Abstract: Improvements to network switches and other network components that enable improved status monitoring and logging of network and device parameters, particularly for networked video surveillance applications. The network switch or other network component, which may be an IP camera for example, outputs a networked video stream which contains graphical representations of relevant data, such as simple graphs or indicators. The networked video stream, and therefore the relevant data, can then be conveniently viewed and/or stored as a networked video stream with existing standard technology. An additional benefit is that conventional motion detection can be performed on the graphical representations in the networked video stream to generate alarms or trigger events.

Abstract: An improved method and apparatus for data storage on hard disk drives (HDD) is described. The method and apparatus employ sequential data recording techniques ideal for sequential recording applications thus enabling the production of cheaper, more reliable and conveniently accessible systems. The sequential recording method may be employed with arrays of low-cost HDD and/or with the sequential employment of sectors, or groups of sectors, located within the individual HDDs themselves. An important feature of the system is that data are never deleted and so is only ever lost when overwritten with new data. Particular embodiments of the invention describe mirrored data storage systems which also provide for protection against data loss should one or more data storage elements fail.
