Door and Window Sensors for Home Security
Doors and windows are common access points, so entry sensors are a core part of many home alarm systems.
How Entry Sensors Work
Most sensors use two small components that sit close together when the door or window is closed. When the contact separates, the system can detect the change.
Where to Place Entry Sensors
Common locations include:
- Front door
- Back door
- Garage entry door
- Ground-floor windows
- Patio doors
- Side entrances
Why Entry Sensors Matter
They provide simple coverage for the areas people use most frequently to enter a property.
Best Practice
Prioritize the most accessible entry points before adding sensors to less-used areas.
Motion Sensors and Indoor Security
Motion sensors add another layer of coverage by detecting movement within selected indoor areas.
Common Placement Areas
- Hallways
- Living rooms
- Entry areas
- Staircases
- Basement access points
Benefits of Motion Detection
- Covers larger interior spaces
- Complements door and window sensors
- Helps detect movement after an entry point is crossed
- Can support smart alerts on compatible systems
