Camtraptions V3 sensor problems

[TractorGuy]

Hello,
I am new to the forum and looking for some advice with the Camtraptions V3 sensor.
A friend and I have a series of twelve trail cams placed around a local beaver pond.
The project started as a way to catch the poacher who illegally killed the first set of beavers.
However, after a year of watching the variety of animal activity around the pond, I decided to build a DSLR camera trap to take higher quality pictures. Mine is based on the Pentax K-70 and uses the Camtraptions V3 sensor and wireless receiver along with upgraded external batteries. Per the landowner’s request we are not using flashes, so the V3 switches are set to “daytime only” and the luminosity dial is set at seven o’clock position to function from dim light to full light.
I have placed the camera at the beavers’ favorite feeding site. A cellular trail cam is placed next to it. Every time the beaver visits the spot, the cellular trail cam sends a photo via text message.
Over the last two months, we have received dozens of cellular images of the beavers on the feeding spot in daytime light, yet only two times has the V3 sensor told the Pentax to take a photo.
It seems that while the trailcams sensors can detect the beavers, the Camtraptions V3 even set on highest sensitivity level cannot. Yet it has been able to detect ducks, dogs, and herons in the exact same spot.
The manufacturer has stated that this is because of the beavers’ wet fur. This is difficult for me to believe, as the regular trailcams can detect the beavers without any problem.
Has anyone else experienced this dichotomy of sensor performance? Does anyone have any ideas?
Thanks in advance for your insight. I know some of you have been at this much longer than I have.
