Are you worried about the camera malfunctioning due to the dust, or more if it will be able to see what needs to be seen trough the dust ?
Mr. Khethiwe, There are many questions to answer before making a firm recommendation, but based on what little has been discussed here, Digital Watchdog makes a series of cameras with "Self-Cleaning" domes. The Cleanview has a hydrophobic coating on the dome that claims to repel water, grease and dust to alleviate spotting and smudges. It may be worth your time to investigate. Good luck.

A while back I installed some domes and PTZ with domes in a dusty auto body shop. after just a few days, there was a layer of dust all over the dome that was making the image pretty bad. I realized that the static electricity from the dome was pulling the dust to the dome like a magnet. I ended using anti static drier sheets to apply on the domes and then polish it in with a soft cloth.
It seemed to help a lot with the dust. Also I believe there are also antistatic sprays you could also try.
I would recommend setting up a regular cleaning maintenance schedule with the customer in a dusty environment like this.

Thank you Jeff. Can you kindly share with the name and specs of the spray that you know of?
we do offer some fully dustproof housings that can be equipped with wiper/washer for crisp images 24/7.
In this enviroment, we offer an air barrier that will prevent The deposit of dust or debris on The window itself.
You can look at this ONXAB2 air barrier
