Motion Sensor Alarms & Infrared Detectors

Motion-Activated Security Alarms for Home Protection

Motion sensor alarms use infrared technology to detect movement and sound loud alarms when triggered. Protect entry points, hallways, driveways, and perimeter areas with invisible detection beams. Battery-powered standalone units require no wiring or installation.

How Motion Sensor Alarms Work:

PIR (Passive Infrared) sensors detect heat signatures from people or animals moving through detection zone. When motion detected, alarm sounds immediately to alert occupants and deter intruders. Invisible infrared beams create protective barrier that cannot be seen but triggers when crossed.

Motion Alarm Types:

Motion-Activated Barking Dog Alarms

Alarm emits realistic barking sounds when motion detected. 120dB siren option for maximum alert. Detection range up to 10 feet. Deters intruders who avoid homes with dogs. Works through doors and windows.

PIR Motion Sensor Alarms

Standard motion detection alarms with adjustable sensitivity. Detect movement in coverage area and sound loud alarm. Battery-powered for placement anywhere. Adjustable detection range and alarm volume.

Driveway Motion Alarms

Outdoor-rated sensors for driveways and property perimeter. Alert when vehicles or people approach home. Long-range detection (up to 400 feet on some models). Weatherproof construction.

Best Uses for Motion Alarms:

  • Entry Points: Doors, windows, garage entries
  • Hallways: Alert to movement inside home while sleeping
  • Driveways: Know when vehicles or people approach property
  • Perimeter Defense: Create invisible barrier around home exterior
  • Basements: Alert to unexpected entry to lower levels
  • Business Security: After-hours intrusion detection
  • Garages & Sheds: Protect detached structures

Key Features:

  • Detection Range: 10-400 feet depending on model
  • Alarm Volume: 100-120dB loud sirens
  • Power: Battery-operated (no wiring required)
  • Adjustable Sensitivity: Prevent false alarms from small animals
  • Multiple Modes: Chime, alarm, or barking dog sounds
  • Weatherproof: Outdoor-rated models available

Advantages of Motion Sensor Alarms:

  • No Wiring Required: Battery-powered for easy placement anywhere
  • Invisible Protection: Intruder doesn't see sensor until alarm sounds
  • Instant Alert: Alarm sounds immediately when motion detected
  • Scalable: Add multiple sensors for whole-home coverage
  • Affordable: Cost-effective vs. professional security systems
  • DIY Installation: No monthly fees or professional installation

Motion Alarms vs. Other Home Security:

Motion Alarms: Detect movement and sound alarm, no recording, battery-powered, DIY setup

Security Cameras: Record video, remote monitoring, requires power/WiFi, higher cost

Door/Window Alarms: Trigger when opened, don't detect motion, simpler design

Installation Tips:

  • Mount sensors 6-8 feet high for optimal coverage
  • Aim sensor across likely entry paths (not directly at door)
  • Avoid pointing at heat sources (vents, windows with direct sun)
  • Test detection range and adjust sensitivity
  • Use multiple sensors for comprehensive coverage
  • Replace batteries annually or when low-battery indicator sounds

Preventing False Alarms:

  • Adjust sensitivity to ignore small pets
  • Position away from moving plants, curtains, or decorations
  • Keep sensor lens clean of dust and debris
  • Avoid areas with temperature fluctuations
  • Test placement before finalizing mounting location
