The BSF has recently procured Israeli tethered drones and thermal imagers to check smuggling and illegal infiltration in Dhubri sector, where a major part of the India-Bangladesh border passes through a riverine stretch, making it difficult to erect fences.
The drones, equipped with day-night vision cameras, can fly up to a height of 150 metre to capture images on the ground, especially of isolated areas not visible to unaided human eye, Piyush Mordia, the Inspector General (IG) of BSF’s Guwahati Frontier, said.
“They (drones) are like kites capturing aerial view images. The cable attached to the drone is remotely controlled from the ground to adjust its height and directions,” Mordia told PTI on Tuesday.
The 61-km-long border in Dhubri area, where the Brahmaputra enters Bangladesh, comprises vast chars (sand bars) and multiple river channels that make border patrolling a daunting task, especially during the monsoons.
“Cattle smuggling and drug trafficking activities are usually carried out at night. These newly employed drones will be able to send images of smugglers hiding in the vicinity of the border area during day time,” the BSF IG explained.
Given the topography of Dhubri district, miscreants often take the underwater route to sneak into the country illegally, Mordia stated.
“The BSF has also engaged underwater thermal imagers – which are non-contact temperature measurement sensor devices – to detect movement of people, animals and smuggled goods.
“The tethered drones and imagers will work as deterrents for cross-border smugglers once they found out they were under surveillance,” he maintained.
Declining to divulge the exact number of drones engaged in the sector, Mordia said the aerial device would restrict its movement and images to the Indian Territory. – PTI
