CCTV / Closed circuit Television
Closed-circuit television (CCTV) 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. CCTV is often used for surveillance in areas that may need monitoring such as banks, casinos, airports, military installations, and convenience stores. It is also an important tool for distance education.[1][2]
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-based CCTV 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 the UK, where there are reportedly more cameras per person than in any other country in the world.[3] There and elsewhere, its increasing use has triggered a debate about security versus privacy.
Closed-circuit digital photography (CCDP)
A development in the world of CCTV (October 2005) is in the use of megapixel digital still cameras that can take 1600 x 1200 pixel resolution images of the camera scene either on a time lapse or motion detection basis. Images taken with a digital still camera have higher resolution than those taken with a typical video camera. Relatively low-cost digital still cameras can be used for CCTV purposes, using CCDP software that controls the camera from the PC.
Images of the camera scene are transferred automatically to a computer every few seconds. Images may be monitored remotely if the computer is connected to a network.
Combinations of PIR activated floodlights with 1.3Mpix and better digital cameras are now appearing. They save the images to a flash memory card which is inserted into a slot on the device. The flash card can be removed for viewing on a computer if ever an incident happens. They are not intended for live viewing, but are a very simple and cheap "install and forget" approach to this issue.
Closed-circuit digital photography (CCDP) is more suited for capturing and saving recorded photographs, whereas closed-circuit television (CCTV) is more suitable for live monitoring purpose
Why manage keys electronically?
The justification for electronic key management is often based on the idea that security directors and managers, as well as facility professionals, want to control and manage the entry and use of rooms and assets within a facility, or institution. Today's modern access control systems rely to a large extent upon access card (mag stripes, proximity cards, smart cards, etc.) but they often do not cover a certain number of assets, doors, and rooms, which are still accessed by traditional keys. These tradition mechanical keys must be controlled and managed in order to assure a safe and secure system.
Sometimes access control companies will provide an alternative to the standard "arm every door with card readers" approach by suggesting that the client use a single key management system to protect a large number of seldom used doors, as a value added alternative.
Cost considerations
An additional basis for utilizing a good key management system is the cost consideration. Lost keys cost organizations, institutions, and government more than $35 billion per year according to some studies. The cost of lost or misplaced keys results from time spent searching for keys and/or their holders, as well as the costs of replacing locks, cylinders, and keys, not to mention staff time and management time resolving lost key issues.
Who uses electronic key management?
Users of good electronic key management systems include property management companies, government, auto dealerships, prisons and institutions, colleges/universities, assisted living centers, casinos, and any place where access control is a consideration.
Modern electronic key management systems use a variety of technologies including Microchip and RFID for ease of identifying keys
