If the camera is unable to connect to the WiFi, the status light should be blinking red. If it is blinking a different color, please check the status light table here.
If it is not blinking at all, check that the mounting plate has good contact with the gold pins on the doorbell. Make sure the mounting plate isn't too tight that it is bending, preventing good contact with the gold pins. If something looks off or your not sure the Video Doorbell is installed correctly check out our installation guide for help!
If your status light is blinking red, please make sure that your wireless router is plugged in and within the range of the camera recommended by the manufacturer of your router. In addition, please make sure that the WiFi network is transmitting over 2.4ghz and not only 5ghz. If this problem continues, please contact customer support.
