About this app

rimca turns your unused smartphone into a home monitoring and security camera.

Simply install the app on an old smartphone and place it wherever you need it. With real-time video streaming, you can check what is happening at home anytime from a web browser on your computer or smartphone, even while you are away.

Use rimca to keep an eye on pets, children, or elderly family members, or as a security camera for your entrance, store, office, and more.
