Pi as a video doorbell

Fri Oct 19, 2012 7:52 pm

Half-baked design for a Pi based video doorbell:

* Doorbell on the outside of the house wired directly to the GPIO pins.
* USB video camera powered by the Pi's USB port
* USB wifi to connect to my network
* Pi in case next to the door (basically immediately opposite the doorbell) with a power brick somehow run to it without pissing off the wife
* basic 8ohm speaker with basic amp circuit, powered off the Pi, tied to the 3.5mm jack, mounted hopefully inside the case
* some software to monitor the doorbell, start streaming video after a press, and of course send some sound out the speaker
* some software in my office in the basement to monitor the video stream, and to monitor the status of the doorbell... kind of envision a daemon that gets the doorbell signal from the Pi, starts up a VLC to watch the video and sound a "gong"
* some random thoughts of having the video camera always capturing, and streaming when motion is detected...

Two parts I am concerned about, without a Pi in my hands yet to experiment with:

* Can the Pi power the amp circuit, the video camera, the wifi dongle, and of course itself simultaneously?
* Any limitations on the sound? I keep hearing the 3.5 jack puts out crappy audio - don't know that I care for a doorbell sound, but it might be fun to have it shout out "Hey! There is someone at the door!"

General comments welcome! I've got parts on the way already... going to give this a shot.

Cheers,

j

If you get the right power supply (1 or 2A) you should have enough.
3.5 jack sound is OK for movies (slight low pitch hum) so it should be fine.
I have not tested myself but web cams seem to have issus with the rpi.

Check camera support beforehand , and gain knowledge on which exact setup it worked.

I have the "motion" program configured to email me a photo whenever movement is detected,
so I can see who's at the door - running a local email server makes the emails instant.

it also serves to show me who's been to the door while I'm out :D

relevant bit of /etc/motion/motion.conf:

Code: Select all

on_picture_save sendEmail -a %f -f myemail@hotmail.com -t myemail@hotmail.com -u "Webcam motion" -m "Motion detected." -s smtp.myisp.co.uk:25
