Alarm systems
Always choose an alarm system that is installed and supported by a reputable security company. A standard alarm system uses motion sensors that keep watch over doors, windows and indoor areas, but don’t forget about the garage. With most systems, users can set the sensors to inactive when they are at home, while activating the exterior sensors which are the magnetic contact points that are installed in doors and windows. Maintain your alarm system by cleaning the infrared sensors with a damp cloth on a regular basis as dust and grime can make the system less effective.
Test your alarm on a regular basis.
