recordings in several ways. Many offer free cloud storage for a limited number of days (typically seven) before it is overwritten or deleted, while others are strictly subscription-based. If you require more than a week's worth of video storage, you can subscribe to a 30-day plan to avoid worrying about losing important footage before you get to review and download it. If you're concerned about privacy and would rather not store your video in the cloud, look for a camera that offers a local storage option via a microSD card slot. A few cameras let you save video recordings to a portable USB or NAS drive, but these devices are rare. And if you want the ability to go back and see everything, look for a camera that offers a CVR (Continuous Video Recording) plan. With this option, the camera records continuously and stores up to 30 days of 24/7 video in the cloud.
