What is Onvif?
Open Network Video Interface Forum (ONVIF) is a global and open industry forum which uses global open standards for the interface of physical IP-based security products. This technology has great flexibility, and it’s so popular nowadays. In this section I will present how it works, what kind of benefits has it and how you can use it. Let me instroduce what advantages has an Onvif IP Camera and why can be useful if you turn your USB camera to this higher level.
How Onvif Works?
If you turn your webcam to Onvif technology with Camera SDK you will get more information about your camera. Let me intruduce the onvif higher level technology. This is the standard for how IP products can communicate with each other within video surveillance and other physical security areas. Onvif technology requires broadband Internet connection. If you follow the guide you will get a solution how can you reach you webcam over internet, with Onvif IP Server solution.
Further requirements depend on the Onvif service you wish to use. The standard is providing great solutions and features of the security area such as Pan-Tilt-Zoom control, alarm handling, video analytics etc.
What informations can you donwload if you use Onvif:
- IP configuration
- Device discovery
- Device management
- Media configuration
- Real time viewing
- Alarm handling
- PTZ control
- Video analytics
The alarm handling is a very important feature because if the IP camera detects motion the system reacts to this event. The sensitivity of motion detection is adjustable. When a detection has happened the system reacts with a predefined action: capturing image or video and uploading it to an FTP server or sending it as an e-mail. So you can set your webcam as an IP Camera if you jump the first step of the guide. I’m so excited, I’m looking forward to show you this solution! Let’s begin!

Step 1: STEP 1: Hardware Requirements
In this chapter I would like to show you what kind of hardware items need to install this project. I’m ensure you that it takes just a few minutes. Let’s start to check what hardware requirements will need to collect to establish and make this project. These hardware items are so important, please check the following lists.
· USB Webcamera (Get an USB webcam)
· Raspberry Pi (Get a Rasberry PI)
· USB hub (Get USB hub)
· Extra USB cable (for power supply)
· Keyboard, mouse (Get keyboard, mouse)
· 5V DC power supply (Get 5V DC adapter)
· Onvif-compliant camera SDK (such as Ozeki Camera SDK)
· Ethernet cable (Get Ethernet Cable)
Let’s start the project to get information about hardware items and start to connect them to each other.
Figure 1 – USB Webcam
First of all you need an USB Webcamera can be an ordinary USB camera which you have bought at shop. It can be your own choice. I offer to use camera which has a good resolution too. e.g. 640x480. If you want to use and take good images and streaming I offer you to choose a high resolution camera. We are using an ordinary high resolution usb webcamera.
Figure 2 - Raspberry Pi
At this project we will show you how can you use your Raspberry Pi and your USB camera connnect with Cameras SDK and provide Onvif solution. You can buy i tor order on the Internet. This device has a memory card and we stored linux operation system for Raspberry Pi . Figure 2.
Figure 3 - Canyon USB Hub
It also can be your choice. I’m sure that you choose an usb hub which has more ports for connections. If you want to connect keybord, mouse, webcamera and other devices, then it can be useful if you buy a hub which has more than 3 ports. In this example we use CANYON 4 port USB HUB as you seen at Figure 3.
Figure 4- USB Keyboard and Mouse
If you connect USB keyboard and mouse you can easily install drivers for the connection. If you have other solution you can use it. At this time we use USB Keybord and Mouse devices.
Figure 5 – DC adapter
You need an 5V DC Adapter. It will give power supply for Raspberry Pi and USB devices. It can be an ordinary device, you can buy it an electrical shop or on ebay. Figure 5.
Figure 6 – Ethernet cable
You will need an Ethernet cable to connect your Raspberry Pi to you local Area Network. It can be a Cat5 straight cable, (Figure 6) when you connect Raspberry Pi to your home router. I offer to choose a cable which has long enough from your router till to your Raspberry Pi device. If you bought a longer one you can create a shorter one with a crymper and a pin connector.
Now we if checked the hardware, let’s start to connect them to each other. It can be easy for you, just connect usb devices to the usb hub. You will need an extra usb cable to give power supply for Raspberry Pi . The next pictre below will show how you need to connect. You can check the connnection on Figure 7.
Figure 7 – Connect devices
If you have HDMI to VGA converter you can connect your device with a VGA monitor you can reach your Raspberry Pi view. So you connect your USB devices with USB hub and the DC Apater to the USB hub. Finally connect the hub with Raspberry Pi . You can check the final state at Figure 8.
