Take a look at Cognitec FaceVACS-VideoScan and Artec ID Broadway 3D.
The former we have performed some extensive tests regarding facial recognition. The results showed a satisfactory facial recognition of approximately 60%. That is, in 6 out of 10 attempts subjects of interest were recognized. It is important here to mention that many factors can influence the facial recognition rate, such as lighting conditions, subjects that do not look at the camera straight on, amongst others. With regard to assistance, it is worth mentioning here that Cognitec staff members were very helpful by providing us with tips about how to tune up our configuration.
In its turn, we have not evaluated the latter, but we have seen it in action. It looked very impressive, specially when (unsuccessfully) trying to fool the system, for instance, by holding up a picture or wearing dark sunglasses. They also claim to be able to recognize one person per second, or 60 faces per minute. However, we cannot confirm this claim because we have not tested it.
