## 树莓派3b++mjpg-streamer+usb摄像头实现低延时远程监控 ##

使用mjpg-streamer可以实现远程监控，mjpg-streamer的优点是图像清晰延迟小，比起motion延时那可是快了超级多

（注意最好是使用raspberry的源来安装会避免很多麻烦）

1.更新一下软件包

分两次输入

sudo apt-get update    
sudo apt-get upgrade

2.重启之后开启摄像头：

可以输入

sudo raspi-config然后选择 ‘5 interfacing options’中的‘camera’然后enable，之后树莓派将重启

3.检查摄像头是否被识别（两种方法）

将usb摄像头插到树莓派上，然后输入

ls /dev

发现有video0即摄像头被识别（如下图）

4.安装libjpeg库（用于解码）、imagemagick、cmake

sudo apt-get install libjpeg8-dev
    sudo apt-get install imagemagick
    sudo apt-get install cmake

5.下载并编译mjpg-streamer(需要做些等待)

wget https://github.com/jacksonliam/mjpg-streamer/archive/master.zip
    unzip master.zip
    cd ~/mjpg-streamer-master/mjpg-streamer-experimental
    sudo make clean all

6、.打开mjpg-streamer

cd ~/mjpg-streamer-master/mjpg-streamer-experimental
    ./mjpg_streamer -i "./input_uvc.so" -o "./output_http.so -w ./www"

能显示下面即为成功安装

7、打开网页查看视频监控

输入网址[http://树莓派ip:8080][http_ip_8080]
