JOIN US For several decades, simple locks were used to lock any building. This was followed by brass padlocks with multiple levers and row pin cylinder type locks combined with electronic locking system. For extra safety, many houses are equipped with iron bars for the front and back doors. A peephole with a lens fixed to the front door and a safety chain are also other ways of checking the credentials of people before letting them in. In addition, steel grill doors are much in vogue today.
As the city has grown, residential localities have extended to areas beyond the heart of the City by many kilometers, with a subsequent increase in the chances of burglary.
Security concerns are especially high in places where working couples have to leave their children alone and where elderly people live. Modern technology has come to the fore to address security problems for such buildings. Electronic security systems installed in houses and apartments raise an alarm against possible intrusion. Taking all these factors into consideration, many builders are today increasingly showing interest in installing the same in multistoreyed apartments and other buildings.
How the system works
There are different kinds of electronic security systems with different functions. A simple alarm system against attempt to tamper the door to several hi-tech ones is available in the market.
A video door phone is a system which helps residents identify a visitor through a monitor installed inside the house and communicate without opening the doors. This also has the facility of operating the door by remote control.
Another is the intrusion alarm system. Here, a control panel is installed inside the house. It is fitted with magnetic connector for the door, motion detector, glass breaking detectors and sensors for the windows and other possible accessible places. Any obstruction noticed by the system raise an alarm. This is a useful precautionary device.
Many companies which provide these security systems have a Central Monitoring System. In this warning signals from individual customers are recorded and monitored. In a Central Monitoring system, Infra-red signals are tuned to sense obstacles which are over three and half feet in height and weighs more than 25 kgs in order to restrict false alarms. Even biometric systems are available which can be seen at Tirumala temple where flow of people is very high. In this advanced technology scanning of fingers and retina can also be undertaken.
Different types of signals like fire accident, medical emergency and others can be identified and the police, the doctor or the fire station, depending on the emergency can be contacted. The system provides early warning against attempts of burglary or any emergency like sudden illness; it helps not only to save valuables but also the lives of the inmates of the house. An auto dialing system can also be fixed to these systems where prioritized numbers can alert the police, family members or the doctor. Closed Circuit Television (CCTV) system and an Access control system which restrict the entry of unauthorized people are also available as part of electronic security systems. Some of these systems have other unique feature like identifying pet animals so that false signals are avoided to certain extent. Panic buttons to identify leakage of gas alignment, electric shock circuits are other features provided in these systems. All these systems are safe, easy to operate and cannot be easily tampered with is the opinion of many suppliers who are in the market since a long time. Very recently Japanese have unveiled a security robot that can be operated remotely by cell phone with this a net can be launched to capture an intruder.
