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