EZVIZ A3 Gateway
The EZVIZ A3 is a small home gateway (hub) that links EZVIZ ZigBee sensors and other compatible EZVIZ devices to the EZVIZ app. It connects to your router with a network cable or over 2.4 GHz Wi-Fi, talks to the sensors over ZigBee 3.0, and can manage up to 64 EZVIZ devices.
One hub for your EZVIZ sensors: EZVIZ sensors such as motion, door/window and button sensors do not connect to Wi-Fi themselves; they pair with the A3, and the A3 passes their events to the EZVIZ app. This lets you build a sensor-based alarm system at home and grow it over time, up to 64 compatible EZVIZ devices.
Control from the EZVIZ app: From your phone you can arm or disarm the system with one tap, get instant alerts when a sensor is triggered, and check the activity log at any time. Setup and control are done through the EZVIZ app.
Wired or Wi-Fi connection: The A3 can be connected to the router with an Ethernet cable (RJ45) or over 2.4 GHz Wi-Fi. A cable connection is useful when the hub sits next to the router, while Wi-Fi lets you place it anywhere in range.
20 alarm sounds: The gateway itself can sound an alert, and you can choose between 20 alarm sounds in the EZVIZ app, so the alert can be a loud alarm or a softer tone that suits your home.
Small size: At 70 mm in diameter and 25.4 mm high, the A3 can sit on a shelf, a desk or a bedside table without drawing attention. It is powered over Micro USB (5 V / 1 A).
Good to know
The A3 works with EZVIZ devices that are compatible with it; check that a sensor or device supports the A3 before buying it. Wi-Fi is 2.4 GHz only. The listed ZigBee and Wi-Fi range (under 200 m) was measured by EZVIZ in an open environment; walls and floors reduce it.
