A good home security system is not just a way to deter intruders, it can also protect the occupants from health hazards by detecting gas leaks, carbon monoxide poisoning, smoke, fire, and water damage. So, getting a home alarm system is not a necessary expense but a long-term investment that enhances the safety of the home, occupants, and valuable belongings. It also gives one some peace of mind by making the home safer.  Reasons to get a home alarm system A home alarm system is one of those essential things to consider for preventing events like theft and break-ins. It also serves the following purposes: 1. Protection from intrusion Alarm systems can detect break-ins or intrusions using a sensor network. Motion sensors of the system, installed inside or outside the property, can detect movement. Also, switches mounted on a window alarm trigger an alarm when someone opens it. If the system has a glass break detector, it has an audio sensor that can detect the sound of glass breaking. Some alarm systems come with shock sensors that can detect break-ins through the wall. Based on the detection, the system sends alerts. When the master control panel, or base station, gets an alarm and registers an event, a signal is sent to the monitoring agency.
