Frequently Asked Question - Technical Department
1 Physical Connections: Inspect the physical connections such as sockets, cables, power supply to the equipment, and the correct interface between devices in terms of bandwidth (10/100/1000 Mbps). The network ports on “KDT” recorders support a bandwidth of 1000 Mbps. Naturally, the NVR port, when connected to a 1000 Mbps port on the switch, will provide you with the highest bandwidth.
2 Network Design: If you are using multiple switches in your network design, consider that the star topology is the most suitable method for connecting switches to each other.
3 IP Address Conflicts: Check all network-connected devices for different IP addresses (while maintaining the same IP range) to ensure there is no “IP conflict.”
4 NVR Camera Setup: When configuring cameras on the NVR device, ensure that the username and password are entered correctly.
5 Camera Settings: Like other equipment, cameras should be configured according to the project’s conditions and limitations. Default settings are not necessarily always the best settings.
6 Network Ports: In organizational and protected networks, the ports through which CCTV equipment communicates may be closed. After checking, if the ports are closed, ask the network administrator to open the relevant ports for you.
7 Firewall and Antivirus: Ensure that the firewall and antivirus are turned off when connecting your camera or NVR to a computer.
first ensure the correct physical connection between network equipment. If the camera and NVR brands are different, you should use the Onvif protocol to add the camera. In such cases, the IP of the camera and NVR should be set in the same range beforehand.

This issue occurs when the network bandwidth is insufficient to meet the cameras’ needs for image transmission. The cause is often either incorrect software settings (such as increasing the camera’s Bit Rate beyond standard levels and its mismatch with frame rate and resolution) or improper network design and connections (such as connecting the NVR network port to a 100 Mbps switch port, which reduces the NVR’s bandwidth by ten times compared to a 1000 Mbps connection)
