The WiPics transmitter
was originally concieved as part of an electrical engineering thesis project by RIT
student Dave Rea
. An early version
was shown of at the 2003 PMA tradeshow. The device finnally shipped
in 2005 with a very different design than the early prototype.
is currently the only aftermarket device of its type. While the transmitters
manufactured by both Nikon and Canon are designed to work with a specific group of their own cameras, this transmitter
will function with any camera supporting Compactflash
memory cards. As such, it is currently the only option for photographers using other types of digital cameras.
The WiPics transmitter can be configured via the small LCD on it's top plate or via an integrated web server. When the later is used, the transmitter is connected to the user's network (usually via ethernet
) and settings can be dialed in via any web browser. Alternately, products like ITP
have automated mechanisms that can dial in these settings automatically. Once set up, the WiPics transmitter can send images via FTP
and/or store them on Compactflash
cards or an optional internal hard drive.

The WiPics is a belt mounted device that connects to cameras via a dumby Compactflash
card. Using this interface, the camera believes that the WiPics is a normal memory card and saves images directly to the device. Those images are then stored either on Compactflash
cards placed inside of the WiPics, or an optional hard drive. The device can then transmit images via 802.11g
or its ethernet
It is important to note that the WiPics device does not
have an internal power supply, so it is reliant on external battery packs to opperate. The WiPics device can, however, accept a wide range of voltages (from 6 to 24), so photographers have some flexibility in this matter.
In addition to the basic WiPics device, users can purchase the transmitter with a couple of factory-installed options. Firstly, the WiPics can be equipped with a 20GB internal hard drive to store large numbers of images on. This drive appears as a 20GB memory card to any FAT32
-capable camera so it provides much more capacity than conventional systems allow. Secondly, the WiPics can also be equipped with a bar code scanner that allows photographers to associate additional data with their digital images.
Due to its unique design, the WiPics can be used with a wide variety of different digital cameras. Any camera that can accept type II Compactflash
cards will be able to work with the WiPics transmitter. Note that to effectively use the hard drive option, however, the camera should have FAT32
support as it will not otherwise be able to access all of the available capacity.
