UDP (UDP/IP) rather than TCP/IP... UDP (User Datagram Protocol) is a communications protocol that offers a limited amount of service when messages are exchanged between computers in a network that uses the Internet Protocol (IP). UDP is an alternative to the Transmission Control Protocol (TCP) and, together with IP, is sometimes referred to as UDP/IP. Like the Transmission Control Protocol, UDP uses the Internet Protocol to actually get a data unit (called a datagram) from one computer to another. Unlike TCP, however, UDP does not provide the service of dividing a message into packets (datagrams) and reassembling it at the other end. Specifically, UDP doesn't provide sequencing of the packets that the data arrives in. This means that the application program that uses UDP must be able to make sure that the entire message has arrived and is in the right order. Network applications that want to save processing time because they have very small data units to exchange (and therefore very little message reassembling to do) may prefer UDP to TCP. The Trivial File Transfer Protocol (TFTP) uses UDP instead of TCP. UDP provides two services not provided by the IP layer. It provides port numbers to help distinguish different user requests and, optionally, a checksum capability to verify that the data arrived intact. UDP is the basis for your WEB_CAM setup. That is to say, you do not care what you are sending. The viewer may care, but they have the solution if they are offended or can't deal with the media you are working with. Yes that is right, turn you off! On the other hand you are sending a stream. Like water running down hill, it will not stop until you cut off the stream at the top of the hill. Where it lands is not your problem. You simply place the stream in motion and hope someone stops to drink (partake in your video). So, do not try to understand UDP protocol. Set it up using the dedicated device application that your WEB-CAM and your router supports. In most all cases this will be WEBCAM32 and through a port like 8888. Why 8888 you ask, because most ISP routers are set to block PORT 80. So stream through 88 and you will be delivering your message to the Internet. Or at least you think so... K3HKR |

Setting a dedicated IP for your computer... This
is a simple procedure but you must be able to get the properties under
"My Network Places". The easy way is to "right click" on the Desk Top
icon for "My Network Places". Now that you have done that, you
will be in the Network Places directory where you should see your
network icon. This icon tells you that the connection is active or not
and it displays the LAN card or driver connection you are using. Select
LOCAL AREA NETWORK with your right mouse button and click properties, you should
see this image we display to the left. Remember that we want to
change the TCP/IP so we must highlight the Internet protocol by
selecting it with our mouse.After you have selected the protocol you then click on the Properties button. Caution, do not click on the Uninstall. Now you will see another dialog box popup. This is where you will change the IP settings. NOTE: If you do not have the "My Network Places" on your Desktop you can get to the properties by using the "control panel" where you click on "Network Connections" and then on "My network Places" located in the left hand side bar. The Control Panel is located along the right side of the START MENU. Now
note the Internet Protocol Properties window dialogue box. The
highlighted areas must be changed. Select "Use the following IP address"
this will deselect the automatic IP address that you get from your
router. Don't worry, your router won't care. But the WEB-CAM will...You must enter an address. But which one ?? Well that is easy. Since all local IP addresses are usually 192.168.0.0 to 192.168.250.250 you can select one like I did 192.168.1.150 up to .199, whatever. Just remember to keep the last segment above 150 and below 200. Most routers will handle 192.168.1. (1-250). so take something above 150 because other computers or printer ports will use segments 149 and below. Now enter the subnet mask just as you see it here. The "gateway" and the "DNS" must be that of the router. If the router responds to 192.168.1.0 then that is what you type into these segments. Note: 1 number then a DOT and 1 number and a DOT. [example] 192 DOT 168 DOT 1 DOT 150 is your dedicated computer address. Remember that number. Now click OK and close "My Network Places". You have set the IP address of your machine. Go out and test the Internet. Nothing has changed... Step one is complete. Now go talk to that router...or continue with our KISS segment below. KISS - Keep it simple stupid... The most frustrating thing on earth is to set out to do something bass-ackwards. The steps I outline here are for good reason. Don't ask why, simply take this chronological order and all should go well. Before the initial step is taken, think this out a little. STOP NOW, IF: (A) You are running a PIII 1 Gig CPU or slower. (B) You are on Dial-up, or use one of the so-called accelerators. DON'T ASK WHY, JUST BELIEVE ME, THE ABOVE CONNECTIONS WILL NOT DO THE JOB. (C) You do not have a router connected to a broad-band modem. YES, YOU MAY GET THE WEBCAM TO WORK, BUT WITHOUT A FIREWALL, LOOK-OUT !! (D) You do not understand TCPIP, UDP, PROTOCOLS and IP TRANSMISSION PORTS (E) You do not have your "router user manual" or you do not know your Global IP. YOU SHOULD TAKE TIME TO UNDERSTAND THE ABOVE BEFORE YOU CONTINUE. OK, are we ready ?? NOTE: the connection speed depends on 3 basics. DSL = fast download, but limited upload - CABLE = fast download, restricted uploads during peak periods - FIOS = fast download and fast upload, crank everything UP!!! Step (1) Purchase your WEB-CAM. There are several to choose from either on the net or from chain stores like Circuit City or Office Depot. Purchase a decent one around 50.00 or so. (a) Be sure you have at least 1 USB 2.0 port on your computer. USB 2.0 will be the fastest way to install and the least expensive investment for your camera. (c) IP cameras are the ultimate connection, but purchase smart, not all of these are the best choice for this application. Step (2) Before you install the CAMERA software, down-load WebCamXP software from the Internet. There are 2 versions to purchase, PRIVATE is all you need to go live on CAM RADIO. Make sure the CAMERA is not