Technology & Trends - Video servers (IP transmission)

The action of a voltage applied to a resistance element, draws power from the switch’s PoE port We often think about a power supply operating in a single format. A power source provides power to a device. You plug it into a wall outlet and that’s all that happens. PoE power is a far more complex. There is interaction between the source providing power and the device receiving power. This interaction is governed under the 802.3 AF and AT standards. These differences...

Understanding the complexities of the transform matrix In the concluding part of this 3-part review of the H.264 video compression standard, Kate Huber, Peter de Konink and Piet Nieuwets of Siqura discuss the transform, quantisation and entropy encoding - various block-encoding steps following motion estimation. Describing data in the transform matrix In contrast to the motion estimation step, the transform phase in the encoding process is relatively similar in H.2...

Image quality is affected by more than just zoom Surveillance cameras are only as useful as the quality of images they produce.  Therefore when selecting cameras for a security system, it is imperative to select one with features that will provide the best results possible.  It is often thought that the higher the zoom, the better the quality of the images produced.  However, this is not always necessarily the case. Phil Doyle, Regional Director, Northern Europe...
