I have a SPECO #/DVR-4TN160 that was given to me by a customer, 2 yrs ago, that upgraded to a MAC compatible unit. This older DVR has been sitting around the shop for a while doing nothing. Want to give it to a customer who has had a lot of trouble with with a SPECO IP Camera that Speco unable to fix or replace under warranty.

Unfortunately, don't know & cant find documentation for password so we can get in & reformat drive. Speco default doesn't work. Speco tech support wants us to send in & charge to be reformatted.

Anyone out there no if the secrete to getting around sending to speco & being charged to blow out password?
