Protection That Fits Every Type of Home

Every home is different, but the need for reliable protection is the same. Our residential security systems combine motion detectors, glass break sensors, and door and window contacts to keep your family safe around the clock. Whether you live in a condo, townhouse, or detached home, we provide complete coverage designed to fit your lifestyle and give you peace of mind.

Pet-friendly technology ensures false alarms are minimized while your family stays protected around the clock.

Glass Break Sensors for Doors and Windows

Glass break sensors add an extra layer of protection for vulnerable entry points like patio doors, basements, or large windows. If someone tries to smash the glass, the sensor triggers immediately and connects to our monitoring station. It’s fast, reliable security that protects your home before an intruder gets inside.

Door and Window Contacts for Every Entry Point

Simple but powerful, door and window contacts notify you whenever an entry point is opened. From front doors to garage entrances, you’ll always know who’s coming and going. They’re ideal for both security and peace of mind, alerting you if kids arrive home or if someone tries to force entry.
