Intruder Alarms - (Muscat)

Dear kind & nice people of the Internations!

Does anyone have any idea of how to go about getting an intruder alarm fitted in your home? Sorry if this is a silly question, especially if there are no burglar alarms in houses here, but just a little concerned about security if I were to move to a villa which would be massive compared to where I am now.

Any recommendations will be appreciated, thank you.
