Talkback or door phone is a stand-alone voice communications system for use within a building or small collection of buildings, functioning independently of the public telephone network. Intercoms are generally mounted permanently in buildings and vehicles. Intercoms can incorporate connections to public address loudspeaker systems, walkie talkies, telephones, and to other intercom systems. Some intercom systems incorporate control of devices such as signal lights and door latches. There are simple house intercoms and intercoms developed for collective apartments. Some are equipped with video, and its wiring (electrical installation), can be connected to the outside with few pairs (4-6 pairs) while controlling an electric strike. The last generations are even compatible with computers and some models include TCP/IP.
Card Reader Access
Access control card readers are used in physical security systems to read a credential that allows access through access control points, typically a locked door. An access control reader can be a magnetic stripe reader, a bar code reader, a proximity reader, a smart card reader, or a biometric reader. Access control readers are classified by functions they are able to perform and by identification technology.
Eye Reader Access
Ocular based biometric technology that uses the unique patterns on a person’s retina blood vessels and is often confused with iris recognition. Iris recognition uses video camera technology with subtle near infrared illumination to acquire images of the detail-rich, intricate structures of the iris which are visible externally. Digital templates encoded from these patterns by mathematical and statistical algorithms allow the identification of an individual or someone pretending to be that individual. Databases of enrolled templates are searched by matcher engines at speeds measured in the millions of templates per second per (single-core) CPU, and with remarkably low false match rates.
The New Generation of Smart Devices in Biometrics for Access Control enhances building security, internal communications, and employee management, at a significantly lower total cost of ownership than previous biometric systems for physical access control. Whether being used to access a building, secure restricted locations within, or for time and attendance management, biometric authentication technology has come a long way. Today, biometric security devices do much more than authentication: they also provide the right level of security, at the exact places needed, and are able to adjust dynamically the level of authentication necessary for ever-changing threat levels. These capabilities only increase in importance as modern physical access control systems also begin to converge with other building management and communication devices. To manage employees, visitors, and contractors better, and protect important areas — executive floors, data centers, and research labs more companies are deploying physical security systems, video surveillance cameras, and time and attendance systems.
Digital keyless entry systems are designed for single entry point access control applications. These keypads are typically used to activate automatic gates, electric door strikes, magnetic door locks, and solenoid locks. Access is granted to authorized personnel by entering an assigned code on the keypad.
