Take a look at history.
A short history of automatic gates.
The idea of an automatic gate dates back to ancient times when humans first started building structures for protection and privacy. The concept of a gatekeeper was introduced to monitor who enters and exits the complex.

However, the concept of automatic gates was not introduced until the mid-19th century during the industrial revolution. These gates were originally used for train crossings and operated using electricity. The first automatic gate on record was invented in 1885 by a railway engineer named E.P. Thompson. Thompson’s gate was designed to detect the presence of an oncoming train and close the crossing to prevent any accidents from occurring.

However, it wasn't’ until the 1920s that automatic gates became widely popular for residential and commercial use. These early systems were operated using mechanical devices such as pulleys and cables, and they were often unreliable and prone to breakdowns.

In the late 1960s, the first motorised automatic gate was introduced. These gates were operated using electric motors, and they were far more reliable and efficient than their mechanical counterparts. These early motorised gate systems were often operated using a remote control and were commonly found in commercial and industrial settings.

The development of automatic gates continued throughout the 20th century with the introduction of new technologies such as sensors, timers, and digital controls. These advancements allowed for the development of more sophisticated and integrated gate systems that could be customized to meet the specific needs of the user.

Today, automatic gates are commonly used in residential, commercial, and industrial settings. They are used to provide security, convenience, and access control to buildings and properties.

In conclusion, the development of automatic gates has come a long way from their earliest origins. From being used primarily in railway crossings to now being an important part of our daily lives, automatic gates have significantly improved both security and convenience. As technology continues to advance, we can expect to see even more sophisticated and reliable automatic gate systems in the future.
