Motion Detection with RaspiCam, Non-Module version

AnduriI

is it possible to use Motion to activate the screen and MMM-Facial-Recignition simultaneously? Maybe also use the on_event_start to activate some lights in the front of the MM to increase image quality…

bhepler

@AnduriI It should be. The motion system will operate independently of the mirror and only controls the signal running down the HDMI cable to the monitor. The Pi camera and the Magic Mirror process are still running.

If you create a simple python script to control the pinouts on the Pi, you should be able to switch on some simple LED lights to illuminate the front of the mirror.

Hello, I am a true n00b and I am having issues with your process for getting the Pi camera to work. I copied and pasted your first line exactly and I get the following.

What did I do wrong? Please help and thank you in advance.

@dam4
Are you running raspbian Jessie or Stretch?

Looks like the names where changed
Jessie: https://packages.debian.org/jessie/libmysqlclient-dev
Stretch: https://packages.debian.org/stretch/default-libmysqlclient-dev

dam4

@yawns I am pretty sure I am running Jessie. How do I know for sure?

yawns

@dam4
In the terminal run cat /etc/os-release

Maybe you need to run sudo cat /etc/os-release

@yawns
It looks like I am running stretch. This is what I get;

@dam4 I had the same problem and couldn’t get the correct dependencies resolved, but I just got it to work on stretch by following the Abbreviated Building Guide instructions here: http://htmlpreview.github.io/?https://github.com/Motion-Project/motion/blob/master/motion_guide.html

I had already tried the way you did so I had the motion.conf from the other build which I had modified, and it worked with that version.

edit:

sudo apt-get install autoconf automake build-essential pkgconf libtool libzip-dev libjpeg-dev git libavformat-dev libavcodec-dev libavutil-dev libswscale-dev libavdevice-dev
cd ~ 
git clone https://github.com/Motion-Project/motion.git 
cd motion 
autoreconf -fiv 
./configure 
make 
make install

@jasonarends
I just tried git clone https://github.com/Motion-Project/motion.git and it tells me this;

fatal: destination path ‘motion’ already exists and is not an empty directory.

I did a ls -al and it doesn’t show up as a directory. Should I remove the ‘motion’ that is in green from the home directory and try again?

I have to go to work so I will have to work on this tomorrow. Thank you for your help.

jasonarends

@dam4

yep, you have the original motion binary in your home directory still, you can just remove that.

dam4

@jasonarends
Thank you for your help. I have tried this and it seemed to install. The only thing I had an issue with was when I entered make install it would not create a directory and it failed. I then ran it as sudo make install and it seemed to install. I am running my MagicMirror now to see if it works. How long does it take to turn the monitor off? Again thank you for your help.

dam4

@jasonarends
How long does it take for the screen to blank out? So far the screen has stayed on and hasn’t even flickered. I have something in front of the Pi camera so it doesn’t pick up any movement and it has been over an hour now. Please help.

@dam4
Hi, make sure that you’ve edited your motion.conf file that it is using according to the instructions in the original post:

framerate 4 - run the detection video at 4 frames per second
threshold 2500 - increase the # of pixels to trigger the screen. We want them to get close to the mirror
minimum_motion_frames 2 - Motion must be detected in 2 consecutive frames (at 4 FPS)
event_gap 60 - This is important. This is how long in seconds after no motion the screen will turn off.
output_pictures off - Do not save images
ffmpeg_output_movies off - Do not record video
stream_port 0 - Turn off remote viewing
webcontrol_port 0 - Turn off HTTP control of camera
on_event_start vcgencmd display_power 1 - Important! This is the command to turn on the screen
on_event_end vcgencmd display_power 0 - Important! This is the command to turn off the screen

I’ve copied my config here: https://pastebin.com/61hiygKX (edit: updated conf)
If you put motion.conf in /etc/motion it should pick it up by default without having to specify anything.

Make sure you’ve set the event_gap, on_event_start, and on_event_end at the very least for testing.

You can also just try running the command

vcgencmd display_power 0

by itself to make sure the command works to turn off the monitor.

@jasonarends
My motion.conf is located in my home directory. I looked for /etc/motion and I don’t have a directory called motion in /etc. So I made one and put motion.conf in there. My screen still doesn’t shut off. I did look over my motion.conf file and all my settings were exactly like yours. I did follow all the steps at the beginning of this post. I can also type in vcgencmd display_power 0 and it turns off the monitor and vcgencmd display_power 1 turns it back on. This is really getting frustrating. Thank you for your help.

I also copied your updated_motion.conf.sh and double checked it and they match with the exception yours has a .sh at the end where mine does not. Is it supposed to have the .sh on the end of the file name or did it get added due to it being uploaded?

@dam4
Does your camera work outside of motion? Can you do

raspistill -o cam.jpg

and get a picture?

If so, try launching motion with:

/usr/local/bin/motion -c /etc/motion/motion.conf

just to be sure that it’s reading the correct file, and then if you can watch the output and paste it here (or pastebin if it’s large) it might help us troubleshoot.

Here’s what the first part of mine looks like with some of the config stuff cut out:

I did get a picture when I typed that in so I know my camera is working.

Here is the link to my config stuff.

config stuff

it sits there and my screen never blanked out, but I did notice that when I moved the block in front of the camera it did do something and when I put it back it did shut off the monitor.

jasonarends

@dam4 sounds like it might be working - especially based on these lines:

[1:ml1] [NTC] [ALL] motion_detected: Motion detected - starting event 1
display_power=1
...
[1:ml1] [NTC] [ALL] mlp_actions: End of event 1
display_power=0

I found a couple other config options and I think I was able to disable all the “event_newfile: File of type 2 saved to: /run/shm/lastsnap.jpg” stuff. I wonder if that’s what was causing memory leaks for @bhepler I set the pre_capture and post_capture to 0

You might need to play with some of the settings for threshold and event_gap to get it to behave like you want but it sounds like you’re almost there. I set mine up in pm2 like mentioned earlier in the thread and it’s been working fine for the last day for me.

dam4

@jasonarends
How would I set it up in pm2? I’d like to try it.

dam4

@jasonarends
I feel I am so close I followed the instructions exactly and I have motion started in pm2. it still doesn’t work. As I checked the motion-error-2.log I am seeing the following;

Error: Cannot find module '/home/pi/motion'

This is displayed over and over. I have checked for the directory /home/pi/motion and it is there. What am I missing?
