I am currently using a Swann NVR8-7250 with 4 Swann bullet cameras.
I recently purchased 4 more cameras from Amazon, Amvrest qCam 3mp POE. I plugged the cameras into the NVR and the system will not recognize them. They power up but I'm unable to view any of them.
Can someone point me in the right direction. I appreciate your help.
