Deal Parade via eBay offers the refurbished Netgear Arlo Video Server with Two Wireless IP Cameras for $139.99. With free shipping, that's $10 under our Black Friday mention of a new unit and $49 less than the best deal for a new unit today. It features motion-activation, automatic recording and alerts, night vision, and support for up to five cameras. Note: A 90-day warranty is included, but it's unclear who backs it.
