This article presents a system for monitoring the disabled or older persons developed from an existing surveillance system. The modularity and adaptability characteristics of the system allow an easy adaptation for a different purpose. The proposed system uses a network of sensors capable of motion detection that includes fall warning, identification of persons and a configurable control system which allows its use in different scenarios.<\/jats:p>","DOI":"10.3390\/s111110724","type":"journal-article","created":{"date-parts":[[2011,11,16]],"date-time":"2011-11-16T07:38:12Z","timestamp":1321429092000},"page":"10724-10737","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["A Configurable Sensor Network Applied to Ambient Assisted Living"],"prefix":"10.3390","volume":"11","author":[{"given":"Juan J.","family":"Villacorta","sequence":"first","affiliation":[{"name":"Departamento de Teor\u00eda de la Se\u00f1al y Comunicaciones e Ingenier\u00eda Telem\u00e1tica, Universidad de Valladolid, E.T.S.I.
