3D Surveillance Cameras - Low Cost?

For years, 3D cameras have been on the fringe of the surveillance industry with a handful of research projects / defense contractor offerings popping up from time to time. Probably, the only commercial offerings I've seen have been within people counting and those have still been $5,000+ Note: You might recall DVTel's bizarre 3D showcase in 2010 that never came to fruition. However, a low cost 3D sensor from Primasense http://www.primesense.com seems to be gaining a lot of attention, though not directly in the security industry. However, Primasense is used in Kinect, which was featured in Avigilon's recent 3D VMS demo What I am curious about is using these types of 3d sensors in surveillance cameras. They could help with analytics in smaller areas - like people counting or potentially intrusion or motion detection. Anyone know of anyone working on this or have any thoughts on this?

It's 2013. If it's not got a standards-based interface it's broken. 3d, 4d, 7d, xray, thermal, whatever. (not to pick on 3D solutions, I'm just pointing out the tower of babel in the security camera world while the world around us moves through the 21st century...)

Oh boy!

Many people have problems viewing 3D movies in theaters and 3D on Home Theater Systems. Those 3D media are typically produced under carefully controlled conditions and enhanced post-production before the end user even sees it. I can't imagine this offering more than limited benefits for Video Surveillance purposes but I can foresee huge negatives, like eyestrain, headaches, vertigo, etc. on the part of the poor souls that have to view the video for long periods.
