Motion Detector

[jdahli1]

@Hawking So running that command has the same result - nothing happens until I ctrl + c. I have been messing with the hdmi_* commands, but no luck so far.

[reaper81]

Can I use the Pi-Camera for Motion Detection and Face-Recognition at the same time or have I to use seperate cameras for each module?

This uses a pir-sensor

[bhepler]

@reaper81 You can use the same camera for both, but you’ll want to use a different module for motion detection. If you check out my posts, I put up a tutorial on using the PiCam for motion detection outside of the MirrorMirror framework. There’s no reason you can’t use my tutorial to get motion detection to turn your mirror display on and then the facial recognition module to switch the layout.

At least… no reason that I know of.

@jdahli1 Anyone have any thoughts as to what else to try? I have had no luck so far. Mirror continues to not turn back on randomly. Nothing I have changed so far seems to have worked. Any thoughts are appreciated.

Hello all,
I m totally new to Raspberry Pi and it’s an absolute miracle that I succeed to make it works and to add some modules .
So I feel sorry to ask and I beg your pardon if my request hurts some of you but can someone could explain me how to install this module ?
So far I’ve only installed the ones in the MichMich page (https://github.com/MichMich/MagicMirror/wiki/MagicMirror²-Modules)
Sorry again to ask but I’m so affraid to “break” my magic mirror which works fine now !
if I disturb let me know I will delete my post.

Thanks for your help

@Natacha3

cd ~/MagicMirror/modules 
git clone https://github.com/alexyak/motiondetector

In your config.js

{
  module: "motiondetector"
},

I think it would work, maybe…

[Natacha3]

Thank you so much Sean, I will try this at home tonight !
Thanks again for your patience and quick reply !

Suggestion:

Make a backup image of your mirror’s SD card.

You’ll sleep better. :^)

[j.e.f.f]

@Natacha3 I second @Mykle1 's suggestion to make a backup of your SD card, especially before you make any significant change. This way if you mess up the change, you can revert to your backup and try again. Furthermore, take another backup immediately after you are successful in implementing the new change. This way if you SD card becomes corrupt and unbootable (say due to a power outage, pulling the power cable without a proper shutdown, etc), you’ll have a fully up-to-date backup that you can restore in 30 minutes or so. This will save you many MANY tears.

[Natacha3]

So I’ve installed motion detector as Sean explained
I’ve modified the config.JS file, restarted the mirror but no change!

Is there something more to do to activate this function ?

• @Mykle1 and @j-e-f-f => I’ve done as you said: back up done! Thank your for your kind advice and … yes! I sleep better and I expect no tears now ;-)

[mongo116]

@Natacha3 I had issues with Motion Detector, so ended up installing motion alongside Magic Mirror and using that - https://github.com/Motion-Project/motion

[j.e.f.f]

@Natacha3 it took me a while to get my motion detector to work too. I suggest making a simple script independent of MagicMirror to test that your PIR sensor is working and tuned correctly. Mine has two adjustment screws on it that I needed to play with before it behaved properly.

More information here:

[Natacha3]

@j.e.f.f Thank you again Jeff but … I use a Pi camera, not a PIR sensor ! ;-)

I’ve checked that the camera was operating normally (sorry again, I’m not able to recover the link but … at least i’ve seen the picture !

[Natacha3]

@mongo116 Thank you for your advice but I’m a complete ignorant and I must admit that I’ve been affraid by reading https://github.com/Motion-Project/motion/blob/master/motion_guide.html

As a total noob, I guess it’s a bit out of reach for me. (maybe after 3 or 4 decades I will play the easy side with that ! ) ;-)

@Natacha3
I also tested the motiondetector of alexyak, without success and therefore installed Motion, which works without problems. However, I understand, that the process to compile it for your self is not easy for a beginner.
Are you aware of https://forum.magicmirror.builders/topic/988/motion-detection-with-raspicam-non-module-version
The linked thread provides a precompiled version of Motion and some recommended settings.

[Natacha3]

@Hawking Thank you so much for your input !
It works as a charm !

[trividar]

Hello all,
I updated my raspberry to stretch and now my MM disable the Monitor and the Monitor start immediate without motion. I got this massage:

Does someone know why this happen?
Thanks a lot!

[trividar]

No one an Idea?

[Natacha3]

Hi all,

I just come back on this topic because I followed the install process as described by hawking:

So I just open a command window and do the following command ./motion -c motion.conf
then I open another window and I start the MagicMirror with npm start

Everything works fine for a couple of hours then the Mirror stays dark

I do a CTRL Q
and in the motion window I get the following :

So I can see that some detection occured properly and pictures have been saved in /run/shm/lastsnap.jpg
(I checked, this function is deactivated but … anyway ! Only 1 pic is stored so it’s not a matter of folder flooded)

The Watchdog timeout would be a possible lead but google does not help me so much as so many different issues are linked… :cry:

I hope that you will forgive me if I asked a stupid question and what you will be rather indulgent not to turn me down !
