This security system uses a metal ball inside a metal pipe. When the ball remains still, it touches two of the electrical contacts. This completes the electrical circuit. If the ball moves, it breaks the circuit and opens a switch. If somebody makes the car move, the system causes the horn to sound It makes the car lights go on too. If somebody hits the car a few times, it makes the siren sound.		The ExitGuard is mounted over the door handle. It has a battery-operated alarm. When somebody breaks open the ExitGuard, this causes the alarm to sound. The ExitGuard allows shops to secure their emergency exits. This stops people from using the exits to enter the shop. But it lets people leave the shop in an emergency.

	If you keep expensive equipment in your workshop, fit a burglar alarm. When the doors and windows of the workshop are shut, the electrical switches are dosed. This allows electricity to flow around the electrical circuit. If a burglar forces open a window, this breaks the circuit. This causes the burglar alarm to sound. If your workshop is a long distance away, install the alarm buzzer inside your house. This allows you to hear the alarm when you are inside your house.
