In this paper we describe a prototype surveillance system that leverages smart sensor motes, intelligent video, and
Sensor Web technologies to aid in large area monitoring operations and to enhance the security of borders and
critical infrastructures. Intelligent video has emerged as a promising tool amid growing concern about border
security and vulnerable entry points. However, numerous barriers exist that limit the effectiveness of surveillance
video in large area protection; such as the number of cameras needed to provide coverage, large volumes of data to
be processed and disseminated, lack of smart sensors to detect potential threats and limited bandwidth to capture and
distribute video data. We present a concept prototype that addresses these obstacles by employing a Smart Video
Node in a Sensor Web framework. Smart Video Node (SVN) is an IP video camera with automated event detection
capability. SVNs are cued by inexpensive sensor motes to detect the existence of humans or vehicles. Based on
sensor motes' observations cameras are slewed in to observe the activity and automated video analysis detects
potential threats to be disseminated as "alerts". Sensor Web framework enables quick and efficient identification of
available sensors, collects data from disparate sensors, automatically tasks various sensors based on observations or
events received from other sensors, and receives and disseminates alerts from multiple sensors. The prototype
system is implemented by leveraging intuVision's intelligent video, Northrop Grumman's sensor motes and
SensorWeb technologies. Implementation of a deployable system with Smart Video Nodes and sensor motes within
the SensorWeb platform is currently underway. The final product will have many applications in commercial,
government and military systems.
