Security alarm systems are sets of interlinked electrical devices that are installed in commercial, industrial, or residential premises as a way of protecting life and property from unauthorized intrusions.
Commonly installed against burglary, they send out sirens and other alerting signals whenever a security threat is detected by sensors such as sound and motion detectors as well as camouflaged wall- mounted cameras.
A growing demand
These models are gaining widespread usage following the rising incidents of burglaries and related crimes in many places around the world. Notably, most burglaries also occur in broad daylight.
Following such disturbing trends, it is understandable how most homeowners came to consider installing burglar alarm systems in their houses as a paramount necessity. As if to affirm this notion, there is sufficient evidence that they do, in fact, help significantly in the prevention of burglaries and in the apprehension of burglars.
Types of security alarm systems
Different models came in many shapes and sizes. There are different types, each developed for a specific purpose, coverage, and budget. There are hardwired models as well as sophisticated wireless models. There are also monitored and unmonitored types. There are also inexpensive models that consumers can readily install on their own. On the other hand, there are burglar alarm systems that require trained security technicians to install, operate, and monitor. These types generally include monthly service fees for a 24-7 security support.
When intending to purchase a security alarm system, homeowners should consult security professionals as well as conduct a preliminary inspection of their residences and their immediate vicinity. These will help prevent unnecessary expenses and allow the identification of the best option based on the homeowner’s budget and security requirements.
How these alarm systems work?
Security alarm systems work differently depending on the type. In wireless alarm systems, small transmitters are used to communicate with different components without the use of cables. Self-powered sensors with transmitters are mounted on all hot spots such as doors, windows and hallways.
When unauthorized entry is detected the transmitters send a signal to the control panel which then triggers a siren to notify occupants of the building and other people in the vicinity that an unauthorized entry has occurred.
On the other hand, hardwired security models are mounted and wired directly on walls. These types of alarm systems are more commonly used as they are less expensive than the more advanced wireless models. System components, including wiring paraphernalia are generally camouflaged or concealed to prevent burglars from detecting them and disabling the system by cutting the electrical connections or destroying the sensors.
The one possible advantage of hardwired security alarm systems over their wireless counterparts is that they are less likely to suffer from electrical interferences or noises, which often result to false alarms, or temporary malfunctions in wireless models.
