The armed forces have stepped up vigilance and patrolling along the Kashmir border to restrict infiltration bids by militants.
The Border Security Force (BSF) is installing high-resolution cameras and monitoring the border to stop infiltrators from entering the Indian territory during the winter.
BSF deputy inspector general (DIG) Virender Singh said the cameras were helping the forces maintain a vigilant eye along the border.
"In winters, when heavy fog envelops the area, normal surveillance cameras do not function properly, which is why we have installed high-resolution closed-circuit television (CCTV) cameras. These cameras have high power and can give us a clear view even in thick fog," he said.
Tension has been prevailing between the two nations after regular violations of the November 2003 ceasefire agreement.
Although artillery fire frequently rattles the Line of Control (LoC), infiltration and cross-border ambushes have become rare.
Singh said the border was intact and forces were alert to foil infiltration bids.
"A few days ago, there were reports in the media that four infiltrators had crossed the border. However, I want to confirm that no such infiltration took place. The border is intact and our forces are alert.
There is no breach. All our obstacle systems are fully functional, without any interference," he added.
In October, around 30 to 40 heavily-armed fighters had crossed the LoC in the Keran sector and holed up for nearly nine days in the thick forests skirting the area.
