NEW - Understanding IP Multicasting
IP Multicasting is an extremely powerful feature of IP networks that allows CCTV video footage from the same camera to be efficiently viewed and recorded by multiple CCTV operators at the same time. IndigoVision is often asked by partners for advice on specifying and configuring networks to support IP Multicasting. This white paper explains how IP Multicasting works, when to use it and what features are required in network switches and routers. Example configurations are given for typical Cisco and 3Com switches... more
Understanding H.264 Video
This document provides a basic introduction, to all levels of reader, to H.264 Video, officially known as ISO/IEC 14496-10, in the context of the IndigoVision 9000 series. The document will introduce some of the basic concepts of H.264 video and show how they relate to the IndigoVision 9000 products. Some of the H.264 coding techniques will also be briefly discussed... more
Understanding Resolution & TVL
This document is aimed at the more advanced reader. It provides an introduction to the terms TVL and usable video resolution (not to be confused with sampling resolution eg 4SIF). The document also provides details of a practical way to measure the TVL performance of IndigoVision products along with the results achieved... more
Understanding Authentication
This document provides an introduction to the new authentication process provided with Control Center. When video is exported from an IndigoVision NVR the video is protected using a highly secure and well-known process such that any subsequent tampering, malicious or accidental, of the video can be detected. Using IndigoVision's File Player, which is provided along with Control Center, it is possible to authenticate the exported clip at any time to determine whether any such tampering has occurred... more
Understanding MPEG-4 Video
This document is aimed at all levels of reader. It introduces MPEG-4 Video, (officially known as ISO 14496-2) in the context of the IndigoVision 8000 MPEG-4 series. The document introduces some of the basic concepts of MPEG-4 video and shows how they relate to IndigoVision's 8000 products. Some of the MPEG-4 coding techniques are also discussed briefly... more
Understanding ACF
This document provides an introduction to the feature Activity Controlled Frame rate (ACF). ACF rate control provides a mechanism for drastically reducing the amount of required storage by significantly reducing the frame rate of the video during periods of inactivity but returning to normal frame rate immediately upon detection of activity... more
Understanding Analytics
This document provides an introduction to IndigoVision Analytics. The document covers the all-important process of qualification, configuration and a basic understanding of each of the different filter types. The document also examines common sources of false alarms, and how to significantly reduce their occurrence... more
Understanding Rate Control
This document is aimed at all levels of reader. It introduces the process of controlling the bitrate produced by a digital video encoder. It describes the rate control used by IndigoVision transmitter firmware and provides a set of recommended minimum bitrates to select based on motion and frame rate... more
Understanding Frame Rate
This document is aimed at all levels of reader. It introduces the effect of frame rate selection on video compression, with specific reference to stills-based codecs, such as MJPEG, and motion-based codecs, such as MPEG-4... more
Understanding Video Latency
This document provides an explanation and measurements of the ‘end-to-end’ system latency for IndigoVision 8000 series products. A description of the method used to determine system latency is also included along with the results achieved.... more
