Enhancing 'natural' surveillance in public space is a core aspect of Crime Prevention Through Environmental Design strategies. Surveillance is also a crucial issue for working activities in many complex buildings, such as the provision of patient care in hospitals.

Intelligent Space has developed a computer model which calculates objective values for surveillance within buildings and street environments.

Crime Prevention

Surveillance modelling is used in crime prevention to quantify the protection of 'eyes on the street' from both the local community (natural surveillance) and from CCTV (artificial surveillance).

• Areas of public space that needed improved surveillance were targeted using Intelligent Space analysis for the masterplan to redevelop the Sidgwick site on behalf of Cambridge University.
• Intelligent Space provided the Home Office with evidence on the role of casual surveillance in reducing criminal incidence in schools to inform guidance on safer school design.

Care Provision

In the design of complex buildings such as hospitals, schools and prisons, modelling can be used to ensure that adequate levels of surveillance are present where required, such as the supervision of patients from staff bases. It can also be used to prevent surveillance where it is detrimental, for example in issues of patient privacy and dignity.

• Surveillance modelling was used to advise NHS Estates on how to improve the delivery of intensive care by creating environments where highly vulnerable patients are better overlooked.
