TomTop offers the Owsoo 4-Channel 1080n DVR Security System with Four Cameras for $56.99 with free shipping. That's tied with our mention from two weeks ago and the lowest price we could find by $62. The system features a DVR with 1080x960 (1080n) video recording, four water-resistant 720p infrared cameras, night vision up to 98 feet, motion detection, Ethernet, email alerts, USB, and remote viewing via the NVSIP mobile app.

Note: This system requires a hard drive to function (not included). The countdown timer on the product page does not reflect an actual expiration time and resets daily.

Update: The price has increased to $58.99.
