Servers running VMS version 6.x or later on x64 processors support up to 256 resources.
Servers running VMS version 5.x on x64 processors support up to 128 resources.
Servers using ARM processors are limited to 12 resources per server.
These limits are based on internal performance testing to ensure maximum scalability without degrading system performance or video stream quality.
| Note: These limits are not enforced by the VMS configuration itself. Actual performance can vary depending on the hardware, operating system, and background processes. It’s strongly recommended to maintain some available capacity on each server to handle failover events, maintenance, or temporary load spikes. |
What Are Resources?
Resources refer to any items that can be connected to the Mediaserver, including:
Camera channels
Encoder channels
I/O devices
Speakers
| Note: Multisensor Devices: Each sensor channel counts as a separate resource. For example, a multisensor camera with 4 sensors counts as 4 resources. |
Additional information
Each server creates up to 4 threads per media stream. Therefore, a server handling 256 cameras can generate up to 1,024 CPU threads, depending on stream configuration.
- Thread 1: Reads high quality RTSP stream from camera
- Thread 2: Reads low quality RTSP stream from camera
- Thread 3: Processes high quality RTSP stream and convert it to a MKV file
- Thread 4: Processes low quality RTSP stream and convert it to a MKV file
