Dropcam recently announced a feature that lets its cameras detect people moving in your home. The cloud-powered software then sends an alert to your smartphone app or email account. The company also has a subscription product that lets you record up to seven days' worth of video from your Dropcam. You can go back at any time and review the footage and save clips.
