wireless transmission of signals

I am working on a spy robot that is capable of transmitting videos to a remote user . It also has sensors to check the temperature, humidity , smoke at that place. How can i transmit signals from the sensors to a pc/laptop wordlessly?

Use numbers?

Don't spy on people. It's an intrusion of their privacy and it's not nice.

Use numbers?

LOL
