1.8mm 170 Wide Angle Lens, 1MP IR Board Lens for 1/3" & 1/4" CCD Security CCTV Camera, Standard, Plastic Construction, C Mount, Fixed Focus, Default

Oumij 1.8mm CCTV Lens,170° Wide Angle Lens,1MP IR ....Replaced the standard lens on a WYZE cam V2 with this lens. Compatible with case. Good image quality. Focus adjustable. I'm guessing their claimed FOV is diagonal (or on a different sized sensor) as the horizontal field of view appears to be ~ 130 degrees. I did not check IR quality. Part of a search for a good nearly fish-eye lens.Had to mostly disassemble the WYZE camera in order to install lens. A tiny knife + isopropyl alcohol is sufficient to remove the 'glue' that is on the threads of the default WYZE camera lens.It would be best to disassemble the camera to the point of removing the visible / IR filter changer (this requires bending but not breaking plastic) before attempting to remove the glue.Disassembly is straightforward (screws and plastic snaps), video can be found online. Glue removal is rapid with high purity alcohol.
