Description
Die Erfindung betrifft das Gebiet der digitalen Videorecorder und insbesondere einen für die Haussicherheit verwendeten digitalen Videorecorder.The This invention relates to the field of digital video recorders, and more particularly one for the home security used digital video recorder.
Überwachungssysteme können für das Eigentum und das Leben der Menschen Sicherheit schaffen. Im Laufe des ununterbrochenen Fortschritts von Wissenschaft und Technik sind Vorrichtungen, die zunächst komplex und teuer waren, nun allmählich zu Produkten der Unterhaltungselektronik geworden. Überwachungsvorrichtungen, die ursprünglich in großen Institutionen oder militärischen Anlagen verwendet wurden, haben aufgrund des Fortschrittes in der Elektronik allmählich Eingang in häusliche Anwendungen gefunden, so dass normale Familien Sicherheitsschutzmechanismen mit einfachem Betrieb und wirtschaftlichem Preis nutzen können.monitoring systems can for the Property and the lives of people create security. In the course of of the uninterrupted progress of science and technology Devices first complex and expensive, have now gradually become consumer electronics products. Monitoring devices, the original in big Institutions or military installations have been used due to advances in electronics gradually Entrance in domestic Applications found so that normal families security protection mechanisms with simple operation and economical price.
Ein herkömmlicher digitaler Videorecorder zur Überwachung zeichnet ununterbrochen Bilder auf, die dann an eine Vorrichtung wie etwa ein Videoband oder ein Festplattenlaufwerk, eine CD-R, eine CD-RW, eine DVD-R oder eine DVD-RW eines Computers geschickt werden, um Videodaten zu speichern. Ein normales Videoband kann jedoch nur etwa 1000-mal aufnehmen, außerdem besitzt es nur eine geringe Speicherkapazität. Das Festplattenlaufwerk hat zwar eine große Speicherkapazität, die Anzahl der Lese-/Schreib-Zyklen ist jedoch kleiner als 1000. Die verschiedenen optischen Platten haben den Nachteil, dass sie nicht wiederbeschreibbar sind. Darüber hinaus sind die Vorrichtungen für optische Platten, die zum Lesen/Beschreiben optischer Platten erforderlich sind, komplex und teuer, so dass sie für die übliche Heimanwendung nicht geeignet sind. Daher ist der Einsatz digitaler Videorecorder in diesen Bereichen begrenzt.One conventional digital video recorder for monitoring continuously records images, which are then sent to a device such as a videotape or a hard disk drive, a CD-R, sent a CD-RW, DVD-R or DVD-RW from a computer to save video data. A normal videotape can However, only about 1000 times record, besides, it has only a small Storage capacity. Although the hard disk drive has a large storage capacity, the number of However, read / write cycles is less than 1000. The various Optical disks have the disadvantage that they are not rewritable are. About that In addition, the devices for optical disks required for reading / writing optical disks are, complex and expensive, so they do not work for the usual home are suitable. Therefore, the use of digital video recorders in limited to these areas.
