1.2.3 DIGIOP® 3D camera and Oracle® Java™
DIGIOP® 3D camera uses Java applets on most configuration application web pages. If you are connecting to the DIGIOP® 3D camera
through Microsoft® Windows® Remote Desktop Services or a Citrix® server and using early versions of Java, some Java applets may
not load. Ensure that you are using the latest version of Java.
1.2.4 Data Quality
When configured properly, the DIGIOP® 3D camera should achieve 95% or greater in counting accuracy over a sample of 100+
visitors. Typically, the error in counting is under counting. When this device os configured properly:
•
The lens is appropriate for the mounting height and mounting angle
•
The DIGIOP® 3D camera can fully see people, unobstructed, in both lenses
•
The counting lines are positioned so that a person is tracked for a minimum of three feet (90 cm) prior to crossing a line
The following conditions can impact system performance.

* The DIGIOP® 3D camera assumes that people are walking on either a flat or evenly sloped surface. All points 4 feet on each side of the counting lines should have a
maximum height variance of 12 inches or 30 centimeters.
** Depending on the severity, this will appear as a calibration failure and will be automatically detected.
*** The DIGIOP® 3D camera should not be mounted so that it is attempting to count people through glass.
