+### Discrepancies between cameras
+
+1. Wifi Strength
+	- A9 reports '100%' strength
+	- X5 reports different strength values
+
+Seems like the A9 cameras brick themselves if you:
+1- Give them a bad wifi password
+2- Give them a good wifi password, with no internet
+
+Have not yet tried to give it internet access.
+
+After bricking itself, it reports very broken configuration via serial:
