There are two signal strength values that are displayed under the camera settings. One is called “Camera to Wifi” and the other “Camera to Sync Module”. I assume “Camera to Sync Module” is the low frequency radio channel used between the camera and sync module. I first thought that “Camera to Wifi” was actually the Sync Module’s wifi signal strength, but I have some cameras showing 3 bars and others 2. If it was actually the sync module wifi strength, it would be the same on all cameras so this isn’t what it is. What is it then? The camera’s don’t use wifi so I am very confused.
