Deployment SIte Two - Summary of Month

This site has now had a month of deployment and the decision has been made to move the unit to depolyment site one.

In summary - the profile was the present standard profile: Daytime is a regular stoat call.   The nighttime profile cycles between five different basic sounds: the same stoat call that is used during the day, two possum calls and two baby chick/bird calls.    The purpose of the trial is to test the unit, the power status and see if it can have a basic effectiveness.   Some of the sounds have not been professionally recorded and were located as freely available youtube recordings.   These remain an area of significant targetting and improvement in the future.

Battery Power/Solar Charging of Unit: At present this unit has been charged in a solar power context only for a calendar month there was no additional boosting through a mains power system.   The unit has been delibrately placed in a position of full sunlight.  As a consequence the unit was nearly successfull.   It was able to operate on full power during the day and had enough charge generated to last most of the hours of darkness - there was some struggle to power the unti through a full cycle in the morning, but with the first daybreak the unit was then able to operate as expected.   In a shaded situation the unit would require 'boost' charging to alow it to operate fully.   Significant changes can be made to the frequency of the sound emitting, such as a the timing between bursts and the frequency - this was intended to 'push' the unit in a trial situation and it did exactly that.

Weather Exposure: The unit was placed inside a tunnel trap, and further inside PLA Plastic (3D Printed) boxes.   There was also a moisture packet placed inside the box.   These precautions were enough to ensure that no moisture combined with the unit for the month. 

Pest Interaction with Sound Lure/Trap at Location: There was repeated activity with hedgehogs at the site, including two who attempted to enter the tunnel and were trapped as a result,   The tunnel was next to a maize paddock so we were expected rats or mice (hence the trap) which did not eventuate.   There was no other recorded activity with the exception of domestic cats.   There are possums operating in the general area.
