The 27-second clip shows a grey Skoda car drive up to the farmhouse gate out of which two men emerge, one brandishing a revolver, apparently to threaten the security guard, and open the gate.
The gun-toting man turns briefly and his face is visible for a few seconds before the two follow the car out of the farmhouse as the camera clock reads 9:14 in the morning.
Bhardwaj, 62, who had also contested polls earlier, was shot dead inside his farmhouse on Tuesday morning by the two assailants in south Delhi who then fled the scene.
The slain businessman and politician was one of the richest contestants of elections in 2009 on a BSP party ticket, reports said. He, however, did not win the polls.
Initial reports said the killers drove in a black Skoda or BMW and entered the farmhouse at Rajokri and then fled after shooting him. He was taken to Fortis Hospital where he was declared dead.
The motive behind the killing is yet to be known.
According to information available on Bhardwaj, he was one of the richest contestants of the 2009 Lok Sabha polls and had declared assets worth over Rs 600 crore.
Bhardwaj, who had contested from the West Delhi constituency unsuccessfully, had real estate business, hotels and was in the education sector too.
His relatives were tight lipped so far on what could be the cause of enmity that took his life. One of the woman relatives was seen crying inside a car.
