 Turn your old smartphone into a new security camera.

Haven is one of the best apps for this (it was developed by Edward Snowden's team by the way!). To use, you should: Download the app from Google Play. Configure sensor sensitivity (as well as sensitivity for camera, accelerometer and microphone). Set up SMS notifications and select a camera for monitoring. Set up remote access to the phone through the Orbot browser for Tor: install the application on Google Play and select “Haven” in the “VPN Mode” section.
