1. LAN environment: Make sure your PC/Laptop sits as the same network segment as the AVer NVRs. (For example, set IP address 192.168.1.x and subnet mask 255.255.255.0 for PC / Laptop in network settings in Microsoft Windows Operating System and set IP address 192.168.1.x and subnet mask 255.255.255.0 for the AVer NVRs.)

   In some of the cases, strange IP address or subnet mask gets randomly generated by direct connection between the DVRs and a PC / Laptop. So, it is also important to make sure to set same subnet mask (ex: 255.255.255.0) for the network device.

2. WAN environment (Internet): As the LAN IP address (For example, 192.168.x.x, 10.x.x.x) is not possible to be viewed via the Internet, so a network router device is needed in such case to forward the LAN IP address to router’s external IP address (static IP address), so that user can see the DVR live image from the outside of the Internet. Please check the user manual of the router device for detail port forwarding settings.
3. Password protection: Make sure the login password of DVR has not been changed. Otherwise, it may also cause possible web browser login failed. Check your system administrator if needed.
4. Network security setting: Check your IT management department to make sure there is no possible network security / firewall setting that may block the network sessions. Also, there are some security / anti-virus software or web browser firewall settings which may also cause the network session failed, it is better to adjust the network security policy settings to clarify the root cause in advance.
5. Ethernet cabling: Make sure the Ethernet cable is well connected on both network switch (Or the Hub device) and DVR side, and check the status of light indicators on those related devices. However, some disconnection issues may be caused by faulty Ethernet cables, so that user may need to make the cross-test on different Ethernet cables.
