Sam's Club offers its members the Ezviz 16-Channel 1080p Security System for $429 plus around $5 for shipping. (Non-members pay $42.90 extra, or you can get a 1-year membership for $45.) That's $10 under our December mention and the lowest price we could find by $110. It includes 12 1080p cameras with 100-foot night vision range, 16 channels, and a 2TB hard drive. Deal ends March 14.
