If you are unable to login to the white NVR box from the wireless kits (ZMD-NV-SBN4 or ZP-NB14), first trying using the defaults:
Username: admin (all lowercase)
If the defaults are not working, you can restore the password to factory defaults by removing the top case of the NVR and jumping the two pins on the motherboard as shown below.
To do this, you only need to use a flathead screwdriver or metal paper clip to connect the two pins together. Make sure the metal of the screwdriver or paper clip connects both pins to reset the password. After around 20-30 seconds the NVR should automatically reboot and now be at the default username and password.Tags: KNS4-IASFZ4ZN, ZMD-NV-SBN4, ZP-KB1I04-W, ZP-NB14
