Access Controller – Manages commands, directs the action of other devices.  For entry devices is the programmable brain for access cards, codes, transmitters.  Tracks all activations and denials by location with reporting capability.  Managed from a user PC with programmable software.  Not required in all applications

Bar Code Reader – A reader capable of reading and interpreting cards using bar codes.  Most commonly seen and used in retail stores.  On gate applications bar codes are placed on vehicles for entry into secured facilities and communities.

Biometric Reader – A reader that makes its identification through individual biometric data (fingerprint, voice, eye) to activate a device.  Used at high security facilities.

Card Reader – Reads cards (normally credit card size) for operating or accessing a device or equipment.  The card must be inserted or swiped to activate the device.  Many types exist, depending on number of users, features required and security levels.

CCTV – A term used in video applications that is point to point.  Always uses video cameras of varying quality.  Quality required depends on primary application.  Primarily used for security surveillance.

Control Panel  – An electrical device for closing or opening electric control circuits, signaling, and electric interlocking, as well as manual remote switching of devices and equipment. A distinction is made between control push buttons with an automatic reset, whose contacts automatically return to their initial position, and buttons without an automatic reset, with mechanical or electromagnetic interlocking. Control push buttons may be of open, sealed, or dust-proof and moisture-proof designs.  They are custom made and control many entry devices from a central location.

Emergency Access – Various devices to open the system by local emergency services in the event of an emergency.  Usually determined by local code.  Key, radio frequency, siren frequency are examples.

Intercom – A two-way communication device with microphone and speaker at both locations.  Can be equipped with push button controls to activate device or equipment as well as video.

Keypad – A keyboard for operating a device or equipment.  Many types exist, depending on number of users, features required and security levels.  Includes wired and wireless.

Photo beam – A beam of light that when broken triggers a device or equipment.  Primarily used for safety in automated gate applications.

Proximity Reader Is a reader that uses “smart cards” or “fobs” that can be read without inserting or swiping into the reader.  The cards or fobs are normally presented near the reader to activate the device or equipment.  Types vary depending on application, space available, number of users and security levels.

Push Button – A button or knob that opens or closes an electrical circuit to active a device or equipment.

Safety Edge – A strip form on leading or trailing edge of a gate that when contacted will open, reverse or stop the machine.  Can also be mounted in an entrapment zone.  Used for safety purposes.

Telephone Entry System – A control system that allows users away from the device or equipment to use a phone (including cell) to control the device or equipment.  Models vary depending on number of residents, programming features needed.  Most current models come with many features such as; timers, call forwarding, remote programming and security features just to name a few.

Traffic Loops – An induction loop.  Used to detect metal objects (vehicles).  Once detection occurs provides input to device or equipment for specific action.  Action can be open, safety, reset, alarm and many others.

Transmitters/Receiver – An electronic device that transmits and receives communication signals.  The simple description is garage door remotes.  All types exist with varying ranges, features and security levels.

Touch Panel – Same as control panel but uses latest touch screen technology.

Vehicle Detection Probe – A device that senses mass and movement (vehicles) to activate a device or equipment.  Generally used as an exit device in residential applications.

Vehicle Identification Reader – A wireless, non-contact device that automatically identifies and tracks (vehicle tags).  Once read the receiver will active a device or equipment.  Many applications but most commonly seen in toll booth applications.
