If you notice that your system is failing to respond to commands from the Blink App than you may be experiencing Sync Module communication issues. The Module is the brain of the system and helps initiate commands from the App, to our Servers and back to you. For optimal system performance, your camera must share at least 3 or more bars of signal strength with your Sync Module. Putting a Sync Module in a hidden area can also reduce its visibility and cause it to suffer from interference. Some examples of poor locations are: located behind a Television, inside a closed cabinet, on top of your wireless router.
We recommend positioning your Sync Module in a "Man-in-the-Middle" style location, where it can receive a good signal from your WiFi router but also have visibility to your cameras. In some instances, you may need to only re-locate your camera.
If you continue to have difficulties with your Sync Module or camera, please contact Technical Support here.
