Home security equipment used to be a luxury reserved for the rich and famous; but these days, countless companies provide average homeowners with reliable security systems. While the equipment can vary depending on the company or manufacturer, all systems are comprised of the same basic equipment.
1. Keypad: This is a small box with a numbered faceplate that performs two main functions: to initiate security commands, and to display the status of the security system. Keypads include an alphanumeric keypad and an LED display. Homeowners enter a predetermined code to activate the alarm when they are leaving the property, and to deactivate it when they return home.
Many keypads include a panic switch to alert the system immediately in case of emergency, as well as a bypass function that lets the homeowner customize the system to bypass areas where family members may be present. The LED display shows the status of the alarm system; that is, whether or not the system is active.
2. Sensors: These protect the perimeter of the home, as well as open spaces inside. Most common sensors used in home security equipment are window vibration detectors, magnetic door or window switches and acoustical detectors. These sensors are installed on doors and windows to prevent intruders from entering the house. Space protection sensors can also be installed to detect intruders within hallways and interior rooms.
