4das Door Access Control Systems is a matter of who, where, and when. An access control system determines who is allowed to enter or exit, where they are allowed to exit or enter, and when they are allowed to enter or exit. This was partially done through keys and locks. When a door is locked only someone with a key can enter through the door depending on how the lock is set up.

Mechanical locks and keys do not limit the key holder to specific times or dates. Mechanical locks and keys do not provide records of the key used on any specific door and the keys can be easily copied or transferred to an unauthorized person. When a mechanical key is lost or the key holder is no longer authorized to use the protected area, the locks must be re-keyed. Instead of Mechanical Locks and Keys.

Electronic door access control uses computers to solve the limitations of mechanical locks and keys. A wide range of methods can be used to replace mechanical keys. Some kind of remote telemetry unit at each door location grants access based on the credential presented such as; password entered on a keypad, a swipe card used with a proximity sensor, or even biometrics. The decision can be made locally by the door unit, remotely by a central management system or cooperatively by sharing login profiles and access requests. When access is granted, the door is unlocked for a set time and the event is logged.

When access is refused, the door remains locked and the attempted access is recorded. The system will also monitor the door and alarm if the door is forced open or held open too long after being unlocked.

3cctvClosed-circuit television (CCTV), also known as video surveillance, is the use of video cameras to transmit a signal to a specific place, on a limited set of monitors. It differs from broadcast television in that the signal is not openly transmitted, though it may employ point to point (P2P), point to multipoint, or mesh wireless links. Though almost all video cameras fit this definition, the term is most often applied to those used for surveillance in areas that may need monitoring such as banks, casinos, airports, military installations, and convenience stores. Videotelephony is seldom called "CCTV" but the use of video in distance education, where it is an important tool, is often so called.

In industrial plants, CCTV equipment may be used to observe parts of a process from a central control room, for example when the environment is not suitable for humans. CCTV systems may operate continuously or only as required to monitor a particular event. A more advanced form of CCTV, utilizing digital video recorders (DVRs), provides recording for possibly many years, with a variety of quality and performance options and extra features (such as motion detection and email alerts). More recently, decentralized IP cameras, some equipped with megapixel sensors, support recording directly to network-attached storage devices, or internal flash for completely stand-alone operation. Surveillance of the public using CCTV is particularly common in many areas around the world. In recent years, the use of body worn video cameras has been introduced as a new form of surveillance.

The first CCTV system was installed by Siemens AG at Test Stand VII in Peenemünde, Germany in 1942, for observing the launch of V-2 rockets.[4] The noted German engineer Walter Bruch was responsible for the technological design and installation of the system.

2ictA local area network may serve as few as two or three users (for example, in a home network) or as many hundreds of users. Ethernet and Wi-Fi are the two most commonly used LAN technologies. Other LAN technologies, including Token Ring, Fiber Distributed Data Interface and ARCNET have lost favor as Ethernet and Wi-Fi speeds have increased.The rise of virtualization has fueled the development of virtual LANs (VLANs) which allows network administrators to logically group network nodes and partition their networks without the need for major infrastructure changes.

Typically, a suite of application programs can be kept on the LAN server. Users who need an application frequently can download it once and then run it from their local device. Users can order printing and other services as needed through applications run on the LAN server. A user can share files with others stored on the LAN server; read and write access is maintained by a network administrator. A LAN server may also be used as a Web server if safeguards are taken to secure internal applications and data from outside access.

In some situations, a wireless LAN, or Wi-Fi, may be preferable to a wired LAN because of its flexibility and cost. Companies are assessing WLANs as a replacement for their wired infrastructures as the number of smartphones, tablets and other mobile devices proliferates.
