Installation Specifications

Installation Scenario

The accuracy rate of face recognition greatly involves the installation location,
ambient light (such as too dark, too bright) and so on. In order to ensure to get
the best results, below are some installation suggestions:

Installation position should be a standard passageway or entrances or exits ways
with a particular direction of traffic.
Choose a stable lighting condition with adequate illumination. Light
compensation is necessary to ensure the facial features are visible under the
condition of insufficient light or backlight.

Examples of standard scenarios:

INSTALLATION & CONFIGURATION GUIDE

Examples of unsuitable scenarios:

Backlight Insufficient Light

Installation Height Requirements

1. The camera should be installed in the front of the passageway where it can

capture the face. The horizontal tilt angle of the camera must be less than <
25 °.

2. The camera installation must be elevated. This is to avoid the situation where

a face is obscured by the person in front of him in case they go through the
passageway closely one after the other. The vertical elevation angle should
be within: α=15±5°.

3. The covered Pupil Distance (PD) pixels must be greater than 40 pixels to

distinguish the face details from the captured image. The practical width of
detection area should be less than or equal to 3 meters with a 2MP camera.

passageway.
