OBJECTIVES
NEWI North East Wales Institute of Higher
Education

• Develop a Home Automation Remote System
• Use different inner and outer network
  technologies
• Use devices that are easy to install
• Use low-price materials and devices
• Make it suitable for inexperienced users or even
  disabled people
• Make it scalable for further add-ons
• Manage multiple control points
• Encourage standardization

WHY REMOTE CONTROL?
NEWI North East Wales Institute of Higher
Education

• Enables control from almost anywhere (more
  comfortable)
• Instant alerts greatly increase security
• Backup emergency control
• Optimal for people with reduced mobility
• It can be combined with local control to give
  higher flexibility.
• The network hierarchy has been rapidly moving
  lower in the chain towards smaller and more
  personal devices (Canosa, 2001)

Conclusion
NEWI North East Wales Institute of Higher
Education

• The E-home is coming quickly
• Standards are not completely established
• Remote Control is necessary for certain purposes
• Developing low-price systems will accelerate the
  process of turning our homes intelligent
• The price of the intelligence in a house in
  comparison with its body, is insignificant
