With the onset of dark winter nights, Derwent is urging the security industry to give greater consideration to illumination.

The company claims that many CCTV cameras fail to capture useable images at night due to insufficient or non-existent illumination.

The company is launching its Dark Nights campaign to "hammer home to the industry the importance of specifying and installing the correct type of lighting". Derwent believes infrared is the best illumination available for CCTV. To tie in with the launch of the Dark Nights campaign, Derwent is releasing an update to its 'Night-time Handbook', with information relevant to anyone involved in installing or specifying CCTV systems.
