[ANSWERED: NO] Is there a decent Motion detection possible with Linux and a webcam ?

[Menard]

Application in the Mint repositories

Code: Select all

motion --help
motion: invalid option -- '-'
motion Version 4.2.2, Copyright 2000-2019 Jeroen Vreeken/Folkert van Heusden/Kenneth Lavrsen/Motion-Project maintainers

Home page :	 https://motion-project.github.io/ 

usage:	motion [options]


Possible options:

-b			Run in background (daemon) mode.
-n			Run in non-daemon mode.
-s			Run in setup mode.
-c config		Full path and filename of config file.
-d level		Log level (1-9) (EMG, ALR, CRT, ERR, WRN, NTC, INF, DBG, ALL). default: 6 / NTC.
-k type			Type of log (COR, STR, ENC, NET, DBL, EVT, TRK, VID, ALL). default: ALL.
-p process_id_file	Full path and filename of process id file (pid file).
-l log file 		Full path and filename of log file.
-m			Disable motion detection at startup.
-h			Show this screen.

Motion is configured using a config file only. If none is supplied,
it will read motion.conf from current directory, ~/.motion or /etc/motion.

They are kind but they forget to tell how to stop it, how to really shut it down
(because when you are here you can trigger a big number of videos of you moving... and it is also a security threat because you must start this application with sudo and let open, and if internet is connected ... possible problem )

In addition, another problem is that when I edit the config file to place the folder on another partition (NTFS) it doesn't work, as when it is anywhere on home partition it works, what's this problem ?

[nooblinx]

just kill process:

Code: Select all

sudo killall -9 /usr/bin/motion

[Menard]

just kill process:

Code: Select all

sudo killall -9 /usr/bin/motion

If there was a process, I could kill it in the gnome-system-monitor but I ve tried by ending the service but when killed it carries on to capture ... and the light stays on on the webcam

[nooblinx]

just kill process:

Code: Select all

sudo killall -9 /usr/bin/motion

If there was a process, I could kill it in the gnome-system-monitor but I ve tried by ending the service but when killed it carries on to capture ... and the light stays on on the webcam

I disabled startup service and manually start/end process myself:

sudo systemctl disable motion

startmotion.sh

Code: Select all

#!/bin/bash
sudo /usr/bin/motion  $@

and
stopmotion.sh

Code: Select all

#!/bin/bash
sudo killall -9 /usr/bin/motion

OK, so there is no decent Motion detection on linux ... thanks

We have not to make the job of the people who build applications

Just read the documentation on motion: https://motion-project.github.io/motion ... up_service
motion can be started and stopped normally as a program.

In motion.conf:

Code: Select all

# Start in daemon (background) mode and release terminal
daemon off

According to your explanation motion is running as a service. Then of course you can't just stop motion. For that you use systemctl:
Start the Motion service:

Code: Select all

sudo systemctl start motion

Stop the Motion service:

Code: Select all

sudo systemctl stop motion

Start the Motion service:

Code: Select all

sudo systemctl start motion

Stop the Motion service:

Code: Select all

sudo systemctl stop motion

That's what I had done when I wrote "I ve tried by ending the service but when killed, it carries on to capture" but wait ... I ve just tried it another time and that seems to work ... I suppose this, the other time I had close the motion's terminal before to kill this service by systemctl, it can be an explanation
But anyway we are told here, not to use sudo .. and here I ll had to use sudo to start motion and to shut down motion, so 4 times a day

[Menard]

Today,

Code: Select all

sudo systemctl stop motion

doesn't work anymore ...
My conclusion still will be : nothing works on Linux

nothing works on Linux
