Why is my Blink’s ‘Sync Module Offline’ & How to Fix it
The Blink Sync Module functions as the central hub for the Blink wireless home security camera system. It serves as a connection point between your Wi-Fi network and the Blink cameras, enabling you to remotely control and access them. Its main role is to facilitate the transfer of data and video footage captured by the cameras, which can be conveniently viewed and managed using the Blink app.
With the assistance of the Blink Sync Module, you can effortlessly keep an eye on your home or other locations from a remote location. It provides features such as motion alerts and the ability to review recorded video footage, enhancing your security and providing peace of mind.
