Hi friends, I am making a quadcopter and I want to have a live video streaming from a camera mounted on it to my laptop. What are the options that I have and what are the things I'll need to buy for it.
P.S. Suggest methods which require parts that are available in India coz I have to complete this before 10th nov for an event.

Regards

for connect to laptop use any usb tunercard 
for a sample

Thanks for the reply buddy. But I am looking for a cheaper solution where I can use a normal CCTV camera or a webcam and transmit it's video via a wifi module instead of using RC transmitter and receiver. Just like IP cameras wherein the video can directly be accessed from the wifi hotspot.

Then buy a IP camera.

Ok ok , then how much distance coverage you expecting?  

If you are looking for video streaming over WiFi that will be costlier than you think(for web cam + streamer or ipcam with WiFi ready made)
In a cost effective way you can use tinkered mr 3020 router + webcam to stream but that tinkering will take time.

or just look at this

but still need some work to connect to laptop because that have a sdi output and not recommended anyway
