Yallstore via eBay continues to offer this 720p Pan and Tilt WiFi Security Camera for $19.99 with free shipping. That's tied with our mention from a week ago as the lowest price we've seen for any pan/tilt security camera. (Outside of other eBay sellers, it's the best deal now by $3.) It features 355° pan and 90° tilt, micro SD card slot, 802.11n wireless, and 2-way audio.
