What trends can we expect in 2013? City surveillance, HDcctv, cloud-based video, the Indian and Chinese markets, analytics, the move to 3D and thermal imaging... All are covered in IMS Research's forecasts for 2013, as Brian Sims reports. Wireless infrastructure has a number of things going for it right now. First, it reduces the cost of infrastructure when compared with the traditional trenching and laying of cable which, in the current economic environment, is unsurprisingly popular. Second, wireless infrastructure offers networking in areas of cultural significance, such as city centres and historic sites, without the need to dig up roads: in some cases, it's the only option. Third, wireless technology can be used in temporary video surveillance installations to provide a degree of flexibility that a wired solution just cannot offer. In these days of austerity, moving cameras when and where you need them is a more attractive option than buying new ones. Finally, the end user sector that suits wireless infrastructure best is city surveillance (municipalities), which just happens to be the fastest-growing vertical market for video surveillance.
