Detecting Trespassers

Poachers

Unknown trespassers in nature parks may often perform illegal actions, such as logging, charcoaling, or poaching. They are, however, also rather difficult to detect.

The Trespasser-sensor is a unique sensor designed to detect the presence or passing of people. If more than one sensor is being used, patterns may be distinguished that may urge rangers to visit the place and perform an inspection.

The Trespasser has been operationally tested in the Kasigau Wildlife Corridor, Kenya, the Dutch forests, and in Bardiya National Park, Nepal. It is available for NGO’s and park authorities as of November 2016.

Social network analysis

With the Trespasser you may conduct several forms of social network analyses. If new persons enter the area, the ranger may be alerted. When known poachers are entering the area, rangers must be alerted. For analytics like these we have set up WildCAT, a secure crime analytics toolbox. It is based on a license-free version of MarkLogic for data storage and the open source packages RStudio and Shiny (for analysis).

Robustness

If not connected to a solar panel, the sensor is designed to last unattended for 2 to 8 weeks, depending on scanning settings. If field conditions allow so, it may be connected to a solar cell, thus extending this period almost infinitely.

Like all other sensors the Trespasser is a networked sensor, which means that it sends notifications in real-time to a command post or other fast-responders. It’s operation may be monitored and (re)configured remotely. In areas without cellphone coverage, we help you to setup an alternative network (LoRa or mesh).

Trespasser is hi-tech made simple. The first time we place it with you. The second time you place it. Notifications and alarms will be sent to all registered fast-responders. Or just you. We monitor its operation and remotely re-configure it for you, according to your wishes.
