Over the years, the electronic surveillance along the LoC to check infiltration has been significantly improved. However, the existing Anti-Infiltration Obstacle System (AIOS) which was installed between 2003 to 2005 has highly degraded due to snow. Consequently, a proposal was made by the army for installation of smart fence along the entire stretch which is over 700 km with various sensors integrated into it. But due to its high installation cost, a hybrid model is being adopted. The fence will be integrated with Light Detection and Ranging (LIDAR) sensors, cameras and infrared sensors among others. The topic is related to Defence and Internal security of India.
