EZVIZ CS-B1 Home Sensor Kit – Zigbee 3.0 Gateway, PIR Motion Sensor & Contact Sensor, Wi-Fi, 90 dB Siren, White

The EZVIZ CS-B1 Home Sensor Kit is a complete smart security foundation that combines a Zigbee 3.0 gateway, a PIR motion sensor, and a contact sensor to safeguard your home. The gateway connects to your 2.4 GHz Wi-Fi network and acts as the central hub, supporting up to 64 Zigbee devices for seamless expansion. Its built-in 90 dB siren and 2000 mAh backup battery ensure protection even during power outages, keeping your home secure around the clock.

Advantages

Connect up to 64 Zigbee devices through the A3 gateway, which pairs with your 2.4 GHz Wi-Fi network for reliable remote control via the EZVIZ App. The PIR sensor detects movement up to 7 meters away across a 90° angle, while the contact sensor monitors doors and windows. Both sensors run on replaceable coin-cell batteries lasting up to two years, minimizing maintenance. The gateway's backup battery provides up to 8 hours of operation during power interruptions, and the 90 dB siren deters intruders with a loud alarm.

Suitable for

• Apartments and houses needing entry-point monitoring
• Users building a scalable Zigbee smart home ecosystem
• Renters seeking adhesive-mounted, non-invasive security
• Areas with occasional power interruptions thanks to gateway backup
