Wireless Transmitter WT-2

We aimed to create the ultimate standard of utility.
In the process, we made control of shooting and transfer stress-free.

Can you to demonstrate how to use the WT-2?

Directions displayed on a camera monitor menu screen make connection simple.

Of course. Seeing the WT-2 actually operate is the best way to understand how convenient and useful it is. In preparing the WT-2 and camera, let's start by attaching the WT-2 to the bottom of the camera body. But first, make sure that the camera is turned off.

What about transfer methods?

Two modes are available; ad hoc mode for direct communication between camera and PC, and infrastructure mode using a wireless LAN access point as a relay point. Today, I will demonstrate the ad hoc mode using PTP/IP. The "connection wizard" makes connection settings between WT-2 and PC easy. Just enter the necessary items according to directions displayed on the menu screen. Would you mind omitting the details on PC operations and LAN?

Not at all. Please go ahead.

After confirming the wireless network connection for the PC to be used, turn on the camera attached to the WT-2. Select "Wireless LAN" from the camera setup menu, then, in "Communication Off" state, confirm that the mode is set to "PTP/IP."
Next, select the thumbnail button, which is the second button from the top left of the camera LCD monitor display, to activate connection wizard. Select the PC to be used as a destination on "Destination for the Wireless Connection," and the setup menu to enter the IP address will be displayed. Select automatic acquisition and press the ENTER button to get the IP address automatically. Settings for WT-2 and preparation for communication to PC are completed. The connection wizard makes it easy to prepare for the next step in connecting the camera and PC, and once the settings have been made, it's not necessary to repeat the procedures.
Now, I'll show you the process for pairing, the settings for connection between PC and camera. Set "Communication" of the wireless LAN menu displayed on the camera monitor to "ON," and wait a while. Look. The following message appears: "Running on PTP/IP mode. Waiting for the connection." You can check if the wireless link is active on PC, by starting the Wireless Connecting Utility and executing the "Adding Device" operation. This is simple enough for those who are not particularly knowledgeable about networks.


Next, let me take a picture using the Remote Camera Control function of "Nikon Capture 4 (version 4.2)", then transfer the picture data. Let's start by selecting the exposure mode. This time, I will use the Auto Multi Program mode. Look. Select the mode on the computer, and the setting shown on the camera monitor is made for Auto Multi Program mode. You can use the same procedure to select shutter speed and sensitivity. You can move the focus area, or adjust the image size and quality.

A battery indicator appears on the computer monitor, too.

Yes. When controlling a camera from a distance, you don't need the anxiety of not knowing how much battery life remains. As a final step, select the directory to save the image data from the download option menu. Now, all settings are completed. I will take a picture and transfer the data.

The data has already arrived on the computer!

Of course, transfer speed depends, more or less, on radio wave conditions. But normally, the level of speed that you just experienced should cause no problems.

Not at all. It is really practical.

The Wireless Transmitter is still in development.
The challenge remains to take its potential even further.

Microsoft Corporation aims to advance implementation of PTP/IP for transferring music and movie files. What do you think about the future of this protocol in the Wireless Transmitter?

Mr. Kawaji discusses how the wireless transmitter extends the potential for new developments in digital photography, including those for the COOLPIX series.

Speaking of wireless transfer function, there is a strong possibility that we may implement a function not only for SLR cameras but also for the COOLPIX series, so that more general consumers could enjoy it. Users could transfer data of party pictures, for example, to a computer. Then, guests at the same party could view the images on a big-screen monitor. The function can be used for various other scenes and situations.

Is it possible to build wireless transfer function into a camera?

It is still difficult, but could be possible in the future. The environment for using digital cameras is still in a period of transition. For example, new protocols for network access are pouring into the market. So I hope we come up with new ideas by developing technologies.

The pioneer in wireless transmitter development will keep challenging the industry for quite a while, won't it?

I think so. Wireless transfer technologies and usage are evolving, and we will continue to pursue the most convenient structure and style according to situation, from the user's perspective.

We will be on the lookout for upcoming developments in Wireless Transmitters.
Thank you very much!
