This paper describes how we deploy video surveillance techniques to monitor the activities within a sensor network in order to detect environmental events. This approach combines video and sensor networks in a completely different
way to what would be considered the norm. Sensor networks
consist of a collection of autonomous, self-powered
nodes which sample their environment to detect anything
from chemical pollutants to atypical sound patterns which
they report through an ad hoc network. In order to reduce
power consumption nodes have the capacity to communicate
with neighbouring nodes only. Typically these communications
are via radio waves but in this paper the sensor nodes communicate to a base station through patterns emitted
by LEDs and captured by a video camera. The LEDs are chemically coated to react to their environment and on doing so emit light which is then picked up by video analysis.
There are several advantages to this approach and to demonstrate we have constructed a controlled test environment.
In this paper we introduce and briefly describe this
environment and the sensor nodes but focus mainly on the
video capture, image processing and data visualisation techniques
used to indicate these events to a user monitoring the
