Amazon offers the Netgear Arlo Q 1080p Power Over Ethernet Security Camera for $199.95 with free shipping. (Newegg and Home Depot charge the same.) That's the lowest price we could find by $48.

What makes this unique over the other Arlo cameras is that it is powered over an Ethernet connection, meaning you have 24/7 recording of 1080p video via the built-in SD card slot, not just short clips triggered by alerts. (Triggered alerts are still uploaded to the cloud for seven days.)
