HD/megapixel technology enables network cameras to provide higher resolution of video images than analogue CCTV, i.e. the ability to see more details or have a wider coverage. An HDTV or megapixel network camera, the resolution is at least three times better than an analogue CCTV camera.
“Quote from The HDCCTV Alliance has predicted that the number of HD cameras will rise to over 3.7 million by 2016.”
A shift from the use of analogue to digital equipment is also helping drive the quality of the images the cameras capture.
Defenders of the technology note that it helps discourage crime and has helped law enforcement officers identify offenders.
An earlier report by the Integrated CCTV news site said that evidence gathered by surveillance cameras had helped secure some of the convictions that followed 2011’s London riots.”
