INTRUDER ALARM SYSTEMS
A security alarm is a system designed to detect intrusion – unauthorized entry – into a building or other area such as a home or school. Security alarms are used in residential, commercial, industrial, and military properties for protection against burglary (theft) or property damage, as well as personal protection against intruders.
Security alarms in residential areas show a correlation with decreased theft. Car alarms likewise help protect vehicles and their contents. Prisons also use security systems for control of inmates.
Some alarm systems serve a single purpose of burglary protection; combination systems provide both fire and intrusion protection. Intrusion alarm systems may also be combined with closed-circuit television surveillance (CCTV) systems to automatically record the activities of intruders, and may interface to access control systems for electrically locked doors.
Systems range from small, self-contained noisemakers, to complicated, multirally systems with computer monitoring and control. It may even include two-way voice which allows communication between the panel and Monitoring station.
ACCESS CONTROL SYSTEMS
The act of accessing may mean consuming, entering, or using. Permission to access a resource is called authorization.
Typically, a fire extinguisher consists of a hand-held cylindrical pressure vessel containing an agent which can be discharged to extinguish a fire. Fire extinguishers manufactured with non-cylindrical pressure vessels also exist but are less common.
Closed-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 (P2MP), or mesh wired or 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, stores, and other areas where security is needed. Though videotelephony is seldom called ‘CCTV’ one exception is the use of video in distance education, where it is an important tool.
Surveillance of the public using CCTV is 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, often used in law enforcement, with cameras located on a police officer’s chest or head. Video surveillance has generated significant debate about balancing its use with individuals’ right to privacy even when in public.
SMART PROPERTY SYSTEMS
Property Management Systems(PMS) or Hotel Operating System(HOS), under business terms may be used in real estate, manufacturing, logistics, intellectual property, government or hospitality accommodation management.
They are computerized systems that facilitate the management of properties, personal property, equipment, including maintenance, legalities and personnel all through a single piece of software.
They replaced old-fashioned, paper-based methods that tended to be both cumbersome and inefficient. They are often deployed as client/server configurations. Today, most next generation property management systems favour a software-as-a-service (SaaS) model sustained by web and cloud technologies.
