Hello all,

We have three DVRs set up for security camera recording and live feeds. Let's call the three "box A, box B, and box C."

Box A and box C work completely fine. We had replaced the hard drive in box A after a hard drive failure and it now works fine. However, since the same day we did this, the ptz cameras connected to box B are no longer detected by box B.
Nothing about box B seems to be wrong or has changed, the coax cable connections are still tight and secure, and we can see the cameras connected to box B still have power and are still maintaining their programming, as they are still panning and such along their routine route. They are just not being detected or recorded and we cannot see the live feed from them.
All three boxes are using their own static IP and the cable connections have also been reestablished just in case. I had also both rebooted and power cycled box B, but the issue persists.

Model number for box A is CVR116H-S3
Model number for box B and C is PVR16H1-X

Wanted to see if anyone had a similar problem, before going through the hassle of taking down the cameras and/or replacing them.

Thank you.
