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?
