Watcher can continuously monitor everything happening in front of your screen through your Mac camera and sound an alarm when necessary. For example, if you suspect someone might tamper with your Mac while you are away, you can turn on Watcher to keep watch. For example, you can enable Watcher when you step away briefly; if someone tries to take your Mac, Watcher will sound an alarm. It may also help prevent your Mac from being lost, because Watcher records everything through the camera, displays warnings on the screen, and syncs the recorded images to iCloud.
