High quality video and analysis
The VN415 performs real time analysis. Rapid data transfer (105 Hz binocular, 174 Hz monocular)
allows much more data to be analysed, giving very precise measurements and outstanding video.

Combi Goggles
The VN415/VO425 FireWire® VNG systems incorporate the industry’s leading goggle design.
The Combi goggle is light weight with a direct FireWire® connection to a laptop or desktop
computer. It has an easy fitting magnetic cover to allow for both occluded and unoccluded measurements and a built in fixation light to simplify testing. With adjustable mirrors and vertical,
horizontal and focus adjustments for each camera, the fit is ideal for all patients regardless
of skull size.
The disposable foam cushions allow a sanitary solution for each patient and provide a comfortable,
secure and light tight fit.

Video Recording
The video from each test can be recorded and stored in full on the associated storage device
(typically a hard drive) where it is linked to the results in the database record. The only limit to
the size of the recording is the capacity of the recording device.
When the session is reviewed, the recording will be available for replay in normal, fast or slow
mode. There is also the option to review the recording one beat at a time. The recording can be exported in AVI format for consultation or teaching purposes. Various sound file formats are available to include sound recording together with the video.
