After reaching v3.4.92 and performing a full factory default, an upgrade directly to v4.50.00 is acceptable.There is a high chance of unit failure (requiring RMA) if the unit is not defaulted before upgrade. If the recorder is already at v3.4.92, a full factory default is highly recommended before upgrading to any version of v4.X.Upgrading from versions before v3.4.92 directly to any version of v4.X will likely cause the recorder to fail. All recorders must reach v3.4.92 before proceeding further.Upgrading from v3.4.92 build 170518 or Older If you are experiencing issues where playback is expected but not found, make sure 'Database Repair' is performed as indicated in the procedures and scenarios below.īefore proceeding with upgrade, it is recommended that NVR configuration file is exported from the NVR over the network or on to a local USB drive.
