“What Are the Two Network Ports on an NVR Used For, Respectively?”
Hello everyone, in this issue we'll give a quick, simple explanation of what the two ports on an NVR (Network Video Recorder) are used for.
Customers often ask us what the two ports on an NVR are used for.
Today we'll give a quick, simple explanation of what the two ports on an NVR are used for.
First, let's introduce the NVR. NVR stands for Network Video Recorder, a device that receives video files from IP cameras over the network for centralized viewing, management, and remote functions. Built on an IP-based architecture, the NVR is simple to install and easy to use, offering great flexibility when building a surveillance system. It helps users achieve 24-hour continuous recording and monitoring at home, in the office, and other locations.
- One network connects to the cameras, and the other connects to the external network (the Internet)
The benefit of this setup is that it isolates the external connection from the camera network — meaning external connections cannot directly reach the cameras — making the system relatively
secure.
- It can also serve as load balancing: once the number of cameras reaches a certain scale, both networks can be set to connect to the cameras. If one network has a problem, the other network can keep the system running.
