Two trains of thought here. If you have a villa and only use it for holidays then the Burglars usually only want to break in when they know you are there as the villa will have a lot more to steal than when it's empty. Burglar usually want cash, passports, jewellery. A wireless system from the U.K. would fit the bill.
If you live in the area permanently, then there will always be stuff to steal in your home so, probably the system that rings you and the police if the alarm sounds is the best.
