Alarm.com Doorbell Video Camera (ADC-VDB105 and VDB106) Not Communicating

Causes of Camera Communication Issues

  • • Distance to the Wi-Fi signal source may exceed the maximum range limit.
  • • Physical materials may hamper the signal, such as heavy concrete or thick metal walls.
  • • Electronic interference may be caused by devices that either emit a similar signal or utilize a significant amount of bandwidth, leaving too little bandwidth for the camera to communicate.
  • • Wi-Fi changes, including changing service providers or replacing a router, will require reconnecting the camera with the new Wi-Fi name and password.

Troubleshooting Cameras

  • • Address proximity issues by either moving the signal source/Wi-Fi router closer to the camera, moving the camera closer to the signal source/Wi-Fi router or installing a new signal extender to bridge the gap.
  • • For dense materials obstructing the signal, changes in camera placement can improve the connection, such as moving an external camera closer to a window or interior wall. A signal extender may also help with this.
  • • If new electronics interfere with camera communication, this is usually apparent when the new electronic device recently changes. Adding a new television, for instance, between the camera and the signal source is a common cause. Adjustments in the placement of either the camera or the new electronic device can mitigate this issue.
  • • Sometimes, it is prudent to perform a full reset on the camera in order to reconnect it to the Wi-Fi. See below for instructions to power cycle and reset the camera to factory defaults.

Camera Instructions

  • To reset the camera to factory defaults, press and hold the WPS/Reset button until the LED is flashing green and red (about 15 seconds), then release the button. The camera will reboot to factory default.
  • If the camera was previously installed on an Alarm.com account, it will need to be deleted before it can be installed again.
