Abstract
Various methods have been used to combat theft and loss of property in the past.
Closed-Circuit Television (CCTV) surveillance is among the methods civilians use to protect
their property. In recent times wired systems have been found with wires that have
been cut, affecting the feedback loop to which responses from the camera are monitored.
This problem is an increasing safety concern for companies and individuals that rely on
camera monitoring systems for security and protection. The system’s operation is then
compromised, and criminal offenders can get away with illegal activities that constitute
mass consequences.
The document aims to prove how the general reliability of surveillance systems can be
improved with the aid of wireless sensor networks (WSNs). WSNs are autonomous devices
with sensing, processing, and communicating capabilities for several functions, including
monitoring the real world, security surveillance and medical purposes. Further, a wired
network prototype monitored by a wireless network is designed and implemented.
A simulation study implemented for a residential scenario showed a test for randomly
placed nodes for throughput, path loss ratio, and latency for a WLAN using the 802.11n
protocol. The network’s performance was tested with a CCTV camera unit to enhance the
safety of the surveillance system. The time specifications were not reached since changes
were made to the initial specified design to limit false alarms. This can be improved if
path loss models can be simulated for different wireless topologies, and the one with better
propagation must be selected.
