Recently purchased a LTE-DVR8 nightowldvr 8 channel,Can remote view,and somewhat remote admin via netviewer and CMS. I am trying to telnet with the embedded OS but to no avail,can not find correct logon and password.Is anybody aware of a default logon and password for the night owl dvr's? Via Putty and Windows telnet I get this logon: 
(none)logon: 
password: 
  
Been at this a few days, any suggestions will be greatly appreciated.
