I know nothing about "cams", whatever that is, Jer.
You have awesome automatic misting systems from an american company called Pro-Products. The owner is Bob. Tell him I sent you. ( google it )
An automatic system, if it works, beats the spray bottles any day. You can regulate it to the "exact " needs of whatever environment you want to humidiy. Some are even apt to spray for just a few seconds every hour ( or whatever interval you want to use ).
What is it you want to spray? Is a natural type environment or tottally bare? Please elaborate so we can go deeper, my friend....
