Medien<\/a><\/p>\nF\u00fcr das MediaImage ben\u00f6tigt man einige Zeilen PHP. Anbei ein kleines Skript, das ein MediaImage anlegt, das zugeh\u00f6rige Bild von der Kamera l\u00e4dt und auch gleich einen Timer zum Refresh des Images anlegt.<\/p>\n
Als Konfigurationsparameter muss man die URL des Kamerabildes angeben. Diese URL findet man in der Dokumentation der Kamera oder im Internet.<\/p>\n

Lichtschalter mit automatischer Aktualisierung des Kamerabildes:<\/span><\/strong><\/p>\nAls zus\u00e4tzliche Option kann man sich auch noch einige Lichtschalter definieren, die bei einem Schaltvorgang des Lichtes automatisch das Bild der Kamera aktualisieren.<\/p>\n
Im Konfigurationsteil des Skriptes hinterlegt man einfach die ID des\u00a0Skriptes zum Aktualisieren des Kamera Bildes und die ID der Variable, die man schalten m\u00f6chte.<\/p>\n
Das Skript legt dann automatisch eine zus\u00e4tzliche Variable zum Schalten des Lichtes an und auch ein Event auf die urspr\u00fcngliche Variable um den Status immer aktuell zu halten.<\/p>\n
