Understanding Security Components

Many house owners rely on home security systems to detect and warn them of intruders sneaking into their properties. These security devices undergo multiple upgrades to improve the ways sensors and alarms can protect a family or home. In most situations, homeowners rely on the security companies to provide and install the gadgets. Still, having a brief understanding of how the security alarms work can provide one an extra sense of safety.

Most security systems have three components: locks, sensors and alarms. Locks provide the first safety measure since the device keeps the doors shut and secure. The latest state-of-the-art security locks come with keypads or scanners, opening only with the proper PIN, password or biometric features.

Sensor and alarm systems are the most common security devices. Sensors detect forced entry, and unusual or unrecognizable movement and trigger the alarms. Motion sensors or detectors also pinpoint the location of the intruder for quick apprehension. Alarms, in turn, are warning devices that alert people in case of security breaches. They catch attention through sirens and bright lights, or even trigger public security systems for quick action.

Window or door sensors can also be connected to in-house motion detectors and CCTV cameras. When the sensors are tripped, they trigger the motion detectors to be on guard for movement. The motion detectors manipulate the CCTV camera to point it directly to the location where movement was detected, enabling the camera to catch a visual of the intruder.
