Who makes it: Logitech
What it costs: $650
Why we like it: Cable and telephone companies think home security is the next big thing in broadband services. Logitech's Alert 750N Indoor Master System with Night Vision and 750e Outdoor Master System were the easiest do-it-yourself systems we tried, with setup taking about 20 minutes. They include a night-vision lens and can automatically record video when motion is detected. Apps for tablets and smartphones let you use the Web to take a gander at what's happening at home in real time.
