Step 3: Pls kindly note the third photo which shows 1V 2V 3V...8V.
V means newtork cable is connected well. If the screen shows 1X 2X
3X...8X, then it means the network is disconnected. From the above three
photos, we can find that there is no problem for your network cable
which means the UTP testing is successful. "No signal " means you have
not yet connected the cameras, and it does not mean there is problem
with the UTP function.
