Or, with a Mac and the built-in iSight camera, you’ve got a free security system that snaps a photo of anyone who trips up the motion sensor app. It’s the easy and free way to guard your home, Mac, or office.
The Invisible Snitch
iSentry is probably the least expensive motion sensor you can add to a MacBook, an iMac, or any Mac connected to a decent USB video camera.
Use the built-in controls to have iSentry activate at a certain time, enable sound alerts when the motion sensor camera is tripped, or have it send you an email notification.
iSentry can take photos or video clips of what it detects and upload them to an online site.
App controls are rather simple, though. A slider bar controls sensitivity of detection (which may not catch a pet walking by, but would capture a photo of someone walking by the camera).
Photo recording or video recording is a toggle choice (one or the other). The rest of the settings are self explanatory.
Simple, sweet, effective.
Once you’ve walked through the setup, just point your Mac or the camera where you need it most, and click the Start button in iSentry.
iSentry monitors what the camera sees. If motion crosses the camera’s vision, it’s detected by iSentry which captures an image or video of the moment, and issues email or an alarm.
Why is iSentry free?
That’s always a question that bothers me about new apps. Why invest time and effort into an app if it’s not likely to be around and updated after a few months or years.
iSentry doesn’t work with every webcam model, either, but does well with the built-in iSight camera on my desktop iMac.
