USB 3.0 port, Intel and Renesas chipsets only! (others brands may or may not work)
DirectX 11 capable GPU (Intel HD4000, AMD Radeon HD6470M / HD6570, NVIDIA Geforce 610M or above)
4 GB or more RAM
i5/i7 CPU 3GHz or faster
1280×1024 screen (recommended: 1920×1080 or higher)


  • What are the minimum GPU chipsets?

Intel HD 4400 integrated display adapter
ATI Radeon HD 5400 series
ATI Radeon HD 6570
ATI Radeon HD 7800 (256-bit GDDR5 2GB/1000Mhz)
NVidia Quadro 600
NVidia GeForce GT 640
NVidia GeForce GTX 660
NVidia Quadro K1000M


  • Is there an upgrade discount for v1 license owners?

Yes, please contact me providing your name and/or email used in your the v1 purchase.
I’ll send you a personal coupon code for a 30% discount on the v2 software.


  • Which sensor does this work with, and where can I buy one?

Kinect for XBox One with separately available USB3/Power adapter, besides the  Microsoft online store many places like Amazon and local game stores also sell these.
Kinect for Windows v2 (now fully replaced by the functionally identical Kinect for XBox One sensor).

Orbbec Asta & Astra Pro sensors are also supported. (Persee sensors not supported)

Intel RealSense S200, F200, SR300, ZR300, D415 and D435 sensors.


  • Does this work with the Kinect for XBox360 or Kinect for Windows v1 sensor?

No, please have a look at Pro Body, Pro Face and Pro PointCloud


  • Can I install this alongside the other Brekel Pro or Brekel (free) applications

Yes, the Kinect v2 sensor uses completely separate drivers so installing it will not interfere at all.


  • Does this new v2 sensor physically interfere with a Kinect v1 or Leap Motion sensor

Nope there seems to be no interference.
The 3 sensor technologies use slightly different InfraRed light frequencies to do their depth measurement and can therefore be used together.


  • Does this work on Windows 7 or XP?

Unfortunately no.
The Kinect v2 drivers need the completely rewritten USB 3.0 stack from Windows 8/8.1 provided by Microsoft.
With Windows 7 USB 3.0 support was left to the manufacturers and high bandwidth devices prove to be too unstable.


  • Why do I need a Intel or Renesas USB 3.0 controller, does it work with other brands?

These are the officially supported chipsets by the Microsoft drivers, they are proven to be able to handle the high bandwidth requirements robustly.
Support for other chipsets may be added in the future but may likely be unstable or not work at all.


  • Why do I need a DirectX11 capable graphics card?

The drivers convert the raw Infra Red video stream on the GPU to ensure realtime performance, this is based on DirectX11 DirectCompute code.


  • Does this software support multiple sensors on the same machine?

In fact this is a hardware limitation.
Due to the high bandwidth requirements of the sensor the limiting factor is the PCI bus speed of most computers.


  • Does this software support multiple sensors on multiple machines?

I am experimenting with this (you can find some posts about it in the blog) but this is currently in an internal pre-alpha state.
Keep an eye on this webpage and social media streams for future announcements if/when this will become an add-on module.

However all Brekel software has a “Record Triggering” feature which allows synced recording across multiple apps on one or more machines.
So yes you can record simultaneously using multiple sensors, but the software doesn’t automatically fuse the data.


  • How much better is this compared to the v1 software?

Depth measurement is based on a different principle than the previous generation Kinect and has about 3 times the fidelity.
Skeletons tracking now tracks 25 points (vs 20 on v1) on the body with more anatomically correct placement.
Due to the extra detail joint rotations can be calculated more accurately.
Skeleton data is in general less noisy than on the v1 sensors.
Up to 6 people can be tracked simultaneously (although the camera view will be pretty much filled).
The lenses have a wider field of view so a bigger area can be seen.


  • What is the minimum and maximum depth range a person can be tracked in?

Minimum: 0.5 meters
Maximum: 4.5 meters


  • Will this run on a Mac?

The software requires Windows 8/8.1/10 to run.
It has been confirmed to work well under BootCamp but will most probably not work under a Virtual Machine unless it fully supports DirectX11.

  • How can it be that the Kinect v2 sensor has lower resolution depth but is listed as having the highest detail?

The Kinect v2 uses a Time of Flight principle which produces a unique depth reading per pixel.

The other sensors use Structured Light and Stereo which produces depth values that are clustered in small groups of pixels, resulting in less detail in the produced pointcloud.
