I recently used an IP-camera to monitor my garden. Now I want to expand with various sensors and a microphone module. Therefore I would use an Raspberry, the camera for the Pi and an USB microphone. The other pins are used for the sensors.
My problem is the communication with my with the PI. I would like to view and hear a live feed and also occasionally send status data (small ASCII file).
Since the PI has an Ethernet port, is it possible to send a live audio/video feed and data via cable (20m)? Is there a Linux based program to achieve this or do I need additional hardware/cabling?
