Found a lot of articles about how to setup USB Camera with raspberry Pi for streaming video. Everything went fine for except one thing, stream stops after 5-10 seconds. Camera indicator still on, but browser stops showing updates, just frozen picture. The problem was that by default motion saves video and snapshots to /var/lib/motion/ directory. And looks like motion doesn't have enough permissions to write into it. So the fix is very easy:
sudo chmod 77 /var/lib/motion.
Configuration:
Raspberry Pi3, USB Camera Logictech C300, micro SD 4Gb
How to install motion:
- sudo apt-get update
- sudo apt-get upgrade
- sudo apt-get install motion
In order to enable remote access and deamon, change these params:
- webcam_localhost off
- daemon on
sudo nano /etc/motion/motion.conf
To setup daemon, open
sudo nano /etc/default/motion
and set start_motion_daemon=yes
Now you start and stop service by using these commands:
- sudo service motion start
- sudo service motion stop
If camera is on and off, everything is set and running.
Camera can be access remotely via
<raspberryIP_address>:8081
