Access Control Systems

What are access control systems? They are systems that enable an authority to control access to an automatic electric gate in a given residence, commercial, or government facility. This is accomplished in a number of unique methods. Usually access is achieved by means of a code access on a standard keypad, phone intercom access, or through video entry programs. Also, access can be achieved through a remote transmitter from a vehicle, biometric readers, proximity readers, emergency and gate openers. Most recently, by means of Bluetooth access from a mobile device.

Keypads

AAS-keypads- This kind of device has a numbered keypad and operators must input a preset numbered code. The code is deciphered by the keypad that sends a signal to the driveway gate operator to open.

From 500 ft. to 1000 ft., telephone cable may be used with a non-powered balun on either end. Powered baluns are necessary on both ends for distances over 1000 ft.

Access Control Systems – Proximity Cards and FOBs

Proximity card devices are composed of a card reader and unique cards attuned to precise transmission codes. The reader transmits signals to the cards via antenna coil which receives the signal and then returns the signal to the reader with its unique code . The reader will then verify or deny verification of the cards code. A number of Telephone Intercom Systems cohere to the proximity detector as a Wiegand instrument and are designed to decipher the codes from the prox card reader and validate them from their own database.

Access Control Systems Card Readers

An innovative system that uses a highly secured card verified by the card reader. The card consists of the code which runs through a verification process at the reader.  Also, these card readers may be used as modular add-ons to numerous Telephone Entry systems. HID is a well known manufacturer of these card readers.
