Viewfinder is available on the App Store for iOS and on Google Play for Android devices.

QTM Remote

QTM Remote works as a remote trigger for QTM. It provides a simple remote control interface that allows:

– Start and stop captures.
– Set the duration of captures.
– Save captures.
– Add events.
– Batch capture support.

QTM Remote is available on the App Store for iOS and on Google Play for Android devices.


The Viewfinder & QTM Remote applications require a working Qualisys motion capture system and a computer with WLAN and Qualisys Track Manager version 2.5 or later. The Viewfinder and QTM Remote requires iOS 6 or later.


To connect to QTM you can either manually enter the IP-address or hostname of a computer running QTM, or you can pick a QTM server in the list of discovered hosts. Note that the QTM discovery mechanism only will find QTM servers on your local wireless network.
