Release Date: Jan. 2, 2026
Applied to
- GV-Control Center V4.3.0
- GV-VMS V17.4.8 / V18.3.5 / V20.0.2
This technical notice evaluates the performance of GV-Control Center, which displays IP channels of various resolutions from GV-VMS and GV-Recording Server / IP cameras in a variety of live view layouts. The live view layouts were carried out with 4K (3840 x 2160) screen resolution. When the performance testing was run, the CPU was at about 70% to 80% utilization.
The performance results were collected using H.264 and H.265 GPU decoding. Decoding is added to reduce CPU load and boost the maximum frame rate. For further information, see 1. GPU Decoding Specifications in this document.
In the performance testing, the sub stream from GV-VMS V17 / V18 is compressed by default. In contrast, the sub stream from GV-VMS V20 is bypassed (FIFO) by default, and the sub stream from GV-Recording Server / IP cameras is always bypassed (FIFO). Using FIFO ensures that the videos are not compressed on the hosts and are transmitted straight to the GV-Control Center.
In multi-channel layouts, the Force Substream option is disabled by default, so live view and playback use the main stream when available. When enabled, they use the sub stream when available, increasing the number of full-frame channels supported.
