1. Decide where it will be installed
Think about an entrance, hallway, cupboard, staircase or another location. Check the available mounting surface and whether the sensor will have a clear view of the area where movement is expected.
2. Understand the power source
Confirm whether the product uses batteries, USB power, mains power or another method. For battery-operated products, check the stated battery type and whether batteries are included.
3. Check detection information
Review the manufacturer's stated detection range, sensing angle or activation conditions where those details are provided. Real-world performance can depend on placement and the surrounding environment.
4. Compare brightness and lighting mode
Look for the stated brightness information and whether the light has modes such as automatic, manual or dim settings. Compare the mode you need rather than assuming more brightness is always better.
5. Check installation requirements
Review adhesive, screws, clips or other mounting methods and make sure the installation surface is suitable.
6. Consider environment and maintenance
For outdoor or damp locations, check the product's stated environmental or water-resistance rating before use. Also consider how easy it is to replace batteries or clean the sensor.
