To ensure optimal performance, do not exceed the maximum number of cameras that can be viewed on each client workstation type in Security Center 5.9.

The maximum number of H.264 camera streams supported by each client workstation profile is as follows:

Performance benchmark for HEVC (H.265)

The following benchmark illustrates the average bit rate of a camera streaming at 20 fps using HEVC (H.265) video format.

The viewing workstation has a 4th Generation Intel® Core™ i7-4770 @ 3.5 GHz processor, with 16 GB RAM, an SSD hard drive, and runs Windows 8.1. The video card used is an NVIDIA® GeForce® GTX 1060 with 6 GB of RAM connected to a 4K monitor.

Encryption impact on workstation performance

Video encryption can increase the CPU usage by up to 40% when viewing low-resolution video (CIF). The impact becomes less noticeable as the resolution of the video increases, because much more processing power is spent on decoding the video than on decrypting the video. The impact on performance becomes unnoticeable when viewing HD and Ultra-HD video.

Watermark impact on workstation performance

Video watermarks are rendered by the client workstation. This extra load reduces the maximum number of live and playback video streams that can be displayed simultaneously. On average, the maximum number of tiles that can be displayed when hardware acceleration is enabled is reduced by 10%. This reduction reaches 30% on machines without hardware acceleration. The performance impact increases with the video resolution.
