Which Should I Choose?

Analogue :: HD-TVI :: IP

Why not Ask the Expert?

CCTV technology has changed over the years since its inception
in the 1940s, electronics have become more advanced and more
compact each year and cameras are now commonplace in most
streets and businesses.

The early “noughties” saw cameras being mass produced with
colour electronics and a move from tape recording systems to
digital video recorders saving footage on hard drives.

Since that time picture resolutions and recording quality have all
improved but there has been little in terms of major changes in the
industry until the last three or four years.

First came the buzz word “IP” and now “HD” so

what does it all mean?

Analogue CCTV

Most CCTV systems you will see out and about are analogue CCTV cameras and analogue recording devices.
The “analogue” technology has been the CCTV staple for many years now and still is a perfectly adequate
technology for many installations where general surveillance is required. However Analogue lacks the stunning
high definition picture quality of HD and some IP CCTV systems. As many end-users are used to home HD TV at
home, HD CCTV is now being adopted by many installers to live up to end user expectations.
