About:
OverSight is a lightweight monitor for macOS that detects and alerts users when the built-in microphone or webcam is activated. It provides real-time notifications to identify unauthorized access attempts by malicious software or background processes. This tool enhances privacy by giving users visibility into when their hardware is being used.
Key Features:
  • Real-time monitoring of microphone and webcam access
  • Instant alerts for unauthorized activation
  • Detailed process information for each event
  • Lightweight and low system resource usage
  • Simple, user-friendly interface
Use Cases:
  • Detecting spyware or malware attempting to secretly record audio or video
  • Verifying which applications are accessing microphone/webcam in real-time
  • Enhancing privacy for security-conscious users on macOS
Alternatives:
  • Little Snitch – Network firewall that can detect outbound connections from apps, but not specifically hardware access
  • Security Camera Software – Monitors external cameras, not built-in hardware
