A little screen test...

Here are some more hedgehogs in my garden including one little fellow who's got a bit of an itch! To get the best picture from my infrared camera I have laid down two rubber car mats which prevent infrared glare from the paving slabs, and I have also used the low-tech method of taping over some of the infrared LEDs on the camera itself so as to reduce glare in the centre of the picture - which is often on the hogs themselves.

It might be a low-tech solution but it seems to work!
