To ensure optimal performance, don't exceed the maximum number of cameras that can be viewed on each client workstation type in Security Center 5.13.
The maximum number of camera streams supported by each client workstation profile is as follows:
| Decoding benchmark | ||||||
|---|---|---|---|---|---|---|
| Resolution @ 30fps | HD – 1280 x 720 | Full HD – 1920 x 1080 | Ultra HD – 3840 x 2160 | |||
| H.264 | HEVC (H.265) | H.264 | HEVC (H.265) | H.264 | HEVC (H.265) | |
| Average bit rate per camera (Mbps) | 2.0 | 1.4 | 4.8 | 3.2 | 19 | 13.4 |
| Minimum | 6 | 6 | 3 | 3 | 1 | 1 |
| Recommended1 | 58 | 58 | 30 | 52 | 8 | 18 |
| High-performance1 | 96 | 98 | 60 | 84 | 16 | 32 |
1 This refers to the maximum number of streams at full capacity (85% CPU and GPU use) in a static environment (video wall). Reducing the number of streams is required based on an active operator scenario and the use of other features such as visual tracking and guard tours.

GPU considerations
- If your Intel® processors support Intel® Quick Sync Video, you can use this technology if the monitor is connected to the motherboard. Laptops can also use Quick Sync Video.
- Security Center supports NVIDIA graphics cards. Due to compatibility issues, Genetec Security Center 5.13 does not support the NVIDIA RTX 50 Series GPU.
- You can use two or more graphics cards to support different monitors individually. To ensure that video decoding is performed on a specific cards, at least one monitor must be connected to each card.
- Activating hardware acceleration can generate a slight video decoding delay.
Encryption impact on workstation performance
Video encryption can increase the CPU usage by up to 40% when viewing low-resolution video (CIF). As the resolution of the video increases, the impact is less noticeable because it takes more processing power to decode video than to decrypt video. The impact on performance becomes negligible for 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.
