Topic: Security Central / Covering Obs Cell camera's

Good day;

I am would like to know how people have solved the uncovering of obs cell cameras – there are occasions when inmates use wet toilette paper to covera the camera lense. typically this is happening after the inmate has been allowed some effects and then escalated again.

I am considering compressed air; as we can retro fit a nozzle in the case of the camera, then use the air to clear the covering.

Has anyone tried this? Or any other creative solutions to maintaining visual on inmates?

thanks
