Off the top of my head there is two ways you can do this a more permanent solution and a temporary solution
Temporary: Speak to your phone company about obtaining a CDMA wireless network card and using that in your laptop to connect to the internet and stream/ftp the video using software such as Webcam-XP…perhaps use dyndns to register a dynamic ip against a free dyndns hostname.
CDMA Nic Card: ?
WebcamXP Software: $60
Dyndns – free
Permanent: Buy two wireless access points and connect big antennas to replace the little ones take them a mile apart and point them at each other….(line of sight)
Probably best to have someone who deals with service and support for radio communications help you hook these up.
And make sure you’re going to have the right equipment signal strenght etc…
2x Wireless Access Points – $200+
Antennas – ???
Radio Guys to make the coax lenghts etc unless you have the know how – ???
I’m guessing a CDMA wireless nic card would be the go to stream the capture up to the net…not sure on what the speed will be like but it should be ok?
