Removing the filter will allow you to enhance the IZON with a third party IR spotlight, but it will bugger all the colours up, if you see the photo in the final step. Please leave a comment too! It's my first instructable
Step 1: Open the Camera
Have a look at your IZON and you will notice the cylinder is made of two parts. Unplug it all and take it off the base.
Now you can prize them apart. I think start at the top as there is the heat vent to get in there, and the tab is smaller if you look in the photo.
Take care not to apply too much pressure, if it doesn't open move to another part, be patient. and don't dig the screwdriver in too deep and scratch the PCB.
I didn't take a photo of the removing part, and hard to hold a DSLR at the same time ha, so just see the photos of how the clips go together.
