How Home Security Alarm Monitoring Works

The home security industry is in a constant battle to keep ahead of the methodology of burglars. It is driven by the need of people to guarantee the safety of their homes, even when they are not present to watch them. Home security monitoring is a growing technology to help people gain that security.

The basic tools of safe home security monitoring are sensors to detect inappropriate change in the premises, such as from heat, gas or fumes, or motion. Signals from these sensors have to be transmitted as warnings either to police, emergency respondents or the clients themselves.

The installation of a security monitoring system can be very elaborate. The sensors have to be carefully and strategically placed to maximize the chance of catching an intrusion, a fire, or emergency chemical leak. It has to set up so that it can’t easily be turned off by an intruder, but can be disabled as needed by the users when they are present. Usually the system works with secure codes or secret transmissions so that the users themselves don’t trigger the alarm. Furthermore, the unit has to be set up in such a way that it is powered securely, independently from the electrical fuse box in the building. This assures that it can’t be easily disabled by an intruder.

Warning devices like smoke detectors consist of sensitive light meters paired with light sources. When smoke comes between the light meter sensor and the light source, the device interprets this change as possible fire and generates an alarm signal.

Chemical detectors are devices that analyze the air and respond to the presence of particular types of molecules. They generate an alarm signal when these dangerous situations are detected.

Motion detectors may work by picking up changes in the standing pattern of infra-red light in a room. They may also detect vibrations in the floor or walls of a house. Motion detectors then generate an alarm signal.

Small cameras are probably the most elaborate sensors. These are basically tiny web-cams that send digital images to a computer circuit for storage. Security cameras can be made pin-hole size and can be easily hidden or disguised. They are capable of transmitting wide angle images of good quality wirelessly or via hidden cables. The images can be kept in memory for later viewing and can be viewed directly.

Sometimes the signals from sensors are simply translated into alarms or warnings directly to the intruder or used to set off recorded voices, dog barks or alarm lights. In more elaborate security monitoring systems, the sensor signals are marked with location information and will be transmitted to monitoring centers with human operators. The operators interpret the signals and can respond by posting messages or alerting emergency personnel.

With today’s technology, security monitoring systems can be controlled and viewed through internet sites set up by the security provider. These internet sites can be addressed on smart cell phones, tablets or other computer systems anywhere in the world. Each system subscriber would be assigned their own secure web site address so that only they would be able to receive data and images from their sensors and any transmissions from the service provider.
