Amazon offers the refurbished Netgear Arlo Pro Security System with Five 720p Cameras for $514 with free shipping. That's $55 under our May mention and the best price we've seen. (It's also $283 under the lowest price we could find for it new.) The system includes five cameras and a base station. Each weatherproof wireless camera features a:
  • 1280x720 (720p) video resolution
  • 130° wide-angle lens and night vision up to 25 feet
  • motion detection and 2-way audio
  • rechargeable battery and magnetic mount
Note: A 90-day warranty applies, but it's unclear who covers it.
