Upon entering the room for the first time you will hear alot of noise. This will most probably come from the rack where all the gadgets are placed. The fan noise from the network switches is the most prominent. All signals from the cameras and microphones goes through those switches and that generates alot of heat. The noise is unfortunate, but it cannot be alleviated. When you get past the noise you notice three screens. The first two are monitors that can show the video from all the cameras, four in the main studio and one in each of the pink and green rooms. The central control is the Crestron TSW-760-B-S panel. With this unit you select cameras and microphones, start the the recording and later stop it to transfer the finished recordings to the PC.

It is however recommended to use the Panasonic AW-RP50 to set up the cameras. The controller offers a lot more control an ability to fine tune the camera positions compared to the jerky motions from the touch panel. You still have to use the touch panel to select witch cameras that are showed on the monitors. And to save and recall presets.

If you are a normal researcher it should not be necessary for you to read this section. But some people might find the nitty gritty interesting.  The rack is the heart of the operations room. All the cameras send their signals over ethernet to the rack and the audio is also sent there as an analog signals witch is then sent to the cameras for embeding in the videostreams the N6123 DVR records the feeds and saves the files with one file per video feed.

The Control room

General information

The control room is the operation center of the audio-video system. From here, you can monitor and control what is going on in the three testing rooms (video studio, EEG room, Eye-tracker room). Each of the testing rooms has cameras and microphones installed. The video studio has four cameras (one camera positioned in each of four corners of the room), the eye-tracker and EEG room have 1 camera respectively. All cameras can be operated from the control room. All cameras will get the same audio mixed in their video files with minimal drifting between sound and video. If needed, audio can be recorded in isolation (no video) or separated from the video after collection by the lab engineer.

Audio-video system

The lab has a state-of-the-art audio-video system, which allows making customized recordings. All video, audio, and camera control systems are found on the recording computer (BigPC).

Detailed instructions on how to use the audio-video system can be found in the handbook. It is also available in printed form in the control room. Note that for data protection reasons, you are obligated to save and delete your recordings from the lab equipment after every lab visit.

Introduction and training

If you would like to use the audio-video system for the first time, get in touch with the lab manager or lab engineer. You will then make an appointment for a one-on-one visit where you will get a tour of the lab, get familiarized with the lab’s routines and code of conduct, and learn how to use the audio-video system. After successful training, you will get permission to use the audio-video system independently.

For specific questions about the audio-video system and technical difficulties first consult the handbook, and if that does not solve it, get in touch with the lab manager or lab engineer.

Visiting address

The control rooom is located in room 114 of the lab.
