Get two Canary All-in-One Home Security Devices for $349.99 at Verizon Wireless. Plus, the shipping is free. A single unit drops from $199.99 to $179.99, which was the same discount we found everywhere else, so getting two for $349.99 cuts $25 off the price of one and makes this the best deal for multiple units. The Canary combines a wide-angle, motion detecting HD camera with a 90+dB alarm and temperature, humidity and air quality sensors. It has built-in WiFi for sending video feeds and live alerts to your phone (via a free app) when activity has been detected and can be programmed to ignore false alarms such as pets or to contact emergency services in the event of a break-in or fire. Sales tax is charged in most states.
