The base unit itself can detect motion and sound, and when its smart sensors are triggered it can record in 1080 HD video.

It's also compatible with a number of other smarthome devices, which can be configured so that even when you are away, indoor and outdoor lighting can be programmed to simulate someone at home. When an event is triggered, an alert can be sent via text to your phone or other device, along with a video and/or audio clip of it.
