What is the IRCam XTR?
The IRCam XTR is a bespoke head-tracking camera for use in any pc simulator that accepts inputs from Opentrack or Trackir software. It utilizes the OV9281 Global Shutter 120hz sensor, Varifocus 2.8-12mm zoomable lens, and a 850nm Infrared bandpass filter sealed behind an glass watchface. The hardware is enclosed in a stylized housing that matches the aesthetic of the IRTrackStar v5 XtremeTrak. And connects to your pc using an included 6ft USB cable.
Included Mounting Solution
The included mounting system utilizes a bespoke monitor clip and tail design that is compatible with a wide range of monitors including large format screens of varying thickness (thin screens up to thick 75in+ TV screens), as well as curved ultrawide screens of any size. An included adjustable ball joint connects the IRCam to the monitor clip for user friendly and stable adjustments. 4.5 inches of clearance is needed above top of monitor.
Optional Mounting Solutions (purchased separately)
The camera housing incorporates a 1/4-20 threaded insert, making it compatible with any standard webcam mount that utilizes a 1/4-20 mounting bolt (purchased separately), which provides the ability to attach the IRCam XTR to attach to desk mounts or clamped adjustable booms for connecting to sim rigs. There are numerous webcam mounting options on the market to suit a wide range of mounting needs if the included monitor clip isn't suited to your rig. Just be sure your chosen mount and mounting surface are solid so that the camera isn't being jostled while in use.
Usable Range
The IRCam XTR has a usable tracking range of 2ft to 6ft. If your screen doesn't fit within that range, you have the ability to use a wide range of webcam mounts to attach the IRCam to something other than your screen to achieve the proper range. (see above)
Requirements
The IRTrackStar XtremeTrak LED Clip is required. Also required is the free to download Opentrack software located here: https://github.com/opentrack/opentrack. The IRTrackStar TR (Trackir variant) can be used with some notable considerations; to use the TR version with its central led offset, Roll and Z axis must be disabled in Opentrack, and there will still be a slight pitching during yaw movements. I highly recommend the XtremeTrak version of the IRTrackStar for full fidelity 6dof.
The IRCam XTR gets approx. 100 to 115 fps in Opentrack with a USB C to C high speed data cable (not included), or approx. 80-90fps with the included USB C to A cable. The included cable provides more than enough fps for smooth tracking, and I opted for that as the included cable to avoid issues with USB C ports not being available on all motherboards. However, a high quality, high bandwidth, C to C cable will provide about a 20fps boost. (fps is dependent on pc specs as well)
You can bundle the IRCam XTR with the IRTrackStar XtremeTrak using the drop down above. It can also be purchased separately here: https://rjsimtech.etsy.com/listing/4472509095/irtrackstar-v5-xtremetrak. Even if you bundle them, do head over to the IRTrackStar listing and read it's product description.
Future Software Package
I am working on a bespoke version of Opentrack that will be called XtremeTrak, which will remain open-source and be compatible with a wider range of cameras and clips beyond just RJSimTech gear. XtremeTrak will focus on solving depth calculations for offset central led clips, correct issues with camera settings persistence, and provide a modern UI. While an eta is not currently available on the software, XtremeTrak Alpha 1.0 should be available by the end of 2026.
Instructions
The IRCam XTR is a plug and play camera. Simply plug it into your USB C port on your pc, launch Opentrack, and then adjust settings in Opentrack.

Lead times are currently set at 6 to 10 weeks. Partially due to being a new product, it'll take me some time to get quicker at building them. But many of the materials have long lead times so I have to maintain a buffer so I don't get backup up by delayed shipments. Production will be ramping up though, so lead times will come down.
