WT-4/WT-4A Wireless Transmitter.
An add-on product that
plugs into the USB connector and provides 802.11b or
802.11g wireless transmission from the camera to a properly
configured computer or wireless access point. In addition,
you can connect the WT-4 via cable to an Ethernet connector
on your computer. The difference between the two models
has to do with country regulations. The WT-4A is used in the
US and Canada, where fewer channels are supported, while
the WT-4 is used in Europe and Japan, where more channels
are supported. Beyond the additional channels, the
transmitters are identical. The WT-4 comes with a short WA-
S1 antenna that mounts directly onto the transmitter. The WT-
4 requires an EN-EL3e battery (not included). A carrying case
that can be mounted to the belt is included, as is a carrying
strap.
