I have a AV Tech AV760 DVR. I need to do a download via the network port. I have loaded the software onto my laptop but since them have lost the CD and manual. I have tried to connect the laptop to the DVR back cannot get a an auto connection. Because i have lost the CD I don't have the IP address or the password. Could anyone help with either the IP address and password / any advise on connecting via the network port or better still with a manual.
