OnCue

A SECURITY CAMERA ON THE MAC YOU ALREADY OWN


Point it at a door, a desk, or a room. Set how much motion or sound should set it off, arm it before you leave, and it records while something's happening, to a folder you choose.

What it does

Motion, sound, or both

Each trigger has its own meter and its own threshold, and each can be switched off on its own. Watch the meters move, set the sliders where you want them, and arm it.

The seconds before it starts

OnCue keeps the last few seconds in memory, so every recording begins before whatever set it off. Five seconds by default, up to thirty.

Two cameras at once

Use your Mac's camera and a USB webcam together, each with its own view and its own sensitivity, recording to its own file.

Recordings you can find

Files go to your Movies folder, or any folder you pick, named for the time they start and the camera and microphone they came from. The menu opens the folder at the newest one.

It stays awake

While it's armed, OnCue keeps your Mac from going to sleep, warns you when closing the lid would stop it, and tells you afterwards if your Mac slept anyway.

Nothing leaves your Mac

No account, no cloud, no network. Recordings stay in the folder you chose until you move them. Point it at a synced folder and they sync; that's up to you.
