how do gate remotes work?

698 views

I live an apartment complex and have to use a remote to open the one-way gate. Once opened I drive through and the gate closes on its own in a few seconds. Could I have closed the gate on someone’s car if I pressed my remote directly after they did?

There are installed sensors: motion, light, or weight. They sense your car, they know when you passed the gate and if another car drives behind you. These are safety measures every manufacturer has to incorporate in their products in order to sell automatic gates.

Other items with strict safety measures are escalators and elevators.
