I have not had much success with some IR cameras. The housing seems to get dirty or have a bug on it or something that causes the view to be whiteout in spots. I've had better success with bullet cameras and even better, seperate IR illuminators. On Vivotek cameras, it was so bad that I turned it off altogether!
On mission-critical environments go with/convince the end user to go with a seperate IR illuminators, or even a seperate camera's illimunators if you don't have to count on its view.

It might also be interesting to learn in which locations the IR cameras are or aren't being bothered by bugs, insects and spiders. I'm guessing rural areas might have more problems but I could be wrong.

We have not had much success with the Axis IR cameras. The range seems shorter than other brands, hot spots seem more prominent, and wet have had a couple of instances where the IR leaks out and creates a "halo" effect due to the angle that err positioned the camera.

john, we have used the avigilon bullet cameras with adaptive ir for over a year now and no problems with bugs... the older mjpeg2000 w/ir trim ring however those have given us problems... we installed those at a school three years back and they became a haven for small insects... we would clean them out about twice a year... we sealed everything but they still managed to get into the dome... we have also been burning some dahua mini bullet cameras at our office and have not had any bug problems with those... dome vs. bullet i do believe bugs can get into domes easier due to the serviceable cover, bullets are sealed tight however and bugs cannot enter... for now...

No problems with bugs to date
I use some AVIGILON IR cameras.
I have problems, with the old JPEG2000 dome, with the internal IR led. The problems, is the reflect between by the internal dome glass.
To fix it, i eliminate the space between lens and glass with rubber, to eliminate the disfraction.
Now i only use the BULLET AVIGILON CAmeras, and for me, it is the best IP/HD cameras of the world at this time (the 2MP is better than 3 or 5 MP).
