This squirrel took down my camara for some reson
I put a battery powered WCO version 1 cam on my fence runner once and a red squirrel took it out in less than five minutes. Evil creatures.
This is the video
He was just adjusting the field of view for you. Looks like the day/night shutter changed everything to purple also. You could have added the video to your original post, just tap the pencil on any of your post and you can add to, change or remove anything you want.
Squirrel knocked your IR filter on during the daytime (hence the pink/purple tint). You can fix that by turning the IR setting on and off again btw.
Gotta love the little curious critters.
(Edit: Antonius beat me to it)
