From the developer:
OnCue turns your Mac into a motion and/or sound activated surveillance system. With the free OnCue iOS app, now you can view your camera's feed from anywhere you have an internet connection.
The images your camera sees are encrypted and securely transmitted (TLS with 2-way authentication) over the internet to your iOS device.
