These are typically used to protect rooms containing valuables, as well as areas less frequented in larger homes. Motion Sensors:В These security components, when armed, protect a given space by creating an invisible zoneВ that cannot be breached without sounding an alarm. A high-decibel alarm is sounded and in most instances the alarm monitoring company is automatically notified. Should a monitored door or window suddenly be opened, the security circuit is broken and the control panel interprets this as a breach of a secured zone. When the security system is armed at the control panel, these sensors communicate with it by reporting that the point of entry is secure. When a door or window is closed, the two parts of the sensor are joined together, creating a security circuit. One part of the device is installed on the door or window and the other on the door frame or window sill. They typically feature a touchpad for easy programming and interaction, is where pass codes are entered to arm and disarm the system, can work on voice commands, and can be programmed to work with wireless remote controls called key fobs.Дoor and Window Sensors: Door and window sensorsВ are comprised of two parts installed adjacent to each other. Open spaces inside of homes can be secured with motion sensors.Д¬ontrol Panel:В The control panel is the computer that arms and disarms the security systems, communicates with each installed component, sounds the alarm when a security zone is breached, and communicates with an alarm monitoring company. The sensors are typically placed in doors that lead to and from a house as well as easily accessible windows, particularly any that open, especially those at ground level. Home security systems work on the simple concept of securing entry points into a home with sensors that communicate with a control panel or command center installed in a convenient location somewhere in the home.
