Video surveillance is one the most widely used technologies in the industry, and was expected to generate nearly 16 billion U.S. dollars in revenue worldwide in 2016. Both IP-based and non-IP based are technologies commonly used for video surveillance, although non-IP generates, on average, more the greater share of industry revenue. North America and China are the two main regional markets for video surveillance technology. While China is forecast to have almost a quarter of the market share by 2019, the United States has the greatest number of surveillance cameras per capita. Video surveillance is the second most profitable security product in the U.S., second to integrated non-residential systems. Access control and intrusion alarms also represent a significant share of the U.S. market.
Access control and alarm systems are not only popular in the U.S., but also worldwide. In 2018, the global identity and access management market is expected to reach about seven billion U.S. dollars in revenues. In terms of companies, Assa Abloy, Allegion and Aiphone are some of the leading providers of access control equipment and solutions worldwide in 2014.
Besides the more “traditional” fields of use, such as video, alarm and access control, security technology is evolving in conjunction with the new technology trends such as the Internet of Things (IoT). The Internet of Things, a tech phenomenon that has been gaining momentum, is expected to have an impact on the security surveillance market. Connected home (IoT) security device shipments are forecast to grow from 41 million units shipped in 2014 to 709 million units in 2019. Also, the market for IT security products and software continues to grow as concerns about IT security related matters such as data security and online privacy arise. The expenditure on IT security products worldwide is forecast to reach to 43 billion U.S. dollars by 2018.
