Home Security System Equipment
Home Security Systems
Many people don’t fully understand how complex a security system‘s components are. In order for a system to be effective, all of these components have to be properly installed. The most common components of a security system are as follows:
The control panel of a security system could essentially be called the “brain” of the system. The control panel receives and analyzes signals from all of the devices in your home, converting these signals into “alerts” if it detects a security breach.
Control Panel / Keypad
Most home security systems also have a keypad, which is usually located on the control panel. Through the keypad, a user has complete control over the system status, alarms, monitoring and other features. The keypad is also usually where the system is armed or disarmed, except if a user has a remote arming device.
Some security systems have a feature that allows them to be armed or disarmed from a location outside of the home. This is usually in the form of a small remote, which is able to send a signal to the control panel to arm or disarm the system. This remote is useful for people who wish to have control of their security system while still outside of their home.
A burglar alarm is included in many home security systems. The alarm is usually triggered when the control panel detects an emergency through activation of any of the security devices currently monitoring a home. Many alarms are rated by “Decibel Level”, which is basically the level of sound emitted by the alarm.
Motion detectors are usually a fairly standard component in many home security systems. A motion detector is able to detect movement in a designated area, usually by using infrared signals to analyze heat sources. The type of infrared used in motion detectors is called “Passive Infrared” Detection, also called PIR. When it detects a sudden change in the average heat of an area (sometimes to a specific degree) it alerts the security system control panel.
A glass break sensor is able to detect if the glass in a door or window has been broken. It monitors for the specific frequency of sound that signals that glass has been broken. If it detects that a door or window has been broken, it will alert the control panel, which often triggers the burglar alarm.
For advanced home security, many systems now offer pressure sensors to help detect intrusions. These sensors may be small sensor “blocks”, or may be designed to operate in a “mat” that is triggered when it detects weight.
Surveillance cameras are another important part of many home security systems. Some surveillance cameras are motion-activated, while others are designed to simply broadcast images. There are also cameras that are able to operate in low-light conditions, often by using infrared signals.
Carbon Monoxide Sensors
A carbon monoxide sensor is most effectively used when placed in an area of the home where your family gathers frequently. A carbon monoxide sensor is triggered when unsafe levels of carbon monoxide are discovered in your home. This alerts the control panel, which may then trigger an audible alarm.
Door and window sensors are also sometimes called “contact point” sensors. These sensors are able to detect if a door or window in your home has been opened. Two “contact points” are placed on and near an entry point, which have a magnetic connection between them. When the door or window is opened, the magnetic connection is broken, which triggers the security system.
Many security systems also have a combination smoke and heat sensor which helps to protect a home against fire. If the sensors detect abnormal levels of heat, or smoke, the system is triggered to sound an alarm.
