What you need

• 1: Raspberry Pi 3

What you need (cont)

• 2: Pi Camera Module (Noir)

What you need (cont)

• 3: PC/Laptop Windows with zenmap/ncat (for network streaming stuff) and mplayer (for video stuff) installed– Both are opensource and freeeeee

Step 1: setup the C&C

• First, find out your C&C PC’s ip– Open a terminal in windows and run ipconfig

– Remember the ip, this is what your raspi will connect to

Step 1: setup the C&C (Cont)

• Second, in the same terminal, run ncat to pipe the stream to mplayer– C:\Users\jon>ncat -l -p 2222 | "C:\Program Files (x86)\MPlayer for

Windows\mplayer.exe" -fps 200 -demuxer h264es –– The -demuxer h264es arguments decode the stream into mpeg 4

Step 2: setup the pi camera• Setup Camera

– There are tons of tutorials of how to setup pi camera, so I will not cover that. Just make sure it looks something like below.

– Also if possible, try to get an enclosure for the raspi camera. You don’t want it to die every time somebody sneezes at it

Step 2: setup the pi camera (cont)

• Test Camera by running this command in the terminal– raspivid -o heuheuheu.h264 -t 10000– omxplayer heuheuheu.h264

Step 3: profit!

• Now put it all together by running this command on the raspi camera– raspivid -t 0 -w 1280 -h 720 -hf -ih -fps 20 -o - | nc 192.168.1.4 -k -l -p 2222

The –t 0 argument means raspivid will basically run forever streamed on port 2222

It’s alive!• It’s working!

Bonus Points

• SOUND– The demo had no sound, due to lack of usb mic. It

can stream sound. Try it out as homework.

• NETWORK SPEED– For best live action speed, use a wireless router

that can transmit on the 5GHz band. 2000++ Mbps means no lag whatsoever!

Bonus Points (cont)• MULTIPLEXING CAMERA– It is possible to multiplex the camera, although

stability issue may arise.
