Optitrack SDK,TrackIR5,precision grayscale

[Adun]

Good day!
I want to use precision grayscale tracking capabilities with TIR5
So using this command
// enable selective grayscale mode
var = (int)4;
camera->SetOption(NP_OPTION_VIDEO_TYPE, var);

I've got grayscale frame but w/o dots tracking output
so please tell me how can I enable automatic dot tracking in precision grayscale mode?
I use SDK Public Beta - Version 1.3.037 beta 1

The TrackIR 5 does not support the OptiTrack-V100 style precision grayscale processing mode (video type = 4). Instead it has a different high-resolution mode.

Here are the modes it supports :
* 0 (segment)
* 5 (high resolution)

To enable the high-res mode, use :
var = (int)5;
camera->SetOption(NP_OPTION_VIDEO_TYPE, var);

Thanx
but I can't find it in optitrack SDK manuals
