Hello, I have a a Aver Media EB1304 MPEG4+ CCTV (that I bought from the no longer iviewcameras.co.uk) and I've lost the password. I opened it up and see that there are three contact points labelled "2-3 CLEAR PASSWORD" and also a jumper nearby with 4 connectors. The jumper is currently at position 1-2. I don't know what combination of power, battery, jumpers etc is required to reset the password. I tried leaving the battery out overnight and also connecting the 2-3 contacts with a paper clip, but the password is still not the default.
