Infrared night vision digital camera/camcorder

Step 11 Unscrew the lens

With the case open, you now have room to firmly grip the camera module with a pair of pliers, vise-grips, or other suitable gripping tool.  With a second pair of pliers, twist the lens module (sorry I couldn't take a picture of this action because I only have 2 hands, but you can see some damage to the edges of the lens where I was gripping the lens with the pliers; this damage will not affect anything, and it will not be visible once the camera is re-assembled).  The glue will still be holding fairly tightly, so don't try to unscrew the lens in one motion.  What you need to do is repeatedly apply force in both directions (loosening and tightening).  The repeated action will gradually break the remaining glue, it can take several minutes but eventually the lens will start to turn freely.  Unscrew it all the way and remove the lens from the camera.  The removed lens is shown in the second picture, face down on the table.
