AI Facial Recognition in Security: What It Can and Can't Do

Most facial recognition deployments run on the same 1080p-to-4K, 15-to-30-frames-per-second camera feeds already installed for ordinary video security, so the marginal hardware cost is often close to zero.

How AI Facial Recognition Actually Works Every facial recognition system follows the same three-step pipeline: detect a face in a video frame, convert its geometry into a mathematical template, and compare that template against a stored gallery.
