ZKTeco BioServer2
The BioServer 2 mini-server can be used as a back-end server for facial recognition devices under small scale application. BioServer 2 receives video streams from front-end cameras or captured photo streams, then perform 1: N face comparison, and reports or synchronizes the results to access control, time & attendance or surveillance system for further usage. With strong performance and directional optimization of the server-level facial recognition algorithm, the speed of facial recognition can easily reach 50 faces per second.
The BioServer 2 mini-server is equipped with a tensor processor which provides up to 3.2 TFLOPS dual precision peak computing ability and embedded 16MB of SRAM, while greatly improves the reasoning performance of artificial intelligence, it also reduces the power demand. The processor chip has reached millisecond-grade response in mobile lightweight universal face benchmark model Mobile-net latency test which is only a half or a quarter of industry mainstream chip.
