The global market for Border Security Systems is projected to reach US$53.9 billion by 2025, driven by the growing focus of governments worldwide to control public safety threats, criminal and terrorists activity and entry of contraband, drugs. Another major factor also driving growth is the crackdown initiated on illegal immigration. Around the world, more number of countries are beginning to oppose and restrict migration into & out of their countries. Europe's recent surge in asylum seekers has pushed up the need for more aggressive and expanded border surveillance. The country with the largest immigrant population in the world, the United States continues to battle the flow of unauthorized immigrants into the country. The Indian government recently cracked down on illegal immigration by making amendments to the Citizenship Act of 1955 (Citizenship Amendment Act (CAA) 2019). Illegal immigration results in increased costs of healthcare and education for governments; and creates undocumented workers' cost that eat into taxpayers money. Ground based border security systems represent the major segment in the global border security systems market. Ground border security agencies confront challenges mainly from conventional international disputes, smuggling, cross border infiltrations, and illegal migration among others. Ground-based border security systems, comprising laser systems, radars, cameras, and unmanned ground vehicles among others, are widely used by military and defense agencies for surveillance, security and intelligence purposes. With growing focus onto the need to protect lawful trade and travel and dismantle cross border terrorist and criminal organizations, there is growing demand for ground-based border security systems. A wide range of systems including CCTVs, cameras, sensors, ground surveillance radar (GSR) systems, perimeter intrusion detection systems, thermal imaging IR detection camera systems, RF jammers, and biometric systems are widely used for ground based border security.

Air-based border security systems market is witnessing high growth, with unmanned aerial systems in particular experiencing high demand for border surveillance and security purposes. Aerial security systems are used for performing reconnaissance, intelligence and security operations using airborne vehicles. Air-based security systems are intended to help in border management by monitoring and reporting any security-related emergencies, detecting people and vehicles and tracking from the skies to detect less observable objects on the land, sea and in the air. Air surveillance radar (ASR) systems, unmanned aerial vehicles (UAVs) and military aircrafts and helicopters are used for maintaining aerial based security of border areas.

Sea-based platforms segment is forecast to witness high growth in the coming years. With oceans characterized by lack of clearly defined boundaries, maritime disputes are a common area of conflict among countries. Countries also are at loggerheads over uninhabited and inhabited islands. As the world's leading superpowers have long borders with seas, the number of conflicts over maritime rights remains a prime reason of disputes between countries. The South China Sea for instance is currently a point of dispute between China, Malaysia, Taiwan, Vietnam and the Philippines, with each country coming up with overlapping claims. There is also growing vulnerability of critical infrastructure such as oil refineries, atomic power plants, ports, and naval bases that are in close vicinity to maritime borders. Owing to the steady rise in maritime disputes, countries around the world are focused increasing surveillance over maritime borders, leading to rising demand for sea-based border security systems. Underwater security systems, such as submarines, advanced coastal surveillance radars, and autonomous underwater vehicles, are used for detection, identification, tracking and generation of warming for various types of underwater and surface threats.
