If you want to identify strangers based on a datbase of photos, what you are looking for is facial recognition or facial surveillance. It is not face detection.
Face detection is simply identifying and automatically capturing a picture of a face. It does not match it or alert on it. For example, a few IP camera suppliers include built in facial detection, but not necessarily face recognition.
As for facial recogniton / surveillance, make sure the supplier has experience in facial surveillance specifically. The difference is whether one is matching against controlled subjects (i.e., a person stares at the camera), vs a person just walking by (e.g., your request for strangers walking into the building).
I could not recommend any supplier that does this well.
But let me ask: how accurate does this need to be? how tolerant are you to mistakes? How much are you willing to spend per camera / door?
AFAIK the 2 most popular solutions are HERTA and Cognitec.
HERTA is a simple solution vs Congnitec which is more heavy weight and from what I understand Herta licensed its algorythems from Cognitec.

Thanks John and Itamar for your response.
For John, Yes you are right I mean facial recognetion.
To my knowlegge is that the customer is using Avigilon IP cameras, but I do not have accurate answers for the rest of your questions.
All I have is just a request for such a solution.
I suggest a company called facefirst out of california. They also license from cognitec but do the processing in the cloud to make a little more lightweight on the server.
The ultimate challenge for the Facial recognition system is how low is the false alarm rate so that innocents are not troubled by the law & order force and how many criminals were identified accurately to prevent the crime.
I would like to know whether any facial recognition software is available in the market which surveillance professionals can say that we can go for it without having to dwelve too much into the failures of the software.
