In the analog/HD CCTV world, edge based hacking attacks on the network are impossible since the hacker needs to gain direct access to the DVR. IP networked cameras, on the other hand, are highly vulnerable to edge based hacking since WiFi systems can be overcome using jammers and are also liable to denial of service (DoS) attacks by UDP packet flooding. Does this then merit the proven viability of using HD cameras over co-axial cables for security and surveillance applications?

Market research group IMS Research give HDcctv a 1% share of CCTV camera sales in 2011. In 2009, 42 million CCTV cameras were shipped.
