Under Device Info for each of your devices in the Wyze app, it will show you the name of the wifi network it is connected to, and a little signal strength bar chart, but that is not very accurate or precise.
Instead, get one of those free wifi scanner apps for your phone, that shows all the wifi signals in range. They will display the wifi signal strength. I have tried a few, and NetAnalyzer (Android) works well for me.
Then run the wifi scanner app on your phone and hold it near your camera,
Look in the app in the 2.4 GHz wifi frequency band for your wifi name your camera/device is connected to, and look at the signal strength. The app should rescan every few seconds or so. Note the signal strength readings for 4 or 5 scans, discard any results that are way out of range from the other readings, and average the values (to eliminate any flukes in the readings)
The wifi signal strength is measured in dBm, and is a negative value. The closer to zero, the stronger the signal. Anything less that -70 dBm is considered an unreliable/weak signal. Less that -80 dBm and pretty much nothing will connect or stay connected, and will be useless. Greater (closer to zero) than -30 is fantastic.
This will not tell you the data rate, but it will give you a very good measure of the signal strength available to your device, which will tell you how well it will stay connected - the stronger the signal, the better it will stay connected and the faster data rate it will have.
If it is not strong enough for you, try moving the camera (or your phone) a few feet in some direction, maybe closer to your wifi router, or perhaps to one side or the other. The signal strength can vary depending on how may walls and what the walls are made of, so moving it closer to a doorway can sometimes help. Or even turning the camera angle can change the signal reception.
Your device shape, antenna position, orientation, etc, can affect the signal strength, and your phone will have different characteristics than your wyze devices, so your phone might have better reception than your device, so this won’t be an exact measure, but it should be very close.
Some of the fancier apps (usually paid) have options to build “heat” maps of the signal strength for you. You upload a basic “map” of your home, then stand in certain positions in your house, you tell the app where you are on the map, and then run the scan. You do this at various places around your home, and it will build a map of where the strongest and weakest points are in your house. You can reposition your router, or even its antennas or direction it faces to change the strength at various places.
I built my own map, by going to different places in my house, sometimes at different places in the same room, and wrote down all the readings, and came up with the signal strength within my house at those places, so I could tell if there might be a dead spot, or if I had to move the router or move my wyze devices around a bit.
