oncise purpose	To alert the guard on the same event as the camera server.
Application type	Automatic, single picture.
Purpose	What is the use of having camera surveillance when nodbody is watching and can respond? Even if there is someone watching the event is bound to pass unnoticed accordingly to Murphy's law. Now the camera server can notify an application running on a computer over the network by sending a signal to a port on the computer.
Description	When the camera server encounters an event it takes a picture and sends it to a computer. Then it sends a message to a port on the same computer. On the computer a program receives the message and alerts the guard.
Configurations	Before you can use your Camera Server you have to configure its settings according to the manual, especially the TCP/IP settings. A script is needed for the Camera Server in order to find the servers. You must also make sure the camera has access to the ftp server on your network and that the server are properly configured. For instance, the Camera Server must have privileges to write data on the ftp server.
CRON Script	available
CRON script maker	available
FAQ	No questions registered.

Connections	The door switch should be connected to the Input Port 1. In this example the door is closed when the signal is low and open when the signal is high. To detect the door-opening event the signal must go from low to high. Auxiliary IO Port information available.
Component list	For demonstration purposes we used the following components: The Door Key locker PAVO from IKEA, 1 piece Simple on-off switch of type V of the brand Patterson, 1 piece 9-pin male D-sub, 1 piece 2-wired cable, 0,5 m The Cable 9-pin female D-sub, 1 piece 8-pin male Mini-DIN, 1 piece 5-wired cable, 3 m The Camera Camera Server connected to computer network, 1 piece
*VB application*	A VB application (available) waits for an alert from the camera server and reacts on it. Alert message: This message tells the application that an entrance has occurred. The application draws attention by sounding a beep. Picture ready message: This message tells the application to load the newly upploaded image from the FTP directory. Settings FTP directory Where the uploaded image is on the system. Listening port Which port should the application listen to? The same as the camera server sends alerts on. Alert message What the camera server sends when it has detected a new entrance. This message is sendt to the port specified in the CRON script. Picture ready message What the camera server sends when it has uploaded the newly taken image so the application can show it.
Java application	The java application with its tighter security and more flexible design allows a safer implementation. The version using unrestricted network access available. The easy way to allow an applet unrestricted access (Reading from a socket and loading pictures from the net) is to use the appletviewer from the JDK. Start the appletviewer and select Properties in the applet menu. Set the Network access: to Unrestricted and you're done. If you are using Internet Explorer 4.0 you can configure it to allow Java network access: Choose Internet Options from the View menu of IE. Select the Security tab. Make sure the zone says Internet Zone and select Custom. Repeat 4-8 for Local Zone if you want to access any URL from an applet running locally. Click the Settings to the right of the Custom radio box. Page down to find Java Permissions and choose Custom. Click the Java Custom Settings button. Select the Edit Permissions tab. Find "Access to all Network Addresses" and enable it. OK all the way out. Quit and restart IE. Parameters lastshot_location: Where the image to display is, when the camera server sends Picture_ready_message. May be absolute or relative URL Startup_image Where the image to display at startup is. May be absolute or relative URL Port_number Which port to listen for ALERTs on. The same as in the CRON script. Alert_message The text the Camera Server sends when it want to alert the application. Picture_ready_message The text the Camera Server sends when the image is ready for viewing. BackgroundColor The color of the background (24-bit RGB number). TimeZone Overrides the local timezone to one of the following: MET, PST, GMT, ECT, EET, ART, EAT, MET, NET, PLT, IST, BST, VST, CTT, JST, ACT, AET, SST, NST, MIT, HST, AST, PST, PNT, MST, CST, EST, IET, PRT, CNT, AGT, BET or CAT. The version not requiring unrestricted network access The resticted versions and examples available. Parameters lastshot_location: Where the image to display is, when the camera server sends Picture_ready_message. Must be relative, the codebase, URL. Startup_image Where the image to display at startup is. Must be relative, the codebase, URL. Port_number Which port to listen for ALERTs on. The same as in the CRON script. Alert_message The text the Camera Server sends when it want to alert the application. Picture_ready_message The text the Camera Server sends when the image is ready for viewing. BackgroundColor The color of the background (24-bit RGB number). Testing the applets First start the applet. Then start a Telnet session to the computer running the applet, usually your machine (localhost or 127.0.0.1), and the port specified by the applet. Type the Alert_message Then close the connection Repeat step two to four for the Picture_ready_message Now a new picture should be displayed.
