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. We are Houston’s #1 access control system company.

Access Control Systems Gate


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. Many of these keypads can decipher several codes for specific operators and can have “hold-open” codes which hold the gate open. This feature is advantageous for hosting parties or guests.

Telephone Entry Systems

A number of homeowners prefer to have voice interaction with visitors to grant or deny access. Telephone or intercom programs provide for this and several  include video cameras to display visitors and even send the signal to a recording device.

Emergency Gate Openers

Emergency response teams need to get immediate access through a gate in emergency situations. Fortunately, in most states, owners of electric gate opener systems are required to have a device to permit for this. An emergency fire switch permits access for fire or police personnel, dependent on the fire switch. There are also systems that will allow emergency response personnel to use a button on their two-way radio. This is done to gain instant access to a barrier gate system.

Video Surveillance / Security Cameras

Video cameras for closed circuit TV (CCTV) or to view over the web can be fitted as part of an electric gate system. Cameras, oftentimes known as bullet cameras, with infrared technology for night vision or the ability to read license plates can be installed on fences or on columns. Also, pinhole cameras can be hidden in telephone or intercom keypads.

The video signal will need to be run back to the residence or facility utilizing a special co-ax cable or utilizing a telephone wire. Co-ax cable may be used for distances below 500 ft. 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.

Electric Strikes

Electric strikes are an access control program used to secure doors and pedestrian gates. An electric strikes elevated surface can, upon command, revolve out of the way permitting the door to be pushed open without the latch being retracted. A knob can nonetheless be turned to enable exiting from the secured location. Electric strikes may be fail safe or fail secure. Fail safe devices are unlocked when power is removed. Power is applied to lock the door. On the other hand, fail secure means that the strike is locked when power is removed and power is applied to unlock the door. Von Duprin and HES are well regarded manufacturers of electric strikes.
