DS-2CD2342WD-I not working in NVR (DS-7104N-SN/P)

[mudassar.hassan]

Previously the cameras were working, but after reset it is no longer working. There are some other old cameras which are working fine , the DS-2CD2342WD-I are added but unable to get live preview or record.

NVR Firmware = 3.0.13 build 150503
Encoding version = 150413

Any help will be appreciated. Thanks
