hello, I bought a Ganz DR16HL at an electronic fair and obviously the password is not the standard.......... but the big problem is also the network .... which is not in C class . I tried with an ip scan on all private classes but the dvr is not responding and , waiting for an answer on a public address ,is unthinkable.... it could take months. does anyone know a default password for this device? i have tried 6036xx and the other but they are wrong can you help me ???? tnx Max
