Watch the video below, did that guy just claim that this surveillance system can search through 36 million images in one second or am I crazy?

Its easy when all faces are exactly the same. LOL. =)
You are being watched. The government has a secret system, a machine that spies on you every hour of every day. I know because I built it. I designed the machine to detect acts of terror but it sees everything. Violent crimes involving ordinary people, people like you. Crimes the government considered irrelevant. They wouldn't act, so I decided I would. But I needed a partner, someone with the skills to intervene. Hunted by the authorities, we work in secret. You'll never find us, but victim or perpetrator, if your number's up... we'll find you.

No, not crazy. The comments in the video match what I expected - the stored images are being preprocessed sometime before the '1 second' match. Facial recognition technology is well developed both for detecting the location of faces in an image and categorizing their features.
It's that categorization that makes it so fast - you're reducing it from 300+KB of pixels to maybe 32 bytes of data representing the relationship of key points (distance of eyes from center, nose, etc). Each frame is preprocessed to detect faces and then create hashes of each face in the frame. To find a particular face among your stored security footage you run a match against that big list of face hashes. Close matches are then referenced back to the original video frame where a more detailed comparison can be done.
For comparison I've reached over 1 million image (not face) hash comparisons per second on desktop hardware. 36 million seems well within reach.
Sigh, fail on my part, I should have read the comments before I pasted mine above. But yes +1.You are being watched. The government has a secret system, a machine that spies on you every hour of every day.
It can scan 36 million faces in one second.... provided you do lots of preprocessing on the pool of data to be scanned on the way into the system. That's not really that impressive algorithmically unless the pre-processing is really light weight.