connected, and install the software. Step (3) Plug in the CAMERA and let XP find it, if you must install the driver CD do that but do not install any USB capture software. WebCamXP will do all that for you. TIP: You will not have access to the CAMERA if you allow other programs to use it first. You cannot use the CAMERA for Instant Messanger and WebCamXP at the same time. There will be a conflict and the first program to access your CAMERA must be WebCamXP. Step (4) Now, set your computer to use a STATIC IP for the router and the Internet. You can follow our technical pages here... Make sure you test the Internet for email and other traffic. If you do not see the Internet after making the change, you did something wrong. Go back and follow your steps. Step (5) Now you must test the CAMERA connection to WebCamXP software. The bar below is the tool bar for the PRIVATE version of the software. We will refer to it a few more times so take a look...first the SOURCES MONITOR. Click there and you should see your face in the preview window. If not, click on the THUMBNAIL window 1 (one) with your right mouse button and CONNECT SOURCE. If this confuses you, use the HELP SCREEN in WebCamXP. Step (6) Now that you are seeing the CAMERA, you are ready to broadcast. But the router is not! Consider WebCamXP as your transceiver and the router as your antenna. They must be connected properly. Not all routers are the same. If you go to www.portforward.com you will find a router page where several different routers and instructions are posted. This website is one of the most helpful places on the Internet for setting your UDP stream out of your computer and to the router for service through your Global Internet address. TIP: Go to the UDP information FAQ on this page to read and understand the UDP Internet Protocol. Step (7) So, you understand UDP and you know that it streams images and carries no error correction. UDP/IP simply displays a stream of images (called video) from your computer to the router. Where the PORT FORWARDING PROTOCOL (WEBCAM32) is set to stream UDP through a port that you create. This port may be 8080 or for Verizon, port 8888. Linksys and D-Link, for instance, should use 8080 and never be an issue, so keep this in mind when you set your PORT FORWARDING. To set PF you must talk to your router. Generally speaking the router will be located at http://198.162.1.1 If you click on this you may see your router login page. If not try http://198.162.1.0 in either case you should see a login page where you will be required to enter a username - ADMINISTRATOR or ADMIN for short and a password, that is basically PASSWORD. TIP: This is where you are on your own, because there are hundreds of different routers, I cannot dream of every possible combination to get you to the PORT FORWARDING PROTOCOL setup page. Step (8) I assume that you are into your router and have found the PORT FORWARDING setup. Choose WEBCAM32 or something like that (read your router manual) and add this protocol. Make sure that the router sees your computer dedicated IP and that the UDP port is 8080 or 8888. There are several such pages that look like the one I have posted in my Verizon technical article on this website. If everything is set correctly according to your router you may return to the WEB/BROADCAST tab in WebCamXp software. Step
(9) Click on the WEB/BROADCAST tab and look at the very top LH
corner form box. It should look like this. This is the Internal HTTP
server form. You ONLY use this form, no other settings on this page will
do you any good, so don't worry about them. Enter your GLOBAL INTERNET
address in the box and enter the PORT setting next. Click on the GREEN
ARROW and it will turn to a RED BOX. In the very bottom pane on the
website page you will see the IP address as a LINK to your page
on line @
http://71.177.145.32 If you click
on this link you should see your image in a dedicated window. If not,
don't be too bothered, because some routers will not deliver this back
to your computer, but simply place the stream on the Internet for you.
Step(A) You must be able to serve the stream to the Internet. You do this in a JAVASCRIPT code that will be added to a website or webpage on the Internet. Here is where we must warn you, not all ISP's like these things being done, so you may have a few hoops to jump through. If you already have a domain and a website, this is simple for you, but if you do not, I recommend you follow along in this manner. SETTING UP A DOMAIN: On the Internet go to www.namecheap.com here you can purchase your ham radio call as your domain name. You will request a search for your call sign. Example www.K3HKR.com and then you will follow the steps on-line. Name Cheap is a domain name server. It will, for 10.00 per year, park your domain and URL forward traffic for you. So you must enter your ADMINISTRATOR, TECHNICAL CONTACT, BILLING CONTACT. Enter your specifics into these forms and be sure that your personal information is correct as the ADMINISTRATOR and use the SAME for all other contacts. Now pay !! As soon as you have created an account with a username and password, you will be able to set up the DOMAIN URL FORWARDING for www. your call sign .com. Now place the GLOBAL ADDRESS into the URL FORWARDING form pages. It should look like this... After all of this...your WEB CAM shows up at www.yourcallsign.com:port number and you should be live with video. We will place a member page on www.camradio.net that points to that URL and displays your CAMERA. You control everything at your computer, with no hassle of updating or paying for a website and a DOMAIN NAME HOST company. Believe it or not we are enticing a lot of interested parties into listening on 3.820, and watching our members in their shacks, on the air, live. We can stream audio if we desire and allow non-amateur operators to listen to the conversation, however you will need something like the SignaLink USB interface to do this. So there are only a few who actually stream audio. And that would be only the receiver audio unless that OP ran with the MONITOR on. As you can see, there are no limitations, and the possibilities are endless. If you would like more information, please contact us here or on the air. I hope this "TO DO" list helps you set up your CAM RADIO site so you may join us in the fun on 3.820 at 0400 UTC Monday - Friday (and on weekends too). Thanks, the gang at www.camradio.net - K3HKR
