Principle of the UltraSoundGate 116Hnbm recording system

What are the advantages of Avisoft-UltraSoundGate 116Hnbm over other bat call recorders for passive bat monitoring?

  • Very long extension cables can be inserted between the microphone and the base unit/computer.
  • Unlimited continuous recording time. The only (theoretic) limitation is the size of the computer harddisk.
  • The included recording software offers a broad range of useful functions for passive monitoring applications (for instance Internet connectivity)
  • The PC platform ensures that the system can be easily integrated with additional (cost-efficient) components. It will be possible to incrementally upgrade the system as soon as new technologies (such as LTE internet services for instance) become available in the future.

In case it was sufficient to monitor and record signal frequencies below 80…90 kHz, the low-cost bat montoring system could be used instead of the UltraSoundGate 116Hnbm.
