Abstract

Closed circuit television (CCTV) is used extensively to improve public safety and protect critical infrastructure in many countries. However, researchers have obtained mixed findings regarding its effectiveness. One possible explanation for this is that insufficient attention has been devoted to the human side of CCTV systems and detection processes, namely CCTV surveillance operators. These operators are required to sustain high levels of alertness and attention over extended periods of time, as with CCTV surveillance. Vigilance research has identified numerous factors that influence performance. However, these have typically been developed in isolation from the perceptual-cognitive processes involved in visual search and monitoring - key activities of operators. The aim of this paper was to integrate the factors into a holistic theoretical model of performance for CCTV operators, drawing on areas such as vigilance, human factors in system design, and perceptual-cognitive processes involved in visual search and monitoring. The model consists of five key components - the socio-political and industry contexts, organisational context, technological system and job design, operator processes and performance. It can be used as a basis for research regarding CCTV and for diagnosing performance issues in the operational context.
闭路电视监控操作员性能模型
闭路电视(CCTV)在许多国家被广泛用于改善公共安全和保护关键基础设施。然而,关于它的有效性,研究人员得到了不同的发现。一种可能的解释是,人们对闭路电视系统和检测过程中的人的方面,即闭路电视监控操作员的关注不够。这些操作员需要在长时间内保持高度的警觉性和注意力,就像闭路电视监控一样。警惕性研究已经确定了许多影响表现的因素。然而,这些通常是在与操作员的视觉搜索和监控关键活动所涉及的感知认知过程隔离的情况下开发的。本文的目的是利用警惕性、系统设计中的人为因素以及视觉搜索和监控中涉及的感知-认知过程等领域,将这些因素整合到CCTV操作员的整体绩效理论模型中。该模型由五个关键部分组成:社会政治和行业环境、组织环境、技术系统和工作设计、操作员流程和绩效。它可以作为研究CCTV和诊断操作环境中的性能问题的基础。
