Hello Community,
I'm very bit confusing on what is the best solution for have a long range communication.
At first instant the main requirement is to achieve a 1Km, outdoor with possible little bit obstacle like tree or like of that,communication between a transmitter and receiver connected to the respective arduino Mega with baud rate useful for send/receive command/message.

Natures warning sign, if this were cheap/easy, you would already see a lot of people implementing it.
What are you trying to transmit?
Those kits are for transmitting 4 bit nibbles at a very low data rate.
They are usually for remote control applications.
As for the range , like most cases its totally dependant on whats in the way between the transmitter and receiver.
Those 433 Mhz modules are uni directional and not suitable at all for video streaming due to their low data rate.
Look at an Xbee or NRF24l01, as both as bi directional, but video streaming is still a tuff ask.
If one end is a computer then a HM-TRP pair (one having a USB interface) is the way to go. These are frequently used for UAV "telemetry" so you'll have no problem finding comments on their range if you do a little searching.
Personally I think XBees are a bad route to take: They're expensive, the Zigbee protocols are overly complex, and they're already outdated with the eruption in cheaper WiFi solutions.
