I cannot connect to the DVR over my LAN after configuring its network.

These are the items you should check if your DVR is not running on your LAN: 1. The Subnet and Gateway settings are correct and identical. 2. The IP address you have assigned is unique to your network. If not, try a different IP address. 3. The cable is the correct type and is not damaged. If damaged, change the cable out for another Ethernet cable. [If all of the above are correct, and you are still having trouble connecting to the DVR, please call our Technical Support.]
