The basic layer of Security is mechanical and includes gates, doors, and locks. Key control of the locks becomes a problem with large user populations and any user turnover. Keys quickly become unmanageable forcing the adoption of electronic access control. Electronic access control easily manages large user populations, controlling for user lifecycles times, dates, and individual access points. Security Video Door Phone with Camera is your good choose now.
An additional sub-layer of mechanical/electronic access control protection is reached by integrating a key management (physical key management) system to manage the possession and usage of mechanical keys to locks or property within a building or campus.
The third layer is intrusion detection systems or alarms. Intrusion detection monitors for attacks. It is less a preventative measure and more of a response measure, although some would argue that it is a deterrent. Intrusion detection has a high incidence of false alarms. In many jurisdictions, law enforcement will not respond to alarms from intrusion detection systems.
A mobile phone jammer is an instrument used to prevent cellular phones from receiving signals from or transmitting signals to base stations. When used, the jammer effectively disables cellular phones. These devices can be used in practically any location, but are found primarily in places where a phone call would be particularly disruptive because silence is expected.
