The majority of IP CCTV systems run over a LAN (Local Area Network). Understanding how a LAN works, how adding CCTV causes latency, and
what effect this will have on the existing data is a vital part of the pre-installation phase of networked CCTV.
How much bandwidth will a set of cameras need and how is this measured? How do you assess end-to-end latency and improve performance? How are CCTV images secured over a network? These and many more questions are answered in this in-depth course, involving both theory and hands-on work.
