A Video Field Trip is facilitated by a device called a video codec. This equipment is basically a computer with software which takes live audio and video and compresses it into a format that can be sent over ISDN phone lines or the internet.
In addition to the video codec, a monitor, microphone, camera and usually a cart are needed to have a videoconference. Typically the camera and microphone are included with the video codec. Existing monitors, projectors and carts can be incorporated into a conferencing solution or this equipment can be purchased a package from a videoconferencing dealer.
Below are some examples of this type of equipment including a wall mounted plasma system, a cart on wheels with an LCD, and a codec/camera integrated unit.
