Motion software


motionEyeOS, hashed password

  • Summary of the setup (for some reason, the static ip does not work so a different way to find the IP is needed)
    • touch ssh
    • cp ~/Downloads/static_ip.conf . (optional)
    • cp ~/Downloads/wpa_supplicant.conf .
    • nano static_ip.conf (optional)
    • If I hook rpi zero w to an HDMI cable, I see starting wpa_supplicant takes a while. It took 2 min 15 sec to boot into motionEye OS.
    • The ip can be found by saying Net Analyzer (it'll show MEYE-XXXXXXXX) or the Fing app on iOS. Fing on iOS does not identify raspberry pi running Raspbian but the nmap can (sudo nmap -sP
    • The static ip can be set if we go to the Setup > Network page.

Hashed and peppered passwords

My motionEyeOS settings

  • motionEye: 0.39.2
  • Motion: 4.1.1
  • Service: samba=Off
  • Expert settings: GPU=128
  • Video devices: 800x600, video rotation=180, frame rate=10 (Pi Zero W), 1600x1200, video rotation=0, frame rate=15->10 (Pi 2B). Note: changing the video frame rate will immediately change the streaming frame rate. So we need to remember to modify the streaming frame rate. Using frame rate=20 will make the video pixeled.
  • Text overlay: Left=disabled
  • Video streaming: streaming frame rate=2, streaming quality=85%, streaming resolution=50%, streaming port=8082.
  • Still images: off
  • Movies: H.264/OMX (.mp4), movie quality=75%, Motion trigger, maximum movie length=120 seconds, Preserve movies=1 week
  • Motion detection: frame rate threshold=1%, auto noise detection, light switch detection=75%, motion gap=10, capture before=5, capture after=5, minimum motion frame=5 (or go 20 by default), Mask=on, Show frame changes=on.
  • Working schedule: On.


On Ubuntu install mediainfo and run mediainfo XXX.mp4 to see the metadata.

With 800x600 resolution and 6 FPS, 1 minute video uses 12.7 MB.


Monitor the USB storage from another computer

Note the $PATH is empty when we try to run a command in ssh.

$ ssh [email protected] date
Welcome to pizero2!
sh: date: No such file or directory
$ ssh myremoteserver 'echo $PATH'
Welcome to pizero2!

Suppose the USB drive is mounted on /data/media/sda1.

$ ssh [email protected] '/bin/ls -lh /data/media/sda1/2019-09-28 | /usr/bin/tail -n 1'

On my SD card,

  • /boot (/dev/mmcblk0p1, 30MB) is vfat
  • the rest partitions are all ext4

USB storage

  • Use a large capacity USB drive for storage (GParted formatted to ext4). It will be mounted to /data/media/sda1 in my case. So this is the path I need to enter for the 'Root Directory' under the 'File Storage' category.
  • For some reason, the external USB drive was not mounted but the data was still saved to microSD card. See this post USB drive not listed in File Storage dropdown. Unplug the USB drive and plug it in Ubuntu 18.04. Still cannot mount it with sudo mount -t ext4 /dev/sdb1 /mnt. The error message is "can't read superblock on /dev/sdb1". Use sudo fsck /dev/sdb1 command and it shows "Journal checksum error" (same error as I saw from dmesg.log log file in motioneyeos). It will ask to fix it. Answer "yes" a few times as needed and it will exit automatically. Now I can mount the USB drive in Ubuntu 18.04 and also have it recognized again in motioneyeos. In fact, fsck is available in motioneyeos too. It seems to be a good idea to run fsck periodically and send a message if something is wrong.
  • (5/6/2019) For some reason the images for some dates disappeared. In fact, the images are not lost after I fixed it on 5/10/2019.
  • (5/10/2019) I update motionEyeOS to the latest (20190427). However the samsung external USB drive can't be detected. mount command shows a superblock error. Plug the flash drive in Ubuntu and run "sudo fsck -yf /dev/sdd1". It shows an error. The error asks to get a new version of e2fsck. I follow the instruction here to do install the newest e2fsck. Run fsck again and something was fixed. Plug the drive into Raspi and the drive is recognized (df -h).
    $ sudo fsck -yf /dev/sdd1

    samsung: ***** FILE SYSTEM WAS MODIFIED *****
  • (7/11/2020) I update motionEyeOS to the latest (20200606). I also change the (Video Device) video resolution from 800x600 to 1280x720 (the frame rate looks the same).
  • (6/25/2022) Retire over 3 years old samsung 128GB usb drive. The drive is unstable in motionEye and cannot be detected in Ubuntu 20.04 OS. If I am not using a USB drive, I'll need to consider a powered usb hub if I want to connect an SSD.
  • (11/3/2022) Reboot failure. Cannot ping. After reboot, only see 3 raspberries without any text. Another boot will fix everything.
  • HDD lifespan is around 3-4 years. But if it used as a CCTV recorder, it will significantly shorten its life.
  • (11/16/2022)
    $ sudo fsck -yf /dev/sdb1
    fsck from util-linux 2.34

  • Originally SSDs were less suited to use in CCTV recorders as they had limited write cycles so their life was shortened very quickly when used continuously. There are now, however, new types of SSD that are designed for use in servers and other write intensive devices which makes them better suited to CCTV recorders. It is important when selecting an SSD for use in CCTV that it states it is for use in write intensive applications.

