Security alarm systems on Long Island come in all shapes and sizes, but they usually combine motion sensors with entry contacts (like doors and windows) connected to an alarm device that’s controlled by a keypad. Once the system is armed, if the sensors and contacts are disrupted, it will activate the alarm system. The same thing happens when a motion sensor is triggered. Here’s how each one works:
- Contacts – These simple little devices are installed at an entry point, and when they’re interrupted, the alarm goes off. Whether you’re powering a flashlight or a hair dryer, electricity flows only when it has a path between two opposite charges. Close the circuit and you turn off the power — or in this case, sound the alarm. The alarm system activates when the switch is interrupted by an intrusion – like when a door or window opens.
- Motion Sensors – Contacts are great for protecting the perimeter of a house, but they don’t work so well inside a building. Motion sensors, including radar-based sensors, photo sensors and the more sophisticated passive infrared (PIR) motion detectors are all used to detect motion within a building. Essentially, they work when a person disturbs the reflection pattern, and the detector sends an alarm signal to the control box.
The best alarm systems on Long Island use both these methods to detect an unauthorized intruder. If you don’t disarm the system by entering the right code in the keypad, it will notify the monitoring center, then notify both you and the local authorities on Long Island. More advanced systems can detect events like fire and flood detection, but the most basic systems are based on contacts and motion sensors.
Whatever kind of security system you use, make sure to find a local, reputable home security alarm company on Long Island that works closely with you to address every detail of your home security system.
