NOYB

NOYB is an app that monitors and reports any microphone and camera activity to help users figure out if someone’s spying on them. Additionally, Micro Snitch logs all usage automatically, meaning that users can go back and check its records even if they’re not in front of the computer when they suspect the spying might have occurred. Micro Snitch is available directly from Objective Development and via the Mac App Store for $3.99.
