Remote Guarding
Remote guarding is a proactive security system combining CCTV video cameras, video analytics Video content analysis or video content analytics (VCA), also known as video analysis or video analytics (VA), is the capability of automatically analyzing video to detect and determine temporal and spatial events. This technical capability is used ..., alarms, monitoring centers and security agents. Potential threats are first spotted by cameras and analyzed in real-time by software algorithms based on predefined criteria. Once an event has been identified by the software, a security officer located in a remote center is then alerted to analyze the threat and take appropriate action immediately to prevent or minimize damage from occurring. These actions can include a verbal warning to the perpetrator via two-way radio from the center or reporting the event to local law enforcement. Remote guarding adds a layer of human verification to automated security systems that results in reducing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Closed-circuit Television Camera
A closed-circuit television camera can produce images or recordings for surveillance or other private purposes. Cameras can be either video cameras, or digital stills cameras. Walter Bruch was the inventor of the CCTV camera. The main purpose of a CCTV camera is to capture light and convert it into a video signal. Underpinning a CCTV camera is a CCD sensor (charge-coupled device). The CCD converts light into an electrical signal and then signal processing converts this electrical signal into a video signal that can be recorded or displayed on the screen. Video cameras Video cameras are either analogue or digital, which means that they work on the basis of sending analogue or digital signals to a storage device such as a video tape recorder or desktop computer or laptop computer. Analogue These cameras can record straight to a video tape recorder which can record analogue signals as pictures. If the analogue signals are recorded to tape, then the tape must run at a very slo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alarm Monitoring Center
An alarm monitoring center or central monitoring station (also known as "CMS" or wholesale central station) is a company that provides services to monitor burglar, fire and residential alarm systems. The Central Monitoring Station may also provide watchman and supervisory services. "It functions as a support system for critical event management devices, such as: security alarm panels, gas and temperature gauges, PERS devices, crash detection devices, integrated video systems, and even mobile applications." Central monitoring stations use special telephone and mobile lines, radio channels, computers, software and trained staff to monitor their customers' security systems and call the appropriate authorities in the event an alarm signal is received. Typically, there is a monthly fee for services rendered. Because quality and experience can vary greatly among alarm companies, prospective customers are well advised to do their own research before making a final choice. Not all alarm co ...

Security Guard
A security guard (also known as a security inspector, security officer, or protective agent) is a person employed by a government or private party to protect the employing party's assets (property, people, equipment, money, etc.) from a variety of hazards (such as criminal activity, waste, damaged property, unsafe worker behavior, etc.) by enforcing preventative measures. Security guards do this by maintaining a high-visibility presence to deter illegal and inappropriate actions, looking (either directly, through patrols, or indirectly, by monitoring alarm, alarm systems or closed-circuit television, video surveillance cameras) for signs of crime or other hazards (such as a fire), taking action to minimize damage (such as warning and escorting trespassers off property), and reporting any incidents to their clients and emergency services (such as the police or paramedics), as appropriate. Security officers are generally uniformed to represent their lawful authority to protect priv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alphabetical musical instruments Etymology The word ''alarm'' comes from the Old French ''a l'arme'' meaning "to the arms", or "to the weapons", telling armed men to pick up their weapons and get ready for action because an enemy may have suddenly appeared. The word ''alarum'' is an archaic form of ''alarm''. It was sometimes used as a call to arms in the stage directions of Elizabethan dramas. The term comes from the Italian ''all'armi'' and appears 89 times in Shakespeare's first folio. Often explained as the off-stage sounds of conflict or disturbance, recent research suggests a bell or drum may have been used to rouse soldiers from sleep. History and development Early alarm devices were often bells, drums, other musical instruments, or any items which made unusual loud noises that attracted the attention o ...
