There have been cases of plaque formation on the first objective lens - the IR filter.Sadly despite thorough cleaning of lens and CPL filter there is no improvement in quality..
The footage is the same now even when the sun is not present, it used to be really good footage and has spent 18 months attached to the front windscreen whilst my A119 has been operating out of the rear windscreen attached to a suction mount which also gave me excellent recordings whilst attached to the suction mount...Is it the same without the sun ?
Also, how far away from the glass is the camera.
I'd be interested to see what the footage is like without the glass in the way, rule it out.
Thanks for info re plaque formation, I will slightly raise the lens upwards to see if it helps, not sure how confident I am at opening up the camera and fiddling with the matrix board....There have been cases of plaque formation on the first objective lens - the IR filter.
You need to disassemble the DVR, disconnect the holder from the matrix board, see if there is any plaque on the IR filter and matrix.
If everything is clear there, adjust the focus.
P.S. Raise the lens slightly, then everything will not be flooded with white.
I wonder what causes that plaque.
Disassembled. The holder is really plastic. The lens on the back, or rather the IR cut filter (?), Has a cloudy coating. I rubbed myself hard with a cotton swab. It seems not completely erased. But it seems to have gotten better.
The holder was glued to the board with some kind of glue, and the board with the matrix was somehow sticky. Probably, this glue evaporated and gave a coating ...
By the way, this IR filter accumulates three drops on the lens. I thought about throwing it off and washing it separately, but it holds on tightly.
Thanks for giving it a try. Hopefully someone may know the cause of this failure. I am wondering if smoke is on the inside of the lense on the sensor. Grasping at straws now but that's the next step I would go given the camera is almost useless.Sadly despite thorough cleaning of lens and CPL filter there is no improvement in quality..
And all you really wanted was advice about A119V3 and you stumbled into a hornet’s nest of boffins. Lol.Thanks, have no tinted rear screen but will remove the CPL filter and see if anything different, am also going to set the EV exposure from 0.0 to a minus setting but I think the camera has developed some sort of fault.. Will also try and take some footage with it away from the car as per Kremmen`s post above to see if any difference...