Figure 8 – Raspberry Pi hardwarde connections
We have an other step is to connect your Raspberry Pi to your local network. You will need this step to install MJPEG stream package.
Connect your Raspberry Pi to Localhost
Before then we jump to STEP 3, you need to connect your Raspberry Pi to local network. You can do this with an Ethernet cable and a router. Just plug the Ethernet cable to Ethernet shield and your router. You can also see how can you connect Ethernet cable to shield at Figure 9.
Figure 9 - Connect Ethernet cable to Raspberry Pi
Let’s connect the Raspberry Pi with your router. In this sample we used a Linksys WRT54g router. It’s not an important member of the hardware requirements. You can use your own one. Just check that you have connect to the Internet. We need to connect Raspberry Pi to Ethernet 1 port. Figure 10.
Figure 10 - Connect Raspberry Pi to Lan network
After we have connected Raspberry Pi to router, check that your router connected to internet WAN connection and the power supply. It’s more important because at STEP 3 you will install the package from the internet which will need for establishing the connection. Please check your WAN cable has connected to WAN port of the router. Figure 11.
Figure 11 – Connect the router to WAN network
The next step will help to you how can you connect your Raspberry Pi with Ozeki Camera SDK and how can you use it with Onvif technology. Let’s continue the next step of this guide.
Step 2: STEP 2: Connect Raspberry Pi MJEG Streamer Package Install
At this step we will show you how can you install MJPEG streamer package at your Raspberry Pi . After you have started your Raspberry Pi , and connected to the local network please start a terminal. If you don’t have graphical interface you can easily install, just use apt-get install package_name. Besides that you need to establish Ethernet connection. You need to set up internet connection at /etc/network/interfaces file. If your router use DHCP service you need to install dinamic ip address. Not we set dinamic ip address to reach the Internet. Modify the interfaces file with nano or other text editor. Please add another row to the file.
$ iface eth0 inet dhcp
After the network settings, check the connect with ping command. E.g. ping google.com. If the connection is established you will receive packets. Now let’s start to install the MJEPG streamer package. Follow the steps and be carefull do not miss one of them.
First of all you have to log in to root mode. After you sign as root you can start to install MJPEG streamer. The following command installs the three libraries that MJPG-Streamer uses:
$ sudo apt-get install libjpeg8-dev imagemagick libv4l-dev
The videodev.h header file that MJPG-Streamer needs you have to replace with a videodev2.h. You need to create a symbolic link to make MJPG-Streamer:
$ sudo ln -s /usr/include/linux/videodev2.h /usr/include/linux/videodev.h
The source code for MJPG-Streamer is available at sourceforge.net, please user wget command to find and to direct download the link:
After that you need to unzip the MJPG-Streamer source code. The source code download is a compressed zip file. You can put the file in your home directory and run the following command to extract the files:
$ unzip mjpg-streamer-code-182.zip
MJPG-Streamer downloads with several plugins the next command below only builds what's needed:
$ cd mjpg-streamer-code-182/mjpg-streamer
$ make mjpg_streamer input_file.so output_http.so
The following commands copy all the needed files into system directories:
$ sudo cp mjpg_streamer /usr/local/bin
$ sudo cp output_http.so input_file.so /usr/local/lib/
$ sudo cp -R www /usr/local/www
Let’s start the camera. We are almost reach your webcam. Be patiant it takes just a few seconds. Now it is time to start the camera module:
$ mkdir /tmp/stream
$ raspistill --nopreview -w 640 -h 480 -q 5 -o /tmp/stream/pic.jpg -tl 100 -t 9999999 -th 0:0:0
Start MJPG-Streamer. The camera is now writing images, so all that is left is to start MJPG-Streamer:
$ LD_LIBRARY_PATH=/usr/local/lib mjpg_streamer -i "input_file.so -f /tmp/stream -n pic.jpg" -o "output_http.so -w /usr/local/www"
Finally let’s start the service:
$ ./mjpg_streamer -i "./input_uvc.so" -o "./output_http.so -w ./www"
Figure 12- The service has started
You established the connection with your camera! Watch the Stream! Now you can connect with your web browser and watch the stream live. If you want to watch from another computer in your network use http://192.168.0.1:8080. You have to modify the IP address to your Raspberry Pi ’s ip address.
When you install this package at your Raspberry Pi , the streaming has started and you can reach it. Let’s check the camera view. You can check that stream is working, if you press the ip and port number 8080 into your browser. This is what you will see after installing MJPEG streamer in the browser. Please check and compare to the Figure 13 with your details.
