The head restraint adapter (HRA) enables the camera to be put on top of the seat as a replacement of the head restraint. The HRA can be easily adapted to the various head restraint types. The camera located in this position is able to monitor the vehicle instruments. Due to the focal length of the standard lenses it is mandatory to use additional close up lenses the get a clear picture for this short distance.

The time lapse video recorder can record the video signals to hard disk. This will complete the testing documentation and facilitate the trouble shooting.
