Axis Communications 211A Network Camera with two-way audio
We'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).
