Webcam HD-5000 autofocus disable
If anyone wishes to “permanently” disable autofocus on the MS HD-5000, there is a way.
You do not want autofocus in a car, especially with a camera looking through the screen, and the HD-5000 has a problem with autofocus as it is. On top of that it will revert back to autofocus any time +5v USB power is removed.
I kept coming back to this camera because it is far better than the Logitech 9000 in picture quality and in the real FPS that they will actually do, also because of its low cost and size. I run 720 x 1280 30FPS.
Of course you void the warranty and there is always the chance you could kill the camera if you do something wrong. Still at around $30 to $50 for the camera it’s not too big a loss. It really is a great little camera.
The first thing to do is to turn off autofocus in software and move the software manual focus bar all the way to sharp distant focus, now unplug the camera, this ensures the focus motor is in the correct position.
UPDATE: I have rewritten this intro to the thread as thanks to input from BADMOPAR you can easily pry the front plastic glass and trim from the camera face.
There are two screws behind the trim, remove these screws and the housing comes apart easily.
The PCB with lens is screwed to the back part of the housing and the lens is screwed to the PCB.
There are two solder tabs on one side of the lens, I heated the tab closest to the edge of the lens and used a pin to pry it away from the PCB solder tab, the metal connecting tab is very flexible and moved easily.
I reasoned that this could have been the supply to the Autofocus motor and it appears I was correct.
You need to be careful not to splash solder on to the small SMD chips near the tab as you unsolder it. I used a bench magnifying glass to unsolder and check for any solder spray. Make sure there is no dust or rubbish on the lens or inside the front housing and reassemble.
Mine is working great, no more stupid autofocus.
