One of the best security measures is the electrical fence (cerco electrico). One touch and the thief will be airborne.
Not really. If you are not talking about home-made controller out of an old TV transformer (which can actually kill easily), but a standard power-regulated fence controller - it will do no harm at all. Quite painful feelings , but harmless. Besides, how legal is to have an electric fence in this country?
I have a few network cameras all over my property and inside of my house here in La Mulata - no single attempt to break in. If even they try to crash or steal the camera(s) - before they do it - I will have the photos of them in my e-mail. Good stuff. Highly recommended.
