Newegg offers two Trendnet Day / Night 802.11n Wireless 2-Way Baby Cameras
with free shipping
. At $17.99 each, that beats our March mention (which saw these cameras for $23 each.), is a current best for this quantity by $31, and is the lowest per-unit price we've seen. (Most retailers charge around this price or more for just one
camera.) It features a microphone and speaker, 4x digital zoom, night vision up to 16 feet, sound and motion detection, remote viewing via its free mobile app, song-playing capability, and mounting hardware.
