(sorry for my english below :)
I want to install a camera on my robot, and i want to know: what camera's
type best fo use.
I think that 2 types of camera is possibly for use: web-camera and
But this types of cameras operates different kind of data:
1) web-camera - digital data 352x288x24bit (30 fps), compressed video to
send it through USB 1.1 (1.5Mbit/s)
2) mini-videocamera: analog composite-videosignal
So, what kind of camera is best for use in hope to transfer videodata over
I'm unsure of your exact application or requirements (image
quality/FOV/etc) but relatively inexpensive wireless color and black and
white cameras are readily available in thwe 900mhz, 1.2ghz and 2.4ghz
frequencies (the latter might cause problems with other consumer items
that share this frequency). 433mhz video transmitters are also available
that don't cost too much; in the US, however, these will require an
amateur radio license, so check the applicable laws in your country of
Connect the receiver to a cheap framegrabber card on your computer to do
image processing, or directly to a monitor. One major advantage of
wireless cams over webcams is that the wireless cams often have a wider
FOV, which could be important in some applications.
Using a webcam with an onboard computer and transmitting images back via
802.11b (or a or g) would work well, but expect the images to eat a
significant amount of bandwidth at higher framerates if the video is not
If your robot already has a controller onboard capable of interfacing
with a webcam and supports a wireless LAN, you may find that a webcam is
the way to go. If not, consider a wireless camera. You could use either
a separate camera and transmitter, or choose a camera with the
transmitter already built in.
If you go the wireless route, avoid X10 cameras -- these are among the
worst performing cameras on the market.
