Long Range Camera B/C Xbee'S Long Range

Skip to comments   Jump to end

Yes it is me again, posting about the XBee and camera connection. If you don't already know my issue you can see here. I thought I was just going to use that jpg camera to take pictures and use them to make video for ARC Software. But I found a much more efficient way to send video feed from long distances, if you watch this video here. Although these aren't the exact parts I am planning to use I am pretty sure I can go about it this way. I am still unsure if i should use audio to usb and connect it to my computer, or have a separate LCD screen to put beside my computer, to use as display.

The reason I have made a forum for this, though, is I want to know if you can connect the EZ-B camera through antenna to a similar transmitter? (might have to wire up an adapter from antenna to AV, unless they exist). I have found a transmitter that is quite small and affordable that can send video and audio as well as a camera with 640x480 that can connect to it. If the EZ-B camera can't connect to the transmitter I will just buy the camera, as for it also has 170 degree viewing angle, and is waterproof.

If anyone else finds a similar problem to the one I had, this would be the best solution, as for the setup will not cost much more than to buy the jpg camera and components.

Upgrade to ARC Pro

ARC Pro is more than a tool; it's a creative playground for robot enthusiasts, where you can turn your wildest ideas into reality.

I'd go for a rc FPV kit, there're often just wireless security camera's but then used in Rc planes or helicopters. Keep in mind that you don't transmit video on the same frequency as your EZ-B, you'll lose connection. Also check your local laws for the maximum transmitting power you are allowed to transmit on without a permit, you could get a fine.

I am a little confused here, are you referring that if they aren't on the same frequency you will lose connection, or if they are you will lose connection. Because both the transmitter I found and the camera pointed out by DJ Sures happen to be 2.GHz, the same as the XBee Pro I am planning to buy.

I like the Camera that DJ has shown me, but I don't so much like the price. The camera and transmitter that I have found so far total up to be $70, where as the long range camera and reciever are worth $170. I am not 100% sure where I am going to go with it so far, but if there is one thing I am curious about. When transmitters say they have 1W or 2W, etc, are they reffering to the watts of audio, or the watts of power? B/c the transmitter I found you can spend more for watts and I am not sure what they mean in watt.

Lastly, bundel0 in transmitting power, are you reffering to the radio waves, etc, or the power for transmitting. I have never heard of this law before so will make sure that I am ok. Thanks for pointing that out, if there is a limit then I could have been fined, although I doubt anyone here is smart enough to enforce those laws.

Touching on frequencies here , to have range AND also make sure that your channel does not overlap your xbee my personal recommendation would be a wireless IP camera. Using a analog camera that does not narrow its frequency to 10 mhz or less increments can overlap and overpower your xbee. Here's an example but there are lots.of awesome WiFi type long range camerashttp://item.mobileweb.ebay.com/viewitem?itemId=261192411593&cmd=VIDESC

I understand what you mean using an IP camera not to interfere with the XBee, but where I will be using it there will be no cell service or wifi, so it makes it hard to use one if they require internet, etc. The transmitter has 5 different channels, i am not sure if that can make a difference or not but if I get an XBee at a lower frequency will that make things worse or better. B/c I don't know of transmitters that work at 10mhz, the lowest I have seen is 800mhz.

But in this case do the frequencies than need to be as far apart from eachother not to interfere, or do they need to be as close as possible. It seems from what I have read here they need to be as far apart, but I am not 100% sure.

Do the IP cameras require internet in order for them to work? And to view them do you have to use internet browser? My plan was to use an LCD screen to view what the robot was seeing, and put it by my computer, that way I would have more space for my controllers, PWM, etc.

You can you an IP camera three ways. You can use the first two for an onsite video link.

  • Ad Hoc WiFi direct connection to WiFi adapter on the PC

  • WiFi passive through connection through a router.

  • WiFi to internet and viewed over internet through the web

If you want max range from a laptop you need to use a external WiFi adapter that has a external antenna to match the needed range of your camera. I'm referring to a direct connect ad hoc connection without a router in the mix.

What I was referring to about 10 mhz is channel separation. WiFi has 16 channels between 2400 and 2500 MHz. A WiFi based device will choose an available unused channel to avoid any interference.
