Sam's Club offers its members the Night Owl 8-Channel 1080p 1TB DVR Security System with Four Cameras for $249.88 with free shipping. (Non-members pay a $24.98 surcharge.) That's tied with our mention from two weeks ago and the lowest price we could find now by $39 (although most retailers charge $450 or more).

The system features four weather-resistant 1080p infrared cameras with a 100° field of view, night vision up to 100 feet, motion and heat detection, a DVR with 1TB hard drive, integrated 2-hour battery backup, Ethernet, email alerts, and remote viewing via the Night Owl HD mobile app. Deal ends January 31.
