Protecting Your Home with Motion Sensors

Smart Detection That Stops Intruders in Their Tracks

Your home may have locks, cameras, and alarms—but if no one sees an intruder approaching, how can you respond in time? That’s where motion sensors come in.

These discreet but powerful devices are the unsung heroes of modern home security. At OnGuard Security Solutions, we help homeowners design customized systems using motion sensors that deliver real-time detection, fast alerts, and reliable peace of mind.

What Are Motion Sensors?

Motion sensors are electronic devices that detect movement within a defined area. When movement is detected, they can:

• Trigger an alarm
• Send a smartphone alert
• Activate lights or cameras
• Notify a 24/7 monitoring center

They can be placed inside or outside your home and work as part of a larger smart security system.

Why Motion Sensors Matter

While door and window sensors alert you when a perimeter is breached, motion sensors fill in the gaps—catching intruders already inside, or moving around your property.

They offer:

• Extended coverage for large or hidden areas
• Faster detection of suspicious activity
• Integration with cameras, lights, and alarms
• Layered security to complement other devices

Types of Motion Sensors for Home Security

1. Passive Infrared (PIR) Sensors

• Detect heat (infrared radiation) from moving bodies
• Most common and cost-effective
• Ideal for indoor use in hallways, living rooms, basements

2. Microwave Sensors

• Emit microwave pulses and detect reflection changes
• Greater range, can penetrate walls—but may be more sensitive
• Useful in garages or outdoor areas

3. Dual-Technology Sensors

• Combine PIR and microwave for reduced false alarms
• Excellent for high-traffic areas or mixed environments

4. Pet-Immune Sensors

• Ignore movement from animals under a certain weight
• Let pets roam without setting off alarms

Where to Install Motion Sensors

Inside the home:

• Entryways and hallways
• Living rooms and staircases
• Basement doors or windows
• Near safes or valuables

Outside the home:

• Driveways and walkways
• Side gates or backyards
• Near detached garages or sheds
• Porch areas to deter package thieves

OnGuard professionals can assess your floor plan and layout to ensure strategic placement with zero blind spots.
