System requirements: Positional tracking technologies
On this page you can find the system requirements for all positional tracking technologies supported by Varjo headsets.
Varjo inside-out tracking
Varjo inside-out tracking is available for XR-4, and Varjo inside-out tracking (Beta) is available for XR-3.
With Varjo inside-out tracking, the positional tracking cameras on your headset scan the room to keep track of your position. No additional accessories are required.
Note that to use OpenVR applications (such as SteamVR apps) with XR-4, you need to install SteamVR software.
With XR-3, OpenVR applications can only be used with SteamVR™ Tracking.
SteamVR™ Tracking
SteamVR™ Tracking is available for XR-4 base station tracking versions, XR-3, VR-3, Aero, VR-2 Pro, VR-2, XR-1 Developer Edition, and VR-1.
When using SteamVR™ Tracking, SteamVR™ base stations are used to track your headset and controllers. You can use either SteamVR™ 2.0 or 1.0 base stations for tracking.

| Base station model | Compatible accessories | Notes |
| 2.0 (recommended) | VIVE controllers (blue) VIVE Trackers (blue) Valve Index “Knuckles” Controllers |
Up to four base stations can be connected simultaneously.
