best security systems for business

The components I will address in this discussion are building security, grounds security, access control systems, perimeter security, and information systems and technology security. Physical Security: Brief OverviewIn the assessment of security vulnerabilities, physical security is generally regarded a critical issue. This is particularly the case given that it is the said physical security that presents the most serious obstacle to an attacker seeking to execute a break in. In that regard therefore, the various components of physical security, some of which are discussed in significant detail in this text, should seek to secure people and organizational assets from intruders. For this reason, physical security could…… When considering their security needs, businesses will be faced with whether to develop an in house, proprietary team or to outsource their security to a contractor. There are significant differences between contract security services and proprietary security, as well as costs and benefits associated with each.

Sensors are the most vital part of the system; they act like the eyes and ears of a home alarm system by monitoring break in points and interior areas. The typical sensors, which are usually two magnets, are generally installed on doors and windows such that one magnet is connected to the door or window and the other is connected to the door or window frame. When the door or window is opened, one magnet is removed from the surrounding area of the other and the sensor registers that the door has been opened. More advanced home alarm systems may also contain vibration sensors to detect when glass has been broken by measuring the vibrations caused by the breakage. Also, many systems use motion sensors that compute the proximity of a room’s walls by producing infrared beams and measuring the time required for them to bounce back; if a beam comes back sooner than expected, it likely bounced off of a person and the sensor registers motion. The control center keeps track of the status of the sensors and reports activity through LCD displays and other output devices.
