The EZVIZ A3 Home Gateway is the central control unit for your smart home security system, seamlessly linking EZVIZ sensors, cameras, and other devices into one unified network. Compact, reliable, and easy to set up, it allows you to manage up to 64 compatible devices and enjoy instant alerts, customizable alarm sounds, and flexible connectivity options. Whether you’re upgrading your home security or building it from scratch, the A3 ensures every device communicates perfectly, giving you total control at your fingertips.
Centralized Smart Home Control With The EZVIZ A3 Gateway
The A3 Home Gateway acts as the command center of your EZVIZ smart security ecosystem. It integrates with devices like the T1C PIR Motion Sensor, T2C Open/Close Sensor, and T3C Smart Button, enabling you to monitor, arm, or disarm your system effortlessly through the EZVIZ App.
With its ability to handle both wired and Wi-Fi connections, the A3 ensures stable performance. This makes it ideal for homeowners looking for smart home hubs that offer both flexibility and reliability.
Easy Setup And Effortless Management
Setting up the EZVIZ A3 Gateway is as simple as plug-and-play. You can connect it via an RJ45 Ethernet cable for maximum stability or use Wi-Fi 2.4 GHz for wireless convenience. Its compact design allows placement anywhere—on a nightstand, bookshelf, or coffee table—without taking up valuable space.
Once connected, the EZVIZ App provides a user-friendly interface for controlling your devices, checking activity logs, and customizing alerts. This is perfect for DIY smart home installations, eliminating the need for complex wiring or technical expertise.
Instant Alerts For Peace of Mind
With the A3 Home Gateway, you receive real-time notifications whenever a linked sensor detects activity. For example, if the T1C PIR Motion Sensor detects movement or the T2C Open/Close Sensor registers a door opening, your phone instantly alerts you.
This immediate response system ensures you can act quickly—whether you’re home or away—making it an essential tool for home intrusion detection and smart home monitoring.
Customizable Alarm Sounds
Unlike traditional security systems with a single loud siren, the EZVIZ A3 offers 20 different alert tones to suit your preferences. Options like Piano Keys, Ding, Laser, and Breeze allow you to pick sounds that match your home’s atmosphere.
Through the EZVIZ App, you can switch sounds anytime, making this an ideal feature for families with children, elderly members, or pets who may be startled by harsh alarms.
Supports up to 64 Devices for a Scalable Smart Home

EZVIZ A3 Gateway Sensor (64 Devices Linking)
The A3 Gateway can connect up to 32 battery-powered EZVIZ devices or up to 64 devices when wired units are included. This scalability means you can start with a few sensors and expand your system as your needs grow.
Compatible devices include:
-

Selected EZVIZ Cameras
The A3 also supports sensor-to-camera linking, meaning that when a sensor detects activity, your connected camera can automatically record a 5-second clip, giving you visual proof of what happened.
Smart Integration With EZVIZ Cameras

EZVIZ A3 Smart Integration With Cameras
When paired with compatible EZVIZ indoor PT cameras, the A3 enhances your security by enabling automatic recording upon sensor activation. Currently, the C6 Smart Camera supports auto-tracking, following movement in real time, while other models record from their fixed angle.
Future updates will expand this functionality to more EZVIZ cameras, making the A3 an investment-ready smart home hub.
