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
Get access to the latest features and updates with ARC Early Access edition. You'll have everything that's needed to unleash your robot's potential!
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.
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.
- 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.
Everytime I try using wifi to connect devices, they never work. I have very bad luck trying to connect devices with WIFI and I wouldn't be surprised if it happened again. If I can get a transmitter with enough frequency difference and many channels, would I be seeing much interference. Also the recieving end of the camera needs to output in AV cable to attach to the small LCD screen that I will be attatching to a box casing with the receiving XBee and possibly a reciever inside, with antennas sticking outside.
I like the idea of wifi, but I am really worried about it not working, and 650 ft wont be enough, that is 225 m. Only twice the distance of the EZ-B camera I already have. The idea is good, I understand your point with wifi channel separation, but at 225 m it isn't worth spending all that money. Plus I will still need an ad hoc adapter.
I think a transmitter with enough channel separation will be my best choice, as for I can get 1000 m out of them. The one that I have been looking at has the same frequency as XBee but also has 4 channels. I am not sure if that is enough though.
Here is something that I would consider, just the frequency might not let this one work. If I can find a similar product to this with a difference in frequencies but similar size, shape, etc, I would trust that it would work. Also here is the camera, which is very cheap.
I am really sorry but WIFI doesn't sound very satisfying, and outputting to a computer isn't going to help me out with the LCD screen issue.
Thanks for pointing me out to them, as well as notifying me that the connection between the two could effect one another (XBee and trasmitor). Do you think I will be safe with the one shown, or more frequency separation? If not, will a lower frequency XBee make it better or worse? (does it matter which device is higher or lower from 2.4GHz)

Another ZigBee 900 MHz with wire antenna

Both support 128 bit Encrypted link at 256kb serial link
Also here shows the ch and conflicts between them. If I change the ch to 25 (2.475 GHz) or 23 if what I buy is not new enough (2.465 GHz) I think I would be fine, as for it has no conflict. But Clearing this up would be good, will this be enough?
On the web site that I found the XBee has 25 channels that it can go on, And you can set it up to automatically go to available channels within the min and max range that you wish. If I set it up to stay a few channels above the transmitter (2.4GHz) Do you think I should be OK? As for the transmitter that I showed you is very small and has a 1000m range in a "Perfect World". But I know that it decreases dramatically as walls become a factor, that is partly why I want it high, as for i will be a fair distance but metal walls will be close by. It will mainly be outside but objects will be around it.
Basically I will be in a truck controlling my robot that is outside (truck has walls, and radio-waves (will shut it off)) my robot will drive across a smaller field to where a well site will be held. It then goes into a metal building and checks the H2S levels from my H2S monitor. If there is H2S, I encourage not to go in there, if levels are clear then it is OK to go and work in there.
Not that I want to police the forum and remind everyone to mark questions as complete when they are, but it would help out when you tick the box to show only posts that require assistance (there are over 4 pages, most of which no longer need assistance).
