The CCTV cameras are becoming much better quality, which is another really important development. Surveillance cams now offer up to 29 megapixels, surpassing many cameras used by professional photographers. The latest cameras can be fitted with professional SLR camera lenses to improve images taken.
A shift from the use of analogue to digital equipment is also helping drive the quality of the images the cameras capture. It helps discourage crime and has helped law enforcement officers identify offenders.
Police forces, lawyers and courts have often complained about low-res CCTV images meaning they haven’t always been accepted as evidence in legal proceedings. And if they have, poor quality images has meant that they aren’t always as decisive in helping to establish guilt or innocence as they could be.
But with better and better CCTV imagery now available through advanced hi-definition cameras (HD CCTV), the usefulness of CCTV in court is only increasing.
Manufacturers are using a range of techniques to improve image quality. For example Bosch’s top-end camera records images using the HDR (high dynamic range) dual-exposure process to capture more detail in an image’s shadows. It allows owners to save up to 30 frames per second in 1080p quality video and uses an infrared filter to improve its performance at night.
Whether it’s tracking down a thug who brutally mugged an old lady, a vandal who trashed a war memorial or searching for a missing child, CCTV plays a crucial role in tackling crime and making people safer.
The adoption of internet-connected cameras meant that more footage was being stored off-site for longer periods of time, and that gigapixel camera technology would mean even higher quality images in the future.
