There are two components to consider when looking at FortiRecorder performance – the NVR (FortiRecorder) and the Client computer with FortiRecorder Central or a browser. Overall FortiRecorder performance is a combination of the video input (video compression, image quality level, complexity of the scene, video resolution, frame rate per second, number of cameras) and the video output (to the clients for live views and playback). The performance bottleneck in a FortiCamera deployment will likely be the network bandwidth to and from FortiRecorder and the CPU performance of the computer running the FortiRecorder Central or browser client, which must decode and render the video streams from the NVR. Displaying multiple video streams on the client is very CPU intensive.
