Home Security by bassburglaralarms.com - House Alarm System

A basic monitored house alarm system includes:
Motion detectors. Also known as passive infrared (PIR) detectors, these devices sensing changes in infrared energy levels when an intruder is present, even if no break-in is detected. They are typically installed indoors at walls, doors, windows, and air ducts.
Door and window contacts. These magnetic devices are placed along door jams and window frames and trigger the alarm system when opened.
Glassbreak sensors. Also referred to as "audio discrimination", these sensors convert the acoustic shock waves of glass breaking into an electrical signal and set off the system.
Sirens. Loud bells, horns, and/or strobe lights can be installed inside and outside your home to draw immediate attention to the intrusion.
