The minimum requirements largely depend on the method used for recording and the number of cameras recorded simultaneously. The requirements below are indications; actual requirements may vary.

Note: Currently, the live preview of all cameras requires most of the GPU power. Meaning that (should your system be a bit low on GPU and CPU power, causing the preview to become jerky and delayed), the recordings itself are still OK and in sync. Minimizing the preview window increases the available resources for recording.

General Requirements

oEnough local storage to save your recordings, best on an SSD.

The required space depends on various elements:

oThe number of videos recorded per session.

oDuration of the recordings session.

oThe resolution of the cameras.

oThe amount of movement happening in front of the cameras the recording.

Four-Camera Setup

To simultaneously record 4 HD IP cameras, using the default Axis source method, these are the minimum requirements for your computer:

 

IMPORTANT: If you need to record videos streams or other Windows devices, all encoding is done on the computer itself (when using Axis sources, the encoded video stream is created on the camera itself, which saves a whole lot of computer resources).
This means that you need at least an Nvidia Quadro P2000 to handle more than 3 'streaming-sources' simultaneously.

Eight-Camera Setup

To simultaneously record 8 HD IP cameras, using the default Axis source method, these are the minimum requirements for your computer:

IMPORTANT: Recording 8 or more cameras on a single recording station only works for Axis sources, when using video streams and other Windows devices, we recommend to limit the number to 4-5 cameras on a single recording station. If more camera views are required and the default Axis source type cannot be used, an additional Slave-Recording-System is required.

Recording Video Streams

If you are using the videos streams method for recording, make sure you install an Nvidia graphics board that can handle enough concurrent streams! A great reference Matrix is provided by Nvidia:

Make sure you select Encoding and switch to the Professional (NVIDIA RTX/Quadro) tab. Pay attention to the column Max # of concurrent sessions.
For replaying many videos in sync, the number of NVENC may become important.

*) Comparable AMD** graphic boards as well an onboard Intel graphic chips (starting from HD 4001) works too.

**) There is no hardware decoder support for AMD graphic boards. For onboard Intel graphics, QuickSync supports for decoding.
