Buying Guide: Alarm Motion Sensors
📋 Table of Contents
1What detection range should I look for in an alarm motion sensor?
For most homes, a detection range of 15-30 feet is ideal, covering typical room sizes. Look for sensors with adjustable sensitivity to avoid false triggers from pets or moving objects, and ensure coverage overlaps with other sensors for full home security.
2What’s the difference between passive infrared (PIR) and microwave motion sensors?
PIR sensors detect heat from human bodies and are common in residential use, while microwave sensors use radar-like pulses and are more sensitive but prone to false alarms. PIR sensors are usually more affordable and energy-efficient for everyday home use.
3How important is the sensor’s field of view?
A wide field of view, typically 100-120 degrees, ensures better coverage without needing multiple sensors. A narrower angle may leave blind spots, especially in corners or along hallways, increasing the risk of missed intrusions.
4Should I choose a wired or wireless motion sensor?
Wired sensors offer more reliability and are less prone to interference, but require professional installation. Wireless sensors are easier to install and reposition, but may have shorter range and require regular battery replacements for optimal performance.
5What features should I look for in a smart motion sensor?
Look for integration with smart home systems like Alexa or Google Home, motion alerts via app, and adjustable sensitivity. Some models offer night vision or two-way audio, which can be useful for monitoring activity without additional cameras.
