Walmart offers the Zmodo 720p Mini WiFi Camera, model no. ZM-SH75D001-WA, for $32.99. (Fry's charges the same, although it's on backorder.) Opt for in-store pickup to avoid the $4.97 shipping fee. That's the lowest price we could find by $7, although we saw it for a buck less in December. It features 16-foot night vision, 720p resolution, two way microphone, and motion-detection alerts via smartphone app.
