... MAKE YOUR NETWORK SMARTER Axis Technical Training Axis Camera Workshop Advanced Level Session 1 Design of complete surveillance for a given site •Choose appropriate equipment. •Calculate Storage, Bandwidth and CPU needs. •Calculate lens specifications. •Install the camera on a network. •Assign an IP Address and verify the setting. •Adjust lenses. •Install, configure and test surveillance software. Optical – Focal Length Formula for calculating the Focal Length Focal length (f) - The result of a calculation of size of picture we want and the distance to it, resulting in a value (f) that is telling us what lens vi need Optical – Focal Length example f =h x D H 1/3” CCD Distance D=5 m Width H=2 m Calculated lens f=12 mm D=5m H=8m Calculated lens f=3.0 mm Mr. ROTAKIN WWW.CENELEC.ORG Standard EN 0132-7 Rotakin guide-lines http://www.homeoffice.gov.uk/docs/or_manual.pdf Mao 60 x 50 pixels Appr. 30 pixels Compare to Rotakin standard Kaya 10% 20% Rolling’ compared to Rotakin 10% Computer generated beauty Licence plate recognition Character recognition Appr 70 pixels Session 2 External Devices, Internet considerations •Connect and configure Audio accessories and compare sound quality. •Connect and configure PTZ camera and use it in ACR. •Connect and configure W-LAN accessories and understand security aspects, measure bandwidth. •Configure DynDNS router and understand Internet connectivity possibilities with regards to camera. Session 3 HTTP commands, Web design •Understand camera HTTP commands. •Seek HTTP command in manual and use these. •Understand HTML structure. •Make own HTML Web page. •Construct own camera Web page on Web Server. •Construct own camera Web page placed in camera. •HI-HIT Web server HTTP command in URL URL address HTTP command with parameters ? = delimiter to parameters & = delimiter to the next parameter. Compression = 0 no compression Compression = 100 max compression HTTP I/O Check Input Activate Output Note: camera returns status -> web browser get white HTML commands http://www.w3.org/MarkUp/Guide/ <html> <head> <title>New Page 1</title> </head> <body> your code here </body> </html> HTML tags title>My first HTML document</title> <h1>An important heading</h1> <h2>A slightly less important heading</h2> <p>This is a paragraph.</p> <img src=“axis.jpg" width="200" height="150"> This a link to <a href=“my_page.html">My best page</a>. <font color="#FF0000">hello in red</font> <b> bold </b> <br> = new line Camera Web page 2. Right click on white area 1. Go to demo 3. Click Source Camera Web page HTML code Enter camera IP address You may change as you wish Only camera resolution to be given HI – HIT Web Server Thousands connections to Internet One FTP stream Read the entire manual on following link: http://www.axis.com/techsup/cam_servers/tech_notes/live_video_iis.htm HI –HIT configuration a) Configure Web Server Create the image directory on the Web server. Example: c:\inetpub\ftproot\live Create a Web Server alias (virtual directory) and use this as the image path in the Web page Example: http://[WebServer]/live/ Get the LiveImg.dll and copy it to the "execute" directory in your Web server file tree (typically c:\inetpub\wwwroot\cgi-bin if you are using Microsoft IIS/PWS). b) Configure Camera to FTP transfer HI – HIT modification of Camera stream Change these Parameters in your HTML code: path: The image path (i.e. /live/image.jpg). fps | fpm: Frames/second or frames/minute. duration: For how many seconds the images should be pushed to the client. timeout: The image feed stops after timeout seconds if the image has not been updated. Examples: Deliver 3 images/second during 60 seconds. Stop after 30 seconds if the image has not been updated (default parameter values): http://<web_server>/cgi-bin/liveimg.dll?path=/live/image.jpg
