There are a few different ways that automatic gates work. The most common type of gate uses an infrared beam that crosses the entrance to the gate. When a car or person breaks the beam, the gate opens. Another type of gate uses loops in the ground that create an electric current when a car or person drives over them. The current triggers a switch that opens the gate. A third type of gate uses sensors on either side of the entrance that sense when something is coming close. When something comes close, it sends a signal to open the gate.

When you drive up to the gate, a sensor senses the car and sends a signal to open the gate. The gate opens and closes behind you as you drive through. There are a few different types of gates: swing gates, slide gates, and barrier gates. Swing gates open like a door, slide gates move sideways along tracks, and barrier gates lift up and over like a garage door. The most common type of gate is the slide gate. They're popular because they're strong and can handle a lot of weight, They're also easy to install and can be used in both residential and commercial applications. Most slide gates use an electric motor to open and close them, but some manual versions are also available.
