XCAM2:
Really Remote Viewing
-- Owen Linderholm,

Digital video cameras for hooking
up to PCs were once a novelty gimmick. But rapid price drops,
videoconferencing and webcams changed all that. The X10 Xcam2 with
XRAYVision is a neat combo most useful for security applications and as a
webcam.

The camera itself is a small, flat, oval black box about two inches across
with a simple cylindrical lens on an adjustable attached mount. The box
also has a flat, square panel that can be rotated through many angles, and
this is the giveaway as to the unusual feature of the Xcam2: It is a
remote camera with a radio transceiver box to hook it up to the PC or a TV
monitor. It can transmit images up to 100 feet using a 2.4GHz signal,
although the distance goes down if the signal passes through many walls.
The oval shaped base can be stood flat on any surface or be screw-mounted
to the wall. The camera is also waterproof and can be mounted safely
outdoors.

The transceiver part of the camera is a larger (four by six by two inch)
box that has a larger, fully rotateable antenna. It also needs to be
plugged in to electrical power and comes with a full complement of video
and audio RCA jacks as well as a coax connector for hooking directly to a
TV without PC involvement. You can set the transceiver so that the signal
is received on channel 3 or 4 on a TV and you also get four settings on
both the camera and transceiver for the actual signal.

The transceiver hooks up to the PC via an RCA to USB converter that is
supplied. This ensures a high-speed connection for transmitting images to
the PC.
Installation was
simple. I installed the software and drivers and plugged the camera in.
The control software is intuitive and functional and it was easy to change
settings. The software is designed with two principal goals in mind. The
first is security applications. The camera can be set to automatically
capture a single frame every few seconds on the PC and store a log of
captured images. You can control how often it does this and the software
can even be set to switch between several cameras that are all within
range. The software also includes motion detection and can simply capture
on motion detection.

The second application is for using the Xcam2 as a webcam. You can rapidly
set it up so that captured images are available over the web and can be
integrated into web pages. The camera captures and transmits audio as well
as video, taking it potentially a step beyond existing simple webcam-type
cameras and making it even more useful for security.

Image quality wasn't great in our test, but that can partly be attributed
to a weak signal. You can capture up to 640 by 480 pixel images (with
interpolation) and save images as JPEG files which are pointed to from an
HTML page.

The bottom line is that this camera is most useful for exactly the
purposes for which it was designed. It is a great security tool for
looking at and recording incidents and it is also a great webcam that can
be set up anywhere near a PC, even outdoors. At $129, it isn't cheap, but
it certainly is convenient. However, if you are looking for better image
quality or the ability to videoconference, the Xcam2 is not a good choice.
