PRemote-HD - The camel and the needle´s eye?
PRemote-HD: Transmission of HDTV and Megapixel streams at low bandwidths! Or: How does a camel pass through the eye of a needle?
The relentless drive for better picture quality and the trend towards megapixel and HD cameras have together brought about the enormous growth in the volumes of data generated when surveillance scenarios are recorded – and consequently the expansion of bandwidth needed to transmit the pictures. Anyone who is planning to set up a video network must therefore begin by answering the question: How can these enormous data volumes be transmitted? How can the load on the company network be reduced while still maintaining the highest level of data security?
PRemote-HD: Transmission of HDTV and Megapixel streams at low bandwidths!
With PRemote-HD Dallmeier has developed a special method that enables the transmission of HDTV streams even at low bandwidths.
PRemote-HD is a method developed by Dallmeier that uses transcoding to enable the transmission of HD and megapixel streams even at low bandwidths. PRemote-HD is particularly useful for locations where images need to be recorded at highest quality but have only a low-bandwidth network available, for example DSL networks with a 128 kbit upload.
As opposed to standard transmission methods such as Dual Streaming that allow users to only change quality settings for the transmission of live images, PRemote-HD also offers a bandwidth-saving transmission of recorded images. Therefore, it is not only possible to view live images, but also to evaluate recordings over great distances in highest resolution.
PRemote-HD furthermore enables so-called split streaming for SD cameras, i.e. a multi-split (up to 16x split) is transmitted in just one image. Consequently only one stream is necessary. It is possible to quickly and conveniently switch from split to single image with a mouse click.
Good to know: PRemote-HD not only supports Dallmeier cameras but also third-party IP cameras that are recorded via RTSP method in MJPEG or H.264 format.
SmartZoom is a very special kind of zoom functionality. With SmartZoom the relevant image area that is zoomed in (picture of interest) is cut out from total image (cropping). Only that image section is transmitted. Thereby the size of the image is reduced without changing its resolution. In other words, it is possible to achieve a higher resolution and thus higher richness of detail while the bit rate remains the same.
Later upgrades possible
PRemote-HD is available for Dallmeier DMS and DLS recorders as well as the VideoNetBox and Smatrix. It is possible to subsequently activate PRemote-HD on already purchased systems once they have been updated to the appropriate software version.
