Your scoutguard camera has a PIR sensor. I have one too. Passive infrared is based on the same technology as thermal vision. Its a heat and motion sensor, not the same wavelength as other IR sensors.Seeker wrote:
I don't know if heat sensitive triggers for trail cams are available but I do know that my Nightranger monoculars internal IR illuminators are not detectable at all by almost all other Night Vision equipment except the very latest generation NV gear.
Though the trail camera lights up like an IR christmas tree when triggered, until such a time, it can't be seen at all. So unless a Yowie can see PIR, which would be a skill developed far better than most night vision devices, it will be caught on camera. If it is triggered, its too late.
Other than that, the paranormal sensitivities come into play. I do think a PIR sensor camera is a good tool for investigation and may well provide the long anticipated visual evidence of the big fellas. Experience may prove me wrong, but I am up for that.
P.S. It all boils down to this. Unless a Yowie has thermal imaging ability or the paranormal sensitivities, it will be caught on this trail camera should it cross its path. Personally, I would like to go to a hotspot and test this out.
