Currently Vilecam is privet but possibly public in 6 months
Here are the two camera's I use that work well:
(The Sony will send and receive audio, the Linksys has only a Mic no speaker)
Sony SNC-M1- $160.00 - $87.00
Affordable range of all-in-one network cameras that incorporate built-in web servers, network interfaces, and built-in microphones to their compact and stylish bodies. With a single camera, both video and audio monitoring can be achieved over a network to meet the demands of a wide range of applications. The cameras utilize the MPEG-4 compression format, which achieves a high compression ratio, providing smooth video and audio streaming over network environments - including those with limited bandwidth.
