How Home Security Systems Work?
Home security involves both people’s personal security practices and the security hardware installed in a home. Home security hardware includes deadbolts, locks, windows, surveillance cameras, lighting, and motion detectors. Many home security experts believe that the best way to protect a home from criminals is to have both an interior and exterior home security system. However, many homeowners do not have this option because they fear installing invasive devices in their homes. There are a number of factors, however, that can make home security systems less effective or simply unnecessary.
First, many homeowners mistakenly install too many security items around their homes. For example, they place surveillance cameras in key areas such as the front door and backyard but install faulty motion sensors outside of these areas. When this happens, false alarms are often triggered which could cause an unnecessary trip to the phone or Internet to contact a neighbor.
Another factor that makes a home security system ineffective is when the signal from motion sensors is not strong enough to send an alert to the proper alarm center. Motion sensor technology was developed specifically to detect body heat, making it perfect for identifying unwanted guests. However, some homeowners continue to place their motion sensitive cameras outside of the house. The problem with this is that the movement of a person near a motion sensor is not always guaranteed an alert to the home security center. As a result, a burglar or other intruder may not trigger the alarm.
Even when motion sensors are properly installed, homeowners may find that their security system is still insufficient. In most cases, security cameras are only effective if they receive a signal from at least one of the three wires placed in their perimeter. If only one wire is functioning, the camera will not function. Most security companies provide installation services that include laying down new wiring or installing updated cameras that can recognize heat signatures. This ensures that all three wires will be connected and functioning correctly whenever the camera is activated.
Home Security companies have also invested in smart home automation technology. Homeowners can use home automation systems such as their built-in DVR’s to monitor their property. When an intruder triggers an alarm, the DVR records the scene for further review by the homeowner. Some systems also allow the user to disarm the home alarm system remotely, without having to disarm the cameras or disarm the alarms individually.
Other advanced features that have been added to home security systems include touch-screen control panels. These control panels make it possible to program light switches, thermostat adjustments, TV volume controls and other similar items. This allows users to set off lights when no one is home, adjust TV volume levels before leaving home, turn on and off the vacuum and other items throughout the house using touch-screens. The touch-screen controls can be programmed with codes that allow the household to gain access to everything if they should need access to certain areas of the house while the owner is away. Touch screen control panels also allow users to disarm the home alarm system by pressing a designated number on the control panel. This allows the homeowner to arm the system before leaving home or while they are away from the house.
Sophisticated motion sensors are also available. Motion sensor devices are typically installed inside of windows and doors. When a person enters a room, a microprocessor in the control panel detects movement in the room and activates the alarm. If no motion is detected, the system is set to alert the local police department. The installation process requires window sensors to be installed on each window in the home, so when they are installed, they can sense movement in the room.

High-decibel alarm systems are also available for those homeowners who wish to install a security system in the exterior of their home. Exterior sensors are designed to detect motion and high-frequency sound waves. When an intruder passes within a certain distance of the control panel, the sensors will detect the sound wave and trigger the high-decibel alarm. Motion sensors are much more expensive than the window sensors, but are more likely to deter criminals because of the high-decibel sound they generate. Home Security systems can significantly reduce your risk of becoming a victim.
