25 April 2019 – CCTV Security

Last night’s presentation was all about CCTV security systems for use in both commercial and domestic situations.

John brought a selection cameras and storage systems which use the latest technology.

These systems include the use of Internet Protocol controlled cameras of various types enabling users to monitor their premises in colour with controllability enabling panning and zooming in on specific situations.

Other cameras use coaxial cabling, which relies on having a local power source, while the IP network provides power to the cameras up to 100 metres.

Normal monitors enable the images to be seen and computer based storage devices enable up to 15 terabyte of data to be stored.

Members had several questions relating to what effect there would be on radio systems and noise from powers sources.

All in all an interesting evening.
