Genus Biometric Reader - Adjusting Sensitivity and Security

Last updated 7/31/12

HourDoc Bio-Reader Adjustment Guide

How to Access the Sensor Settings

  1. Log into the clock as a “Supervisor” by pressing "SUPV" and entering your supervisor pin followed by "E".
  2. Press the down arrow key until “Sensor Options” is displayed.
  3. Press the “E” key to select “Sensor Options”.

Two Types of Sensor Settings

Global Settings – Applies to all people enrolled in the clock (not recommended)

  1. Sensitivity - Options are 0 – 7; lower numbers are less sensitive.  Standard is 3 or 4.
  2. Security - Options are 1 – 3; higher numbers are more secure.  Standard is 3.
  3. Image Quality - Options are 0 – 2; lower numbers mean lower quality.  Standard is 1.

User Settings – Applies only to a single user and adjusts only Security

  1. Enter User ID and press "E"
  2. Select Option of 0, 1, 2, or 3 and press "E" to adjust security; higher numbers are more secure (see definitions below).

Security - This determines how many points are made between the lines on a finger.  A higher security setting means more points are required to match between the template (enrolled finger) and the scanned finger (when clocking in).

Sensitivity - This determines the amount of time a person must keep their finger on the sensor before a reading is taken.  A lower sensitivity setting equals a less sensitive sensor, meaning a person will have to keep their finger on the sensor for a longer period of time.  A higher setting means the finger will be read faster, but can affect security and quality.

Quality - Represents how clear the "image" will be (much like the quality setting on a camera).  Note that the sensor does not record the actual finger print, but captures points on the ridges/lines of the finger print.  These finger "templates" can only be ready by the clocks and could never be used by any other person or entity to match someone's finger print.

Adjustment Effects Examples

Bio-reader settings can affect how the clock is able to identify a specific user.  Typically the default settings will provide adequate results, however in some cases it may be beneficial to adjust the settings due to the environment of the users.  For example, at a construction site, it may be advantageous to use the following settings:

Sensitivity = Less sensitive (Causes finger to stay on sensor longer)

Security = Medium (Avoids false acceptance of the incorrect person)

Image Quality = Maximum level (Image Quality allows more data points to be available)

For construction workers where their finger templates may be less than perfect due to job duties, it forces the person to leave the finger on the sensor a second longer allowing the bio-reader to gain a better quality level of the finger presented.


Bio-reader success always starts with good enrollment.  If enrollment is not done correctly then the problem is propagated throughout the system causing user frustration.  Ensure that during enrollment that fingers are place flat on the sensor and not rotated.  Avoid using finger tips and finger placement that is not in the center of the sensor.
