The minimum requirements largely depend on the method used for recording and the number of cameras recorded simultaneously.

IMPORTANT: The requirements listed below are guidelines; actual requirements may vary and cannot be specified precisely due to the rapidly changing hardware and software landscape and the many unknown factors in a more complex lab environment.

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.

More sources or higher resolutions and/or frame rates do not only influence the required capacity on the computer itself, it also increases the network load!

Four-Camera Setup

Presuming standard Audio requirements with one or two microphones.

RTSP-Method

To simultaneously record 4 HD IP-cameras, using the Streaming sources method, these are the minimum requirements for your computer:

 

AMC-Method

To simultaneously record 4 HD IP cameras, using the 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 a professional Nvidia Quadro or RTX video card to handle more than 3 'streaming-sources' simultaneously.

Eight-Camera Setup

Presuming standard Audio requirements with one or two microphones.

RTSP-Method

To simultaneously record 8 HD IP cameras, using the Streaming sources method, these are the minimum requirements for your computer:

AMC-Method

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

IMPORTANT: Recording more than 8 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 6 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.

Note: When more than 8 cameras must be recorded, our Master/Slave capability allows us to scale the lab to handle more cameras in a single session.

Recording Video Streams

If you are using RTSP or NDI 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.

Note: 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.
