What devices detect business or home intruders and set off a burglar alarm?
There are various devices used in home security systems to detect intruders and trigger a burglar alarm.
Here are some common types of devices:
Door and window sensors: These sensors are typically composed of two parts—one attached to the door or window frame and the other to the moving part (such as the door or window itself). The sensor triggers the alarm when the connection between the two components is interrupted, such as when a door or window is opened.
Motion sensors: Motion sensors detect movement within a specific area. They use various technologies, including infrared (PIR), microwave, or dual technology (combining PIR and microwave), to detect changes in heat or movement. When an intruder crosses the sensor's detection field, it triggers the alarm.
These motion sensors are usually pet friendly, but if you have a larger pet, such as a dog, you may be unable to place them in your business or home.
Additionally, if you have a large pet and still want motion sensors, speak to your alarm company. In that case, they may make the alarm work by placing the sensors where your pet does not wander or program your alarm with an additional step where you can activate that part of the alarm when everyone is out of the business or house.
Glass break detectors: These devices are designed to recognize the sound frequencies and patterns of breaking glass. When the glass break sensor picks up these specific sounds, it sends a signal to activate the alarm.
Pressure mats: Pressure mats are often placed under carpets or rugs near entry points. They are triggered when someone steps on them, causing a change in pressure, and the alarm is activated.
Vibration sensors: Vibration sensors are usually attached to windows, doors, or other vulnerable points. They detect vibrations caused by an attempted forced entry, such as when an intruder tries to break a window or kick down a door.
Security cameras: While security cameras primarily serve the purpose of surveillance and recording, they can also be integrated into alarm systems. Combined with video analytics, they can detect movement or unusual activity and trigger an alarm.
Panic buttons: Panic buttons can be manually activated to trigger an immediate alarm. They are typically installed in discreet locations and can be handheld or wall-mounted.
These devices work in tandem with a control panel, which serves as the central hub of the business or home security system. When a sensor is triggered, it sends a signal to the control panel, which activates the alarm siren and may also communicate with a monitoring center or send alerts to designated contacts.
It's important to note that the specific devices used in a business or home burglar alarm system can vary based on the system's design, features, and preferences of the company or homeowner.
