Great app, great price!
"Q: How is OverSight different than other tools (such as MicroSnitch)?
A: OverSight is unique in a variety of ways:
• OverSight is 100% free (no demo mode, limited functionality, etc).
• OverSight is able to identify the process that is accessing the webcam. When your webcam's LED light randomly comes on, you'd want to know what process triggered that, right?
• OverSight provides the means to either 'allow' or 'block' a process that is accessing the webcam.
• OverSight can detect secondary 'consumer' processes that may be piggy-backing off a legitimate webcam session in order to stealthily record the user without detection. (See: "Getting Duped: Piggybacking on Webcam Streams for Surreptitious Recordings" for details on this novel attack)."
