Home Automation: FAQ

Will these sensors fit my existing doors and windows?

Check the physical dimensions in the product description carefully. Most modern sensors use compact designs with 3M adhesive backing, ensuring they fit standard global frames without drilling.

How do I ensure the sensor is durable and weather-resistant?

Look for an IP65 or IP67 rating for outdoor sensors to ensure water resistance. For indoor units, high-quality ABS plastic is the standard for long-term UV resistance and durability.

What technical specs indicate a high-quality alarm sensor?

Prioritize sensors with Zigbee 3.0 protocol for better battery life and mesh stability. Check for 'Low Battery Notification' features to ensure your security system never goes offline unexpectedly.

Are these delicate electronics safe during international shipping?

Reputable AliExpress sellers use anti-static bags and padded boxes. Opt for 'AliExpress Standard Shipping' to get better tracking and insurance for your electronic components.

Recommendations for buyers

  • Protocol Compatibility
    Ensure the sensor matches your existing hub protocol (WiFi, Zigbee, or Matter) to guarantee seamless integration with apps like Home Assistant, Alexa, or Google Home.
  • Battery Type & Longevity
    Look for sensors using standard CR2032 or CR123A lithium batteries, which typically offer 12-24 months of operation, significantly reducing maintenance frequency.
  • Response Latency
    High-quality motion and contact sensors should have a trigger delay of less than 200ms to ensure immediate automation or emergency alarm activation.
  • Mounting Versatility
    Choose sensors that include both high-bond adhesive tape and screw-mount options for flexible installation on various surfaces like wood, PVC, or metal.
