Someone can help me to solve my problem , where all my lead generation ads in facebook are keeps disapprove with the reason, not following their policy. Don't understand what is the error. Where my nature of business is selling and setup smart home system for house, office and high rise builing.

I am still don't understand on the polisy issue in smart home system.

Did you already appeal the decision?
With the rarely given information nobody can give you any advice.
It could be the Ad Copy, the creative, a blocked URL or the LP doesn’t comply with the Ads Policies

I am pretty sure that the reason is in your lp
