A question about This Remote Webcam Transmitter

3 posts in this topic

This is an example i found here in the forum, it's a WebCam Transmitter Via TCP... well, It's working perfectly, i modified it to send the photo as JPG file Not BMP so it makes it faster.... BUT:

I am using a Mobile BroadBand internet Device to connect to the internet.. and i pay for it monthly.. so if i used this WebCam Transmitter it seems that it sends data to a socket in my PC and the other people connect to my PC from their browser as: http://myipadress:6969/ ... so "AM I LOOSING PACKET DATA?" or we can say it's a free video call for me? :)

I hope you go what i mean, im sorry my English is not good enaugh. :)

You would have to check with your mobile supplier, but I think you will almost certainly pay for the data sent both ways - otherwise the mobile operator would be giving free data, which is against their business model!

Perhaps you could send the images to your website, or even a dropbox, and let others view them from there?

Thanks Willy :).. but sending the images to my website means "Uploading" :) .... means loosing data.

Seems that it is against their business model as you said. Posted Image:P
