Training: Bandwidth Basics for Video SurveillanceBy: John Honovich, Published on Apr 19, 2010
Bandwidth is a critical, yet under-emphasized aspect of video surveillance. While some suggest bandwidth is free and unlimited, real world IP video systems deal with bandwidth constraints regularly. If you are going to deploy a solution that is reliable and provides high quality video, understanding and ensuring sufficient bandwidth is critical.
Inside the Pro section, we provide a 20 minute video that explains the fundamentals of bandwidth, providing multiple examples of bandwidth 'in action'.
The video screencast should help you answer the following 18 questions:
- How much bandwidth is needed for a given video feed?
- How much bandwidth do you have in a given scenario?
- How do you measure bandwidth?
- What acronyms are used in measuring bandwidth?
- What's the difference between bits and bytes?
- What problem arises when bits and bytes are confused?
- What IT specialists prefer to use the term bits?
- What IT specialists prefer to use the term bytes?
- What is the least and most bandwidth that is generally available?
- Why is the 'symmetry' of bandwidth important?
- In what situations, would you have 'asymmetric' bandwidth?
- How much bandwidth is generally available inside an office?
- How much bandwidth is generally available going to someone's home?
- What's the difference between full and half duplex connections?
- What network types use half rather than full duplex measurements?
- What are the key drivers of IP camera bandwidth consumption?
- How much can bandwidth consumption vary for IP cameras?
- How do you know if you do not have enough bandwidth available?
