Hi guys!!! any idea how to retrieve back the main password from this dvr,we have tried everything as it said in the manual but nothing,we email lorex support and got no response,we took out the battery from the bios and just lost the real time and year but the password remain unkwon,we can log on via http but cannot log in to the dvr to see or modify anything in the main menu. i thing if there a chance the only way is to use the factory room bin but no were to find it.
