Troubleshoot Wi-Fi connection issues

Try the following steps if you're having trouble connecting your camera to Wi-Fi:

  • Make sure you’re connecting to a 2.4GHz Wi-Fi network (5GHz is not supported).
  • Double-check that your Wi-Fi name (SSID) and password are entered correctly.
  • Ensure the camera is within 33 feet (10 meters) of your Wi-Fi router.
  • Turn on Bluetooth on your phone during setup (no need to manually pair via Bluetooth).
  • If you changed your Wi-Fi password or the camera was disconnected: Press and hold the doorbell button until the camera resets. Re-add the camera to your app account and reconnect it to Wi-Fi.
  • 【MegaPixel】 1.0 Megapixel Ultra HD, Extra-Wide Angle, Delicate Image Quality, Clear Picture — every detail can still be captured even when you zoom in. It recognizes faces easily, so you don’t have to worry about grainy images. It also offers a 170° diagonal field of view, showing you everything you need to see outside the door.
  • 【Instant Notifications & Modular Chime】 Get instant push notifications when the doorbell button is pressed or adjust the volume for select times. The modular Chime design allows you to conveniently place your chime where you want, choose from several different tones, and adjust the volume directly on the device. Never miss another delivery or wake your family with an unexpected guest.
  • 【2-Way Audio】 This Smart home video doorbell gives you the ability to answer your door even when you're not home. Watch live from anywhere, anytime on your phone or favorite supported device, and carry on a crystal-clear 2-way conversation with a single tap on the app.
  • 【PIR Motion Detection & Real-time Alert】 This smart doorbell with a built-in camera is equipped with a PIR infrared sensor. It automatically captures abnormal activities at the door and pushes alerts to the APP. Both the sensing distance and the alert push interval offer 3 adjustable levels, minimizing false alarms to the greatest extent. When motion is detected, it will send a notification to your phone in 3s and record footage of visitors who approach your door. You can choose to talk to visitors or turn on the alarm to warn uninvited guests
  • 【Voice Changer】 You can stay safe even when you're home alone. Whether you're a woman living alone or a child staying at home by yourself, you can choose to use the voice-changing intercom function independently to protect your real identity and prevent harassment.
  • 【Infrared Night Vision】 Equipped with 6 built-in infrared LEDs and an ICR infrared filter, it can automatically switch between day and night modes according to the ambient light intensity.
  • 【Powerful Battery Life】 No frequent recharging required. Equipped with a 3600mAh rechargeable lithium battery, it is energy-efficient and environmentally friendly. Combined with the low-power Wi-Fi design, it can achieve a long battery life of up to 180 days.
  • 【Encrypted Cloud Storage for Ultimate Privacy】 Your security footage is protected with AES 128-bit encryption (subscription required), ensuring that only you can access and review your videos. Three days of rolling storage are included by default.
