Digi Remote Monitoring Helps Study of Bear Hibernation

  • Digi International
MINNETONKA, MN - Digi International, which offers a wide range of wireless products, developed a remote monitoring solution for the Wildlife Research Institute that allows the institute to monitor bears in their dens during hibernation. One particular bear, Lily, hibernated deep in the Minnesota woods where there is no access to landline Internet service. To establish a camera uplink to Lily’s remote den, the Wildlife Research Institute is using the Digi TransPort WR21 wireless router which provides a high-speed Internet connection over Verizon Wireless’ 4G LTE network.

“We are allowing the Wildlife Research Institute to gain valuable insights into the activity of bears during hibernation by establishing a 4G connection in the wilderness,” said Joel Young, senior vice president of research and development and CTO of Digi International. “We have connected hundreds of thousands of remote devices throughout the world, and this application is a great example of how technology can be used to take control of widely-deployed assets.”

Using the video uplink, researchers could see how Lily prepared for birth during hibernation and how she reacted to the cubs just after birth. A second camera was also installed outside of Lily’s den that records activity near the den during warmer months.

Digi also helped the Wildlife Research Institute connect scales that detect when a bear is present in the den. When the bear steps on the scale, weight is recorded and the sensors trigger the camera to begin recording.
