Alarm system installation in Thornhill
Thornhill’s larger family homes need more than a keypad and two door contacts. Knightwatch designs each system on site around the way the house is actually used, then installs it with our own technicians.
Designed for larger homes
- Walk-out basements and patio doors: contacts plus glass-break detection on large glass.
- Attached garages: the garage-to-house door and the overhead door, so the garage isn’t a way in.
- Two-storey layouts: a “stay” mode that arms the main floor and basement while the family sleeps upstairs.
- Keypads where you come and go: usually the garage entrance, plus phone arming from the app.
Wired, wireless or both
Homes with existing alarm wiring can reuse it for a hardwired system; finished homes without wiring suit wireless devices. Many systems combine both. Read hardwired vs wireless alarms.
Life-safety and away-from-home protection
Add monitored smoke, CO and flood detection so the monitoring station responds even when you’re away, and AI security cameras that warn intruders off the driveway and backyard.
