Changing A Foscam FI8905W Lens

 

Lens change instructions
These are not my instructions – I have just converted a PDF which was sent to me by John Peabody via the DigitalHam contact form. The PDF had no copyright information and I assume it was created by the eBay seller of the replacement lenses. I have only published this to give an idea of the job – I imagine if you buy a lens your seller will provide some instructions with it.

1) Remove the case from the FI8905

2) Remove the screws and take out the IR board and lens (leaving the 4 screws in place)

7) If you cannot twist the upper part of the lens, loosen the small white screw on the lens socket. Now twist the upper part of the lens to sharpen the image.

8) Replace the IR board, all the screws and the cover, power up again and check the image.
