打造全自动监控系统OpenWrt+Motion+ffmpeg+msmtp+Mutt
准备好基于OpenWrt系统的软路由,USB摄像头(uvc),OpenWrt编译环境。
编译OpenWrt可看另外一篇文章,本章主要定制编译软件包及应用配置
$make menuconfig > Kernel modules > USB Support > kmod-usb-core > Kernel modules > Video Support > kmod-video-core > Kernel modules > Video Support > kmod-video-uvc > Multimedia > ffmpeg > Multimedia > motion > Mail > msmtp > Mail > mutt
编译系统,完成后系统会在<builddir>/bin/targets/YourPlatform/
$make -j1 V=s
既然是定制系统,我将以下调试好的配置文件放置在<builddir>\
files/etc/config/motion.conf files/etc/crontabs/root files/etc/init.sh files/etc/msmtprc files/etc/Muttrc
files/etc/rc.local
motion.conf配置文件需要根据实际情况改变
videodevice /dev/video0 #根据usb摄像头设备填写 v4l2_palette 8 # 'MJPEG' width 640 height 480 framerate 15 #每秒15帧 threshold 3000 #像素差异触发 event_gap 60 #静止60秒后结束事件 quality 85 #输出jpg质量 #ffmpeg_output_movies on #由于OpenWrt平台缺少libx264故无法自动调用ffmpeg转换成MP4 target_dir /mnt/sda3/motion/jpg #输出目录 stream_port 8080 #web监控端口 stream_quality 50 #web监控质量,减少带宽占用 stream_auth_method 1 # 1 = Basic authentication stream_authentication user:password stream_localhost off #允许非本地访问 on_event_start echo %Y%m%d'_'%H%M%S > /mnt/sda3/motion/detectedTime #记录事件监控时间重定向到文件,事件结束后会调用
on_event_end 'ffmpeg -pattern_type glob -r 15 -i '/mnt/sda3/motion/jpg/%v'-'%Y%m%d%H*.jpg' -b:v 800k -s 640x480 /mnt/sda3/motion/mp4/%v'-'%C.mp4; cd /mnt/sda3/motion/mp4/; echo %v'-'%C.mp4 > /mnt/sda3/motion/latestMp4; cd /mnt/sda3/motion/jpg/; tar zcf /mnt/sda3/motion/tarball/%v'-'%C.tar.gz %v'-'%Y%m%d%H*.jpg; rm -f %v'-'%Y%m%d%H*.jpg; echo check file $(cat /mnt/sda3/motion/latestMp4) | mutt -s "Detected motion at $(cat /mnt/sda3/motion/detectedTime)" -a "/mnt/sda3/motion/mp4/$(cat /mnt/sda3/motion/latestMp4)" -- your@mail.com' #监控事件结束后触发ffmpeg以每秒15帧,800k视频码率,640x480分辨率将事件的图片转换成视频,然后打包备份原始jpg,删除jpg零散文件,将MP4以附件的型式用mutt发送到指定邮箱。
files/etc/init.sh配置文件需要根据实际情况改变
#/bin/bash #create mutt and msmtp folder if [ ! -d "/tmp/mail/" ];then mkdir /tmp/mail;fi if [ ! -d "/tmp/mail/sent/" ];then mkdir /tmp/mail/sent;fi if [ ! -d "/tmp/mail/sent/tmp/" ];then mkdir /tmp/mail/sent/tmp;fi if [ ! -d "/tmp/mail/sent/new/" ];then mkdir /tmp/mail/sent/new;fi if [ ! -d "/tmp/mail/sent/cur/" ];then mkdir /tmp/mail/sent/cur;fi if [ ! -f "/tmp/mail/inbox" ];then touch /tmp/mail/inbox;fi #sent email when startup echo "$(logread)" | /usr/bin/mutt -s "router is start running" -- your@mail.com
files/etc/msmtprc 根据实际情况修改
# Set default values for all following accounts. defaults auth on tls on tls_starttls on tls_certcheck off logfile /tmp/mail/msmtp.log account outlook host smtp.office365.com port 587 from your@mail.com user your@mail.com password password
account default : outlook #如是微软outlook邮箱使用此配置即可
files/etc/Muttrc根据实际情况修改
set sendmail="/usr/bin/msmtp" set use_from=yes set from=your@mail.com set envelope_from=yes set send_charset="utf-8" set folder=/tmp/mail set mbox=+mbox set spoolfile=+inbox set record=+sent set postponed=+drafts
set mbox_type=Maildir
files/etc/rc.local 根据实际情况修改
# Put your custom commands here that should be executed once # the system init finished. By default this file does nothing. /etc/init.sh & #开机运行此脚本 /usr/bin/motion -c /etc/config/motion.conf -b & #开机后台运行motion
