University of IllinoisUsing the D7 at the University of Illinois at Urbana-Champaign

The University of Illinois at Urbana-Champaign operates a campus-wide security camera service. This service is a partnership between the University of Illinois Police and campus' centralized IT group, CITES. The University selected Scallop D7 cameras to handle several environments where our standard cameras were unable to perform at a high enough standard for facial recognition. The University uses two D7 cameras in a rectangular lobby of the main library. The lobby is approximately 100 feet long and 40 feet wide. The building lighting provides steady, but low light. The entrance to the library contains three sets of double glass doors. The doors face due east and receive very bright sun in the morning hours. We mounted two D7 cameras on the wall opposite of the double doors. By placing the cameras about 20 feet from the side wall, mounting the cameras at 10 feet on a 10-degree angle, we have been able to provide full coverage of all three entrances to the building as well as the entire lobby. There is more sun coming through the glass than we'd like, but the D7 has the capability to be adjusted to properly compensate.

The D7 has 5 sensors and is a 7 megapixel camera. The University is required to keep video for a minimum of 30 days. There was a concern that the D7 would require enormous storage space. We have found that its average frame size is larger than a single sensor camera that has megapixel capabilities. Conversely, when the D7 is compared to another vendor's IP camera that offers 180 degree views, the other vendor's camera's frame size is more than twice that of the D7. We integrated the D7 into our Milestone Corporate Edition infrastructure. There have been no failures to date with our Scallop D7 purchases. We have ordered more D7s and will soon test the M6-200 to see if it can meet some of our lowlight needs.
