Yallstore via eBay continues to offer this 720p Pan and Tilt WiFi Security Camera for $19.99 with free shipping. That's the lowest price we could find by a buck and tied with our mention from last week as the best deal we've seen for any pan/tilt security camera. It features 355° pan and 90° tilt, micro SD card slot, 802.11n wireless, and 2-way audio.
