I got locked out and the battery inside the DVR for HD is already failing so I changed it and now the whole DVR is working fine. but the dates was changed to 1960's and i forgot my password so i called the support and they will give you passwords for different dates but they couldn't give the password for the dates that the dvr was on. and the only resolution that they are offering is for me to buy a new one. what the actual fNENEV User's recommendation: Never buy AMCREST.
