Once seen as an example of government ’ s determination to play ‘ Big Brother ’ in people ’ s lives , security
systems are now accepted as being
a crucial part of crime prevention , from your local troublemaker stealing from the village shop , to large scale terrorist attacks . Unfortunately , we are now living in an age when barely a week goes by without another mass atrocity being reported somewhere in the world . However , almost immediately after these horrific events media channels are full of CCTV images of the suspects . While our security services cannot always prevent the crime , the improvement in technology is making it easier to catch the perpetrators , and the advancements mean the grainy footage is quickly becoming a thing of the past .
Hanwha Techwin has broadened its Samsung Wisenet P series with the introduction of a 7.3 megapixel 180 ° panoramic camera . Designed for monitoring large open areas with just one camera , the PNM-9020V is equipped with multi-sensors which enable it to capture superb quality seamlessly stitched 180 ° images . Four 2MP images with 3.6mm lenses work in harmony to produce the 180 ° composite images . This is achieved with the help of a synchronised alignment lever located in the centre of the camera which raises and lowers the sensors in unison to facilitate easy set up .
Tim Biddulph , head of product management for Hanwha Techwin Europe , explains , ‘ The PNM-9020V ’ s high definition and panoramic capabilities means end users can achieve an exceptionally high return on investment ( ROI ), as it can
