Modern surveillance devices are increasingly being taken off private networks and placed onto networks connected via gateway to the Internet or into Wi-Fi based local area wireless networks (LAWN). The devices are also increasingly using IPv4 and IPv6 network stacks and some form of embedded processing or compute built in. Additionally, some specialist devices are using assistive technologies such as GPS or A-GPS. This paper explored the issues with use of the technologies in a networked environment, both wireless and internetworked. Analysis of these systems shows that the use of IP based CCTV systems carries greater risk than traditional CCTV systems, primarily due to the exposure to IP based vulnerabilities. Furthermore, Wi-Fi based IP CCTV systems are additionally susceptible to remote, physical denial of service attacks due to the broadcast nature of wireless communication systems. Interception of traffic is possible with IP based systems, and again, Wi-Fi IP based CCTV systems are more susceptible due to protocol vulnerabilities and lack of processing power. The paper concludes that more research is needed in this area to identify and classify generic vulnerabilities that these systems are vulnerable to, and to present a framework which can be used to mitigate the risk of adopting these systems.
