Axis Communications 211A Network Camera with two-way audio

Axis 211AWe've always wondered why most video security cameras only transmitted audio one way, and so has Axis Communications, which has created the 211A network camera, which transmits 640 x 480 VGA video through Motion JPEG and MPEG-4 simultaneously and allows viewers of the video stream to voice communicate live with the people they are monitoring. The Axis 211A has built-in support for audio and Power over Ethernet (which means you just need one Ethernet cable for power, audio, and video) and will be $900 when it's released in February (yeah, steep).
