Description
Security is a contentious issue in society and the globe as a whole. It is hard
to exaggerate the importance of safety in a world plagued by vandalism and
crime, yet it is critical. While the use of video surveillance equipment has
increased significantly in recent years, the cost of video surveillance
equipment has increased relative to places of low income across Africa. This
research work aims to develop a lower-cost, a real-time security monitoring
system that combines the ESP32 with an OV2640 (OV) camera to detect
motion via a pyroelectric infrared (PIR) sensor and the Internet of Things in
order to monitor activity and alert the user via SMS text in the event of an
intruder and subsequently transmit the video captured through the use of the
TWILIO application programming interface (API). On deploying and testing the
system, the result indicates that as long as the visual representation of data
on the Ismart platform corresponds to the actual video taken in real-time in the
overage area and the motion sensor unit functions properly, resulting in a
lower-cost operational surveillance system. The time required to send data is
dependent on the volume of traffic on the network and the speed of the
internet connection. It is concluded that the proposed system is less
expensive than alternatives while still retaining its efficiency.
