Re: Motion activated camera with mp3-player

That looks like a simple python script waiting for the pir motion detect signal on a GPIO pin, then starting a video recording using the pi camera module and raspivid, then waiting an adjustable time to play an mp3.

Re: remote control raspberry pi - ssh from other network

I would not have gone with upswift method, but if you log into one pi, can you use ftp or sftp to transfer files (data) from one pi to the other? (Assuming those pis are on the same LAN)

If you look at the reviews on Amazon you can see people buying ready made zigbee controllers and remotes. Then get a zigbee USB dongle for your pi and go from there.
