Our world faces greater security threats than ever before and governments and commercial organisations are investing heavily in the security and safety of assets and personnel.
OFFERING a range of practical safety solutions that have proved indispensable to first responders and investigators, the video surveillance industry is in the midst of a period of enormous expansion. New products and new surveillance solutions with improved performances and reliabilities are continuously appearing on the market. But having so many options leads installers and integrators to another problem.
Because of rapid and ongoing technological development, there is a great deal of uncertainty among security engineers over which technology or product is best in the long term. Ultimately, the final selection should be based on the fact that the chosen security solution is supposed to offer the best performance and value for money to our customers.
The aim of this article is to describe and compare all available video surveillance technologies on the market, focusing on their weaknesses and strengths. Additionally, it gives my personal suggestions of what I consider to be the preferred choice of surveillance technology in various security scenarios and circumstances.
To begin with, there are 7 video surveillance (CCTV) technologies on the market: Analogue CCTV, Advanced Analogue CCTV, IP (Network), HD-SDI (High Definition Serial Digital Interface), AHD (Analogue High Definition), HD-CVI (High Definition Composite Video Interface) and HD-TVI (High Definition Transport Video Interface).
