I have added 6 new cameras to the existing fleet of 8, so I needed a larger capacity NVR in order to display all the cameras on a single screen.. I was using the 7608NI and I bought a 7616NI to replace it. I set the same admin user and password on the new NVR and added the 6 new cameras without issue. When I try to plug in one of cameras previously attached to the 7608, I get username or password is wrong. The username and password is the same though. I then tried adding the camera manually typing in the password, I get the same message. All the previous cameras except one AXIS camera were new HIKs and added via plug and play to the 7608. They should have the same password as the 7608 NVR admin login, no? Is it really necessary to reset all 8 cameras to factory in order to add them to the new NVR? I hope I am missing something and it doesn't require something so ridiculous 
Appreciate any input folks,
