Final Prototype Deployment Activations/Weather Situations

Following three days of rainfall, wind and generally poor weather there has been two significant activations on the single unit deployment at site one.   There are three issues here that are worth noting. 

Firstly the IP Box which has been waterproofing the main portion of the electronics has work as expected.   There has been three days of rain and while the box has been at the base of a tree offering it some basic protection (as opposed to being placed inside a trap box as eventually it will be) the unit has been exposed to the elements.   We have stated that the solar panel and speaker are being housed separate from the main unit and they are more exposed to the elements, and there was evidence of rainfall on both.    For the main unit there is no evidence of moisture inside the box itself which is housing the main electronics (and the expensive parts of the units, see 'economic breakdown' in a different post on this blog).

The two activations that are present shown on the camera are represented by a cat which can be seen in the above photo.  It is clearly seen on a series of photos that take place at 8:25pm.   As noted the camera needs to be reset so that it reflects daylight savings and the correct year.

We have shown evidence in the past of the unit with the basic sound profile (which we are using again for current testing) which has two possum sounds, two chick sounds and a stoat sound consistenly attracting cats and feral cats to the unit.  The second activation which can be seen clearly in the photographs is the large brush tailed possum which arrived at the unit and was in the vicinity of the unit at 9:15pm. 

The final issue relating to the unit is again the question of the battery unit and solar panel charging.  There has been three days of rainfall and overcast weather.   The suspicion is that this has limited the ability to charge the unit.  There is clear evidence that the unit has been working during darkness (as shown by the photographs) however by the early morning the unit has stopped.  This is something that has been experienced with the unit.   The speaker deployed with this unit is a 4w speaker.   Once the unit has been moved into morning light the unit has started immediately operating exactly as expected (using the day profile).    We are going to run trials with different strength speakers and also experiment with the solar panel in a location that has more direct access to sunlight, in addition we are charging the unit fully in daylight (solar) and will then place it in semi-shade for the deployment.
