Well, turning down the PIR movement sensor sensitivity solved the problem of capturing unwanted mice videos on the two square metres of riverbank I’ve been monitoring with otterCam 1 for the last four days, but there were 37 video clips of the pheasant pecking and clawing the ground day and night on the memory card this evening.
I setup a second OtterCam, fitted with a close-up lens, at a different position along the riverbank yesterday. Unfortunately, I positioned it right behind the entrance to a mouse nest, so I ended up with fifty-five mouse videos on OtterCam 2 when I checked its memory card this evening.
Maybe the reason I’m not attraction otters to my camera traps is because the river level is too low. I usually manage to capture an otter or two on the first or second night of putting an OtterCam out.
