How to Optimize Your Indoor Motion Sensors

Indoor motion sensors are a critical component of any comprehensive security system, acting as a secondary line of defense if an intruder bypasses perimeter door or window contacts. However, improper placement can lead to a frustrating string of false alarms or, worse, blind spots in your coverage.

Placement is Everything

The effectiveness of a motion sensor (typically passive infrared or "PIR") depends entirely on its location:

• Avoid Heat Sources: PIR sensors detect rapid changes in infrared energy (heat). Never point them directly at heating vents, fireplaces, or windows that receive intense direct sunlight, as sudden temperature fluctuations can trigger false alarms.
• Focus on Chokepoints: Place sensors in high-traffic areas that an intruder must pass through to navigate the house, such as main hallways, stairwells, or the master bedroom entrance.
• Corner Mounting: Mounting a sensor in the corner of a room typically provides the widest field of view, covering the majority of the open space.

Pet Immunity Features

If you have pets staying indoors while the alarm is armed, ensure your sensors feature "pet immunity." This technology calibrates the sensor to ignore the heat signatures and movements of animals under a certain weight threshold (usually up to 40 or 80 lbs), allowing your dog or cat to roam freely without triggering sirens.
