Green layer on images

Hello

we have purchased 5 cameras (aircam) but 2 of them give images all in green. The settings are the same as the camera that is placed 2 m further on (Hue, Saturation, ...) and the light-spots in the room are almost identical (big lamp in front).

What could be wrong?

I have sent a support request and received a ticket number but no reaction after a week, not after a status request.

Re: Green layer on images

Try the latest firmware at the top of the forum here . 1.1.3.
If that does not do it , unscrew the lens on one and check if it has what looks like a plastic film layer on the back side.

status update

hello,

the firmware from 1.1 build 10874 to 1.1.3 build 11931 did not solve my problem.
There is no plastic in front of the lens.

I also changed the framerate from 30 fps 2048 bitrate to 10 fps but that neither solved it.
The image in iSpyServer and on the live view stays green.

Anybody an idea?

Re: Green layer on images

The plastic I was referring too is on the back side of the lens. You have to remove the cover then the lens with the spring around it.
Don't scratch it.
A normal UN IR filtered lens will not have a thin wafer IR filter on the back side. This will cause a green blue or yellow tinge too a day time image.
The Aircam original lens has this thin wafer IR filter. On the inside /back side of the lens.

Re: Green layer on images

Yes, the IR filter should be on the back of the lens and you can't see it unless you remove the lens.

This site has a picture that looks very similar to what you will see if the IR filter is there: http://www.instructables.com/id/infrared-digital-camera---the-real-way/step6/take-out-the-IR-filter/

If the IR filter is missing, that would explain the discoloration.

Hi Mario,
Is it possible to get screenshots of these images emailed to me (matt@ubnt.com)?

Thanks,
Matt

Re: Green layer on images

Jumping on a tangent slightly here... We've run into the same discoloration issues using lenses purchased through eBay (the seller that has been recommended many times on here by others). Do those lenses not have an IR filter? If so, is there a recommended source for higher zoom lenses that do have it?

Re: Green layer on images

I bought several and NO they don't have a filter.
I have also searched HIGH and LOW for what your seeking with no luck at all.
Maybe if one could find a place that can get the material and stamp out a few thousand they could be peddled here. A tiny dab of glue and it's set.

Re: Green layer on images

Crap, so we're basically out of luck for daytime use with these things if we want a different zoom level?

Re: Green layer on images

For now I'm afraid so.
I wonder if we can get Matt to look into this , Maybe find the supplier of the 4mm stock lens and then get after a retailer to order a few hundred 8 and 12 mm lens.

Re: Green layer on images

If anybody knows where to get a sheet of the IR filtering material, I'd consider ordering one to cut out some filters. Not being able to change the zoom on daytime use cameras is killing us.

Maybe you should have spent $2500 + on a nice PTZ camera instead? :manhappy:

Or wait for aircam pro!

Re: Green layer on images

Considering the basic Aircam does -almost- exactly what we need, that wouldn't be an easy sell. All I want to do is change to a different fixed zoom without wrecking its daytime images.
