Amongst contributing aspects have been the growth in number of security-sensitive businesses; expansion of new security functions, such as protection of proprietary information; increasing mechanization of sensitive information subject to unique vulnerabilities; improved reporting of crime and consequent wider awareness; and the need in many countries for security against violent demonstrations, bombings, and hijackings. There are many types of security systems, plus scrutinized, unmonitored, electric current and wireless alarm security systems. Many people use monitored security systems. If somebody enters the house, the system sends a signal to the call center via the outdoor phone line, and the call center calls the police. A disadvantage of this system is that burglars can cut the phone wires to disable the system. Also, it may take the call center and police too long to respond Security systems are becoming increasingly automated, particularly in sensing and communicating hazards and vulnerabilities. This situation is true in both crime-related applications, such as intrusion-detection devices, and fire-protection alarm and response extinguishing systems. Developments in decrease and computer electronics are reflected in security equipment that is smaller, more reliable, and more easily installed and maintained. An unmonitored security system sets off a loud alarm on the inside …show more content…
Also, burglars usually try to escape as soon as possible when they encounter this security system. With this system, owners don't have to pay monthly fees for its maintenance, which is an advantage compared to the monitored system. Homeowners can easily install wireless security systems by themselves. Buyers can choose from many types of devices, such as sensors, cameras, beams and motion detectors. A disadvantage of this system is that the owners might have to replace batteries in the devices often, which is expensive. An electric current security system produces a steady electric current to monitor doors and windows in the house, producing a simple beeping sound when doors or windows open. The system's primary disadvantage is that electrical devices inside the house can interfere with the system, reducing its effectiveness. In the ever-changing world of private security, protection officers' roles and responsibilities are quickly adapting to a heightened security environment. Protection officer suppliers are turning to advanced training in everything from the latest high tech system to anti-terrorism for their officers to be ready for whatever corporate and government security assignments come their way. Security Technology & Design magazine recently held a roundtable discussion on the issues facing private security, featuring Ronald R. Rabena, the Midsouth
