This article explains how to position the Intellipunch clock for Facial Recognition.

The manufacturer recommends positioning the Intellipunch clock so that the bottom is 48" above the ground.

The zone in which the user should present their face for identification is 20-30" from the clock.

The field of view for the facial sensor fits individuals with a height of 4'8" to 6” at a distance of 20-30 inches from the clock. Individuals with a height of 6-6.5' should bend at their knees to position their face within the Facial Scanning Zone.
