This is a repository for a babycam using RaspberryPi and webcam with Python Django backend.
See https://www.linux-projects.org/uv4l/installation/ and https://youtu.be/5QAHlZoPlgI
curl https://www.linux-projects.org/listing/uv4l_repo/lpkey.asc | sudo apt-key add -
sudo nano /etc/apt/sources.list
Add following line
deb https://www.linux-projects.org/listing/uv4l_repo/raspbian/stretch stretch main
Update uv4l services
sudo apt-get update
sudo apt-get install uv4l uv4l-raspicam
sudo apt-get install uv4l-raspicam-extras uv4l-tc358743-extras uv4l-server uv4l-uvc uv4l-xscreen uv4l-mjpegstream uv4l-dummy uv4l-raspidisp
sudo apt-get install uv4l-webrtc
sudo apt-get install uv4l-demos
sudo apt-get install uv4l-xmpp-bridge
For video configuration, go to config file
sudo nano /etc/uv4l/uv4l-uvc.conf
And change or uncomment following lines. To get <bus> and <address>, use lsusb and find the webcam.
device-path = <bus>:<address>
server-option = --enable-webrtc=yes
server-option = --enable-webrtc-datachannels=yes
server-option = --webrtc-datachannel-label=uv4l
server-option = --webrtc-datachannel-socket=/tmp/uv4l.socket
server-option = --enable-webrtc-video=yes
server-option = --enable-webrtc-audio=yes
For audio configuration, create or change config file
sudo nano /etc/asound.conf
And add/change following lines. To get <card number>, use arecord -l.
pcm.!default {
type asym
playback.pcm "plug:hw:0"
capture.pcm "plug:dsnoop:<card number>"
}

-
Turn Raspberry Pi on and ensure microSD card is inserted that contians the Raspbian Jessie Linux Operating System (above setup).
-
Connect USB Keyboard, USB Mouse, and Monitor (through HDMI)
-
Connect Raspberry Pi to Internet on your local network :
- via Wifi (look for wlan0 below)
- via Ethernet (look for eth0 below)
-
Open up
Terminaland typeifconfig. You should see the following result:eth0 Link encap:Ethernet HWaddr b8:27:eb:49:e9:1d inet6 addr: fe80::20f:eaff:fe91:407/64 Scope:Link UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:532 errors:0 dropped:0 overruns:0 frame:0 TX packets:532 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1 RX bytes:42256 (41.2 KiB) TX bytes:42256 (41.2 KiB) wlan0 Link encap:Ethernet HWaddr b8:27:eb:1c:bc:48 inet addr:192.168.0.10 Bcast:192.168.0.255 Mask:255.255.255.0 inet6 addr: fe80::20f:eaff:fe91:407/64 Scope:Link inet6 addr: 2715:e000:3098:a900:c338:7e68:77c2:d3ce/64 Scope:Global UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:11842 errors:0 dropped:854 overruns:0 frame:0 TX packets:8365 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:11994051 (11.4 MiB) TX bytes:1072259 (1.0 MiB)You'll need to find this line

cd ~/
mkdir Dev && cd Dev
git clone https://github.com/Helferlein21963/babycam.git
cd babycam/
virtualenv . -p python3
source bin/activate
pip install -r requirements.txt
If a environment error occurs, check write permission. Try sudo chown -R <user> ~/Dev/babycam/.
Apache2 Settings:
sudo nano /etc/apache2/sites-available/000-default.conf
Note: If errors happen with below, just do the following and it will re-install apache:
sudo apt-get purge apache2 # removes apache2
