A huge array of ultra bright blue LED's are very effective at keeping thieves away. Just have to pulse them with the right frequency. Makes them feel sick to the stomach. Also, no noise to wake up the neighbors. :)

That is the best that you have a danger pet on the home for protecting from burglars . That is as joke of the burglar and danger pet.

A burglar go into in a house, he found that the home is full the advice of the danger pet("Careful", "Dangerous animal") . Until he arrived to room where he found a  little cage inside it , there is a little parrot.
So the burglar begin to mock the parrot until the parrot shout " Sultan, Attack" ,then a huge dog appears. :-DD :-DD.

Now reallly, apart of the alarm system , you have to have a pair the dogs (Style Spanish Mastin , Alano or other dog) on his garden.
