The BSF attributes this rise to improved anti-drone strategies and advanced technical measures. 

• Previously, Pakistani syndicates were using land routes but now they are using Chinese-made drones to smuggle drugs, arms, and ammunition to destabilize India
  • This is because traditional security measures such as surveillance cameras may not be capable of detecting drones at a distance. 

Other security threats posed by drones

• Weaponization of drones: Modification of small commercial drones allows for easy carrying of explosives or weaponry.
• Disruption of Critical Infrastructure: Drones can carry out cyber-attacks, electronic jamming or physical attacks to disrupt infrastructure networks.
• Privacy concerns: Drones loaded with high-definition cameras can threaten privacy of common citizens.
• Drone Swarms: This refers to a situation where large number of drones operate autonomously in coordinated formations, potentially overwhelming defence systems.

Anti-drone technologies 

• Radio Frequency sensors that can detect known drone radio signals over wide areas
• High-Power Microwave (HPM) systems emit stream of microwave energy in a wide area and are best suited for area denial operations against personnel or small electronics. 
• Integrated drone detection and interdiction systems (IDD&IS) deployed along the northern borders with China provide both “soft kills” through jamming and “hard kills” using lasers.
