📋 目次
1What detection range should I look for in a PIR motion detector?
For indoor use, look for a detection range of 15-30 feet (4.5-9 meters) with a 120-degree horizontal field of view. Outdoor models often have a longer range, up to 50 feet (15 meters), but may require a higher voltage or weatherproof housing for reliability.
2What’s the difference between passive and active PIR motion detectors?
Passive PIR detectors sense infrared energy from moving objects without emitting any signals, making them energy-efficient and quiet. Active PIR detectors emit a signal and measure the reflection, offering better accuracy in low-light or complex environments, but they are more expensive and consume more power.
3How does the sensitivity setting affect performance?
Higher sensitivity can trigger false alarms from small movements like pets or drafts, while lower sensitivity may miss actual motion. Look for models with adjustable sensitivity settings to balance between responsiveness and false triggers based on your environment.
4What should I consider when choosing between wired and wireless PIR detectors?
Wired detectors are more reliable and less prone to interference but require professional installation. Wireless models are easier to install and reposition but may have limited range and require regular battery replacements, typically every 6-12 months.
5Are there any common mistakes to avoid when installing PIR motion detectors?
Avoid placing detectors near heat sources, air vents, or areas with direct sunlight, as these can cause false triggers. Also, ensure they are mounted at the correct height (typically 6-8 feet) and angled to cover the desired area without blind spots.
