Smart Security Sensors: Zigbee / Tuya OEM China
5 resources tagged with "Security Sensors"
Security sensors from China — door/window contacts, PIR motion, mmWave presence, water-leak, and temp/humidity — split mainly on radio: Zigbee 3.0, Tuya WiFi, Z-Wave 700, or Matter/Thread. The detail buyers underestimate is battery life claims: a PIR sensor rated 1–3 years and a contact sensor rated 1–2 years depend heavily on trigger frequency, so verify the test conditions behind the number. OEM orders usually start at 500 units, with FCC/CE/RoHS for Western markets and SASO plus CST radio approval for the Gulf.
When you source security sensors, the radio protocol decides which hubs and ecosystems they join, and mixing protocols across a product line fragments your support burden. The common pitfall is mmWave presence sensors: 24GHz vs 60GHz radar have different detection zones and regulatory radio approvals, and false triggers from poor antenna tuning are a frequent field complaint.

FAQ
What MOQ and certs apply to OEM security sensors?
Most factories quote from 500 units per model. Western markets need FCC, CE, and RoHS; the Gulf needs SASO/SABER plus CST/CITC radio approval. Battery-shipped sensors with cells may also need UN 38.3 for transport.
Are the advertised battery lifespans reliable?
Treat them as best-case. A 2-year claim assumes a defined trigger rate and temperature; high-traffic doors or cold environments shorten it. Ask for the test conditions and consider field-testing a small batch before committing.
What's the difference between 24GHz and 60GHz mmWave sensors?
Both detect presence by radar, but 60GHz offers finer resolution and smaller zones while 24GHz covers wider areas. They carry different radio approvals per market, so confirm the band is approved for your destination before ordering.
