You may follow the steps below to initially set up your battery-powered WiFi camera via Reolink App.

Step 1. Power on the camera. Remember to turn on the power switch on the camera before initial setup except for Argus 2 and Argus Pro. After a startup sound, you will hear a repeated Ding sound or a voice prompt. 


  • The voice prompt you will hear may be “Welcome to Reolink, please install Reolink app and scan the QR code on the camera” in multilingual versions, or “please run Reolink app, add the camera and set it up”.
  • After you power on the camera, the status light on the front of the camera will turn on in red color, then it will turn off about 3s later.

Step 2. Tap the icon in the top right corner to start the initial setup.

Step 3. Scan the QR code on the back of the camera. You may tap Light to enable a flashlight when setting up the camera in a dark environment. If the phone doesn't respond, please tap Input UID/IP and then manually type in the UID (16-digit characters under the QR code of the camera). Then tap Next.


Step 4. Select Wi-Fi Not Configured. If you hear a voice prompt played by the camera, please tick correspondingly and then tap Next.


Step 5. Enter the WiFi password of the selected WiFi network (you may tap the right eye icon to see and double-check the password) and tap Next


Note: Argus 3 Pro, Argus Eco Pro, Argus PT (5/2.45GHz), Argus 3 Ultra, Argus Eco Ultra, Argus PT Ultra, Argus Track, Duo (battery), Duo 2 (battery), TrackMix (battery) can support 5GHz/2.4GHz Dual-Band WiFi connection.

Step 6. Tap Scan Now. Place the QR code on your phone in front of the camera’s lens at a distance of about 20 cm (8 inches) and let the camera scan the QR code. Tick correspondingly and tap Next.


Note: For Argus Eco and Reolink Duo (Battery), the scan distance is around 30 cm (12 inches).

Step 7. Wait around 60 seconds for the camera to connect to the router. After hearing “connection to the router succeeded”, tick correspondingly and tap Next.

If you hear “Connection to the router failed” or you still can't access the camera even though you hear “Connection to the router succeeded”, please tap troubleshoot.


Step 8. Create a login password and then name your camera. 


Step 9. Select a scene according to the place where your camera will be installed, then click Next.


Note: Currently, only Argus 3 Pro, Argus PT (5/2.4GHz), Argus 3 2K, and Argus PT 2K have the scene selection option.

Step 10. Read the note below and then tap Finish to complete the initialization of your camera.


Once the initial setup is completed, please choose a good position to mount your camera.
