PAPERS4ALL: Ethernet based security system using Wiznet W5100

The need for Security systems have rapidly grown from being specialized for high-risk areas to be available and demanded rapidly by the average public. In the last ten years, small businesses have rapidly grown and expanded and the need of reliable, cheap and effective security system is becoming a must, not only for the business owners, but also at homes. One of the offered way of security systems offer the SMS notification service, nice but not that reliable. SMS center could have a congestion at the time the thief was sleeping in your company (or home) borders. Well another method of creating a security system and which would be very effective is to use the Internet or Ethernet Notification system. It is reliable, when using TCP, and effective where most internet services are always on demand and it is very rare, and very unlikely to have a sudden failure.

Unfortunately, this could be a little pricy since most embedded Ethernet devices cost a large amount of money and they are usually hard to deal with. That's why I was so interested and a little bit surprised with wiznet offering of the W5100 Hardwired TCP/IP Ethernet chip. I was so amazed of its various features especially the support for TCP and UDP protocols essential for an Ethernet based security system.

You can actually build a security system over the internet using an Ethernet device that would cost you about the same as any microcontroller. Simply amazing!

Unfortunately the document was lost in the net. So v r trying to upload it to a ftp server within two days... If any one in hurry mail us with ur id and v'll send u an softcopy of this project
