I have the DVMR4E. When it boots, it displays Gen IV Technologies, and then shows DVMR4E Ver 4.0.
The Admin password was unknown, and the default of "1" did not work. But I figured out how to reset this unit's admin password.
The Admin password seems to be stored on the internal HDD. So if you disconnect the HDD, it will accept and use "1" (the default) for the admin password.
Here is how I reset the Admin password:
1. Power Off DVR
2. Open unit, and disconnect HDD power cord.
3. Power on DVR, let it boot. You'll see an error about HDD, ignore
4. Login as Admin using "1"
5. From the MAIN menu, select/enter MISCELLANEOUS
6. In Miscellaneous, Select HDD Information
7. Plug the HDD power back in (let it spin up and get ready, about 30 sec)
8. Choose HDD Auto Detect (mounts HDD)
9. Select MENU to go back to MISCELLANEOUS
10. Select ID/PW Setup
11. Choose Admin (for password change)
12. Leave OLD PW empty
13. Enter new Admin passwd and confirm
14. Select MENU
That writes your new password to the HDD.
MENU all the way back to camera screens
Power Off
Power On
Your new Admin password will be read from the HDD and used.
You should now be able to login using your new Admin passwd
