Sam 488 unit 5 - Assignment Example As argued by Fay (2011), the mechanism that defines the user access control is based on the elements that are necessary for an effective visitor access control system. Some of these elements include the access control directory, specific users, specific locations, and AICs principles. It is also important to note that these elements directly operate under the access control principles. In this case, the authentication provided by the user in the bind operation, when the security server receives a request that is defined in the server, allows or deny access to directory information. The Selection, purchase, installation, and operation of security devices that promote restricted security for safety are very critical to the security system. In this case, the purchase and installation of the locking devices for security purposes also depends on a number of factors. Some of these factors include the security cameras to be used, type of the locking devices, card readers, and a proper response protocol (Fay, 2011). Motion detectors are employed to successfully guard an in-house perimeter that has proven highly unpredictable for a circuit alarms. Using the reflective effects of certain waves, the motion detector is a device that seeks a disturbance situation in the room when an intruder enters the parameter, and the reflection pattern is disturbed. The sensor sends a signal, when this happens, and the door opens to send an alarm signal ultimately (Fay, 2011). The ultrasonic motion detectors work or s employed efficiently using the sound waves. When the movements disrupt the air and the sound waves, the sensors sound alerts of intrusion. Automatically, the waves strike objects within the field of detection and as long as there is no movement, the waves are not disrupted. Otherwise, the sound waves become interrupted and are reflected back to the receiver of the security system. The principle
