One of the issues is them using 10.10.25.XXX which some ISP will use that 24Bit address in their local network, which causes conflicts when a consumer uses that address pool.
This is how you would set these lorlex up:
The below is with a standard network connection with a dhcp and router address of 192.168.1.1 Subney mask 255.255.255.0 DHCP pool address range 192.168.1.2 thru 192.168.1.100
Step 1: With only he monitor and mouse connected to NVR (NO network or cams connected) In the menu: Under Advanced, click Maintenance to open the Maintenance tab. Click Load Default Reboot NVR to DAY 0 (defaults)
Step 2: when the NVR boots, go through the wizard and input the admin's password you want to use, then set up local , time, etc and exit out of the wizard.
Step 3: Under Settings, click Network, then click on the Switch tab, Click the fields next to IP Address, Subnet Mask and Gateway to edit IP address: 192.168.23.100 Subnet Mask: 255.255.255.0 Gateway: 192.168.23.1
Step 4: make sure DHCP is checked: Under Settings ->Network
Step 5 connect cameras. When you plug them in a port, they will appear with an ip address after first boot (3 minutes) if not, Under Advanced, click Maintenance , Click IPC Load Default. Check the cameras you would like to restore default settings for and click OK . After 5 minutes they should appear connected . This reset only will happen to cameras connected to the cam ports, and not past two switch levels on the LAN side. Sometimes, you have to connect the camera to the cam port if it doesn't reset over the network.
