The latest in facial recognition access control.
PSILOC represents the newest generation of biometrics design from PSI.
PSILOC builds upon a foundation of 5 years of Biometrics design and implementation, with currently over a million
faces processed every day by Perception Sensors & Instrumentation imaging systems worldwide.

High Quality Imaging
The PSILOC uses imaging technology designed by PSI to capture high quality images of the facial region
even in high vibration environments, making the system uniquely suitable for installation in public
transportation systems, vehicles, high value plant equipment and machinery.

Irrespective of whether its the subject in motion or the PSILOC, the ideal image will be captured
resulting in optimal performance of the facial recognition system.



The PSI-2 is a fully integrated flow computer, offering a wide range of options to simplify and reduce the cost of gaseous flow measurement derived from differential pressure sources. The integrated transducers and computational unit provide the ultimate flexibility in D.P. flow measurement.

Standard Features

  • Reports in velocity, volumetric flow or mass flow
  • May refer to standard temperature and pressure
  • Linearisation function to compensate for variable flow profiles
  • Two 4 — 20mA current loop outputs
  • Serial interface for PC configuration
  • Simple to install
  • Modbus interface

Prox-Card technology

The Prox-card reading technology in PSILOC resullts in a contactless interface, enabling PSILOC to be used in environments where hygiene importance is paramount.

Each prox-card features a unique identification to speed up the recognition process through large databases of facial recognition templates, ensuring consistently fast verification.
