Using Facial Recognition for timesheet verification

Using facial recognition with the Time Clock? Here’s how to train the facial recognition engine to recognise your staff.

Once your staff start clocking in and out using the Time Clock, you will be collecting images. Until you train the facial recognition engine, all icons will be red. You need to train the facial recognition engine to recognise them, so the camera icon will show as green when they are verified correctly, allowing managers to more quickly approve timesheets.

Reviewing timesheets

To view timesheet data go to Time and Attendance > Review timesheets, or use the Timesheet shortcut on the dashboard

Recorded data

In the Recorded section the raw or rounded times (if you are using Shift Rounding) that the staff clocks in and out are displayed.

The icon indicating clock in method also displays, for facial recognition it is a camera icon, which displays green when the staff member is verified, or red indicating verification has not passed.

Training the facial recognition engine

If a camera icon is red, it is indicating either that facial recognition has failed, or that there are not enough images on file for reference.

When you first start using the Ento Time Clock, you begin capturing images. Until you train the facial recognition engine, all icons will be red. Click on the camera icon to see the Facial Recognition Results.

Initially the results will be “Failed with a confidence level of 0% based on 0 training images”.  If the image is of a quality high enough to use for training, a green bar will display under the image offering to “Train recognition engine with picture”

Verified images

When reviewing timesheets it may take a few weeks to build up a bank of images. Keep clicking into the icons for staff for the first few weeks using facial recognition, until the green camera icons display.

When you click on a green camera icon it will display the staff image, and indicate how many images are stored, and give you the option of setting that image as the profile picture for that staff.

If you accidentally use an image that is not correct, simply click the dropdown box showing the number of images. Thumbnail size versions of the images on file will display, simply click the red Untrain button to remove one.

Considerations and troubleshooting

When considering where to place your Time Clock devices, if images are to be used for facial recognition verification:

  • If the camera position is fixed, ensure it is pointing at an area that staff of varying heights will be able to use, and not going to capture only half of the staff face – the whole face needs to be captured
  • Ensure there is more light shining of the faces of the staff than is coming from behind – if they are backlit, there will not be enough image detail and images will not be usable
  • If using a tablet ensure it is not upside down or capturing sideways images.


Blocking incorrect clocking in & out

Remember, facial recognition is a tool to assist managers to correctly authorise timesheets, by verifying which staff was clocking in and out, it will not prevent staff from clicking another tile in error.

If staff accidentally clocking out other staff is an issue and you need a time capture method that will prevent that, consider using PIN verification which will not allow someone to clock out with an incorrect PIN.
