Walmart offers the Arlo Pro 2-Camera 720p Security System bundled with an Arlo Outdoor Mount in White for $239 with free shipping. That's tied with our mention from a week ago and $58 under the lowest price we could find for these items purchased separately elsewhere. The system includes two cameras that feature:

1280x720 (720p) video capture resolution

130° viewing angle

night vision up to 25 feet via 850 infrared LEDs

motion detection

2-way audio

rechargeable battery

The base station features a 100-decibel siren, support for live monitoring, Ethernet, and USB.
