Card access relies on keycards, normally flat and rectangular-shaped pieces of plastic, that are presented to a card reader. Access control card readers are used in physical security systems to read a credential that allows access through controlled points, often a locked door. Access control readers offered by Ameritech Systems are classified by functions they are able to perform and by identification technology. Types include a magnetic stripe, bar code, smart card, and proximity cards. Card access is classified as Magnetic strip, Bar Code, and proximity cards.
A keypad alarm system is a basic alarm system with a low-voltage circuit that involves sensors on doors and windows. When a window or door is opened, the electricity through the sensor is interrupted and the alarm will sound if activated unless a code is typed into the security keypad. Some of these alarms also use motion sensors and are triggered when motion is detected inside an area. Keypad alarms, which are available in wired or wireless types, offer several advantages over other alarm systems. They allow the user to control all the access points in a structure, giving access only to select people. Wired keypad alarm systems connect to a control panel. The wires, hidden in walls and various crawl spaces, go to sensors placed on doors and windows, and the keypads themselves. Instead of wires, wireless keypad alarm systems use radio transmitters to send signals to each other. The same alarm effect is created when doors or windows are opened without entering the code into the numeric keypad.
Gate access is a form of access control in which physical authority is allowed in through a gate or doorway. This gate or doorway would be operated by a remote or automatic station and would only allow access to people permitted by the system. For instance, a garage door or driveway gate to a community may would only allow the residencies to enter, and thus would ask for a key card of keypad number to gain access.
Like audio intercom systems, video/audio intercoms may be installed outside or inside a home or place of business. In addition to clear sound, video/audio intercoms offer sharp images, made possible by an audio and video transmitter and receiver in a single cabinet. Unlike audio intercom systems, the advantage is that users can see potential visitors and other conversation partners, which creates more security and increased peace of mind. We install a variety of audio/video intercom systems ranging from panning and zooming to video memory so you can check on previous visitors.
