Access control is a system which enables an authority to control access to an automatic electric gate opener or operator in a given residence, commercial, or industrial facility. This can be handled in different ways. For example code access on a basic keypad, telephone intercom access, remote transmitter access from a car, proximity readers, emergency gate openers, or bluetooth enabling access from a cellular phone.
This device has a numbered keypad and users must input a numbered code in order to open the gate opener. Some of these keypads can hold hundreds of codes and can have hold-open codes which hold the gate open. This can be useful for parties or when you expect a visitor.
Proximity card devices consist of two components: a card reader and special cards attuned to specific transmission codes. The reader uses an antenna coil to send signals to the cards which receives the reader’s signal with its own antenna coil. Then it reflects the signal back to the reader with its unique code . At this point the reader may verify or deny verification of the card’s code. Some Telephone Intercom Systems connect to the proximity detector.
Some customers like to talk to guests before letting them enter. Telephone or intercom systems provide for this and some include video cameras to display visitors and even send the signal to a recording device. This option is ideal for homes, gated communities and apartments.
Similar to garage door remotes, gate openers use gate remotes as access devices. A receiver, usually installed inside the gate opener, receives the signal from the remote when you press the button and sends a signal to open the gate.
