Pest Control and Trap Monitoring

Encounter Solutions Ltd presents Celium, a low-power, robust and flexible platform that delivers cost effective and efficient wireless trap monitoring to remote and rural landscapes.

Encounter Solutions Ltd is established as a pioneer of smart pest control and bringing the Internet of Things to remote applications, providing genuinely scalable and long range wireless trap monitoring, garnering both international and domestic attention.

At the heart of the Celium Platform is a drive to deliver significant long-term biodiversity gains.  By choosing Celium, customers will facilitate a transition to significantly more efficient and larger scale trapping projects that result in both ecological and economic gains.


  • Remote monitoring of traps delivers reduced safety risks to personnel and improved project cost-effectiveness by eliminating unnecessary in-field work
  • Automatic delivery of near real-time accurately time-stamped data facilitates informed project management and strategy
  • Standalone and light-weight, Celium Networks are easy and quick to deploy
  • Celium Networks can be deployed virtually anywhere in the world and do not require cell coverage or external power to operate
  • The Celium Networks’ lower path loss, superior range and non-line of sight performance means a minimal infrastructure is required for monitoring traps spread over large areas, especially in undulating topography, through dense vegetation and in wet weather conditions
  • Specifically developed for and validated in remote applications across New Zealand’s challenging topography, variable weather conditions and stocked farm areas
  • Celium is designed and built in New Zealand
  • Backed by a team with decades of experience in engineering, telecommunications, hardware, firmware and software systems

Celium Network

The Celium Network operates in the VHF radio wave band, optimized to provide long range, non-line-of-sight coverage.  The combination of narrowband technology and a lower operating frequency means the Celium Network can deliver superior range, especially in undulating topography, through dense vegetation and in adverse weather conditions.

Celium Nodes equipped with sensors and operating within a tightly constrained power budget gather data that is then transmitted to Celium Hubs via a low-power radio link utilizing a highly-efficient proprietary communications protocol.  Data is then backhauled from the Celium Hubs via satellite or cellular network to the Celium Cloud for processing and distribution.

 Celium Hub
