If you're using iSmartAlarm as part of a larger setup, you'll be able to connect it with the existing CubeOne hub accessory, and use those motion and sound sensors to trigger the alarm. You'll also be able to monitor your feed alongside your other iSmartAlarm devices, including the new Smart Switches seen here.
iSmartAlarm tells us that they'll also be offering options for cloud storage, though they're still working out the pricing. A USB jack in the back will allow for local storage of video clips, but that functionality isn't ready yet either. In fact, as of right now, you can only use the camera for live monitoring -- you can't record with it yet, or set it to record a clip automatically when the alarm goes off.
The iCamera Keep is available online at the iSmartAlarm website for $150 (converted roughly, that's about £100 in the UK, or AU$190 in Australia). You can also find it at Walmart, Fry's, Amazon, and the Apple Store. Be sure to read our full review to help you decide if it's worth your money.