Storage: Network share

Log files

All are under /var/log directory.

  • motion.log
  • motioneye.log: useful to find out regularly if there are any errors. It would be good if we can scan this file every day and email if there is any ERROR in this file. See below for more info.
  • messages
  • boot.log: useful to find out the booting date/time from the history
  • dmesg.log
  • "dmesg -L -T" command to show the date/time

These files can be downloaded directly from the web interface (under "Expert Settings"). All except <messages.log> can be found in /var/log directory. The <messages.log> is coming from <messages> file in /data/log. PS. it seems /var/log and /data/log has the same contents.

Motioneyeos Webserver,MJPEG server and SSH don't respond after one day, ping still works on Raspberry PI Zero W

(11/4/2020). System has no response. Use "grep -i error FILENAME" to get some error messages. Still no clear answer to no response problem.

  • dmesg.log:
    • print_req_error: I/O error, dev sda, sector 0
    • EXT4-fs error (device sda1): ext4_find_entry:1455: inode #2: comm python: reading directory lblock 0
    • EXT4-fs error (device sda1): ext4_find_entry:1455: inode #2: comm ml1:FrontWindow: reading directory lblock 0
  • messages:

    • ERROR: failed to get config for remote camera 1 on Failed to connect to port 80: No route to host

(1/12/2021). System has no response (got an email notice from my another server's cron job which pings the motioneyeOS box every 6 hours). I am following this message to use crontab to schedule reboot every morning at 5AM.

  • grep $(date +%Y-%m-%d) /var/log/motioneye.log | grep ERROR | wc -l
  • cleanup_interval parameter (mine is 3600). See /data/etc/motioneye.conf. Follow the wiki, I change is to 43200 (12 hours/twice a day).
  • Maybe I should try to save files to a network shared folder?

(8/26/2021). System has no response. ping returns unreachable. ssh returns no route to host. Network Analyzer Pro does not show the IP. scp dmesg.log, motion.log, motioneye.log, boot.log and messages files back to investigation.

  • messages file shows the last message was 'user.notice throttlewatch: currently: ok, temperature: 47 C'. That happened when the system restarted. And it is the only message after the system restarted. The next message is supposed to be "user.notice date: current system date/time set to ...." and cron related messaages.
  • dmesg.log does not show any interesting message
  • motioneye.log does not show any interesting message
  • motion.log does not show any interesting message
  • boot.log does not show any interesting message
  • Change crontab to reboot on every Sunday instead of every day

Backup/restore settings

  • We can backup and restore the current settings
  • "motion.conf"
  • Getting a reboot loop problem on my 16GB microSD. It may be caused by using up the storage.
  • The Backup configuration file is called "motioneye-config.tar.gz". When we restore, it will ask to browse the file from the local drive.

Run a command

Motion trigger, Pi zero W

  • Threshold and mask. Hard to set up the motion trigger. #695
  • Pi zero. Motion trigger function on Pi zero is not stable even I set frame change threshold 0.1%. Ssh to Pi zero shows the CPU usage is consistently high (> 90%). Even "continuous recording" is not stable on Pi zero. This leaves only the streaming and interval snapshots for still images option for pi zero.
    • Still images. Capture mode: Motion trigger, Motion trigger (one picture), Interval snapshots, All frames, Manual.
    • There is a timelapse button under the "Open Picture Browser" window. The created timelapse video is in a avi format and downloaded automatically (check browser's setting if the download is blocked). Works fine on Pi zero. We change change the "snapshot interval" in seconds and increase the resolution.
  • 4:3 aspect ratio:
    • 800x600
    • 1024x768
    • 1280x960
    • 1440x1080
    • 1600*1200: 171 KB for a picture (or .6 GB per hour)
  • 16:9 aspect ratio
  • Table of actually frame rate depending on the resolution and target frame rate from my experiment (HW: Pi2):
resolution target fr 15 target fr 30
1600x1200 8.6
1280x1024 8.6
1280x720 11.65
1024x768 13 15
800x600 15 23.5
