The footage shows the terror suspect in a coach station in Birmingham mingling with commuters.
Omar fled the capital the day after he made a failed attempt to detonate a rucksack bomb on a Tube train near London's Warren Street station, Woolwich Crown Court was told.
The head-to-toe outfit gave others at Digbeth coach station no clue that the man inside was wanted by anti-terror police.
The court has already heard how Omar was captured on CCTV wearing the burka at Golders Green coach station in north London earlier in the day.
He was eventually arrested at a house in Birmingham on Wednesday, July 27.
The jury was told yesterday how firearms officers nearly gunned Omar down when they found him in the house standing in a bath wearing what they feared was a rucksack filled with explosives.
Specialist police officers told Woolwich Crown Court how stun grenades were thrown into every room before a violent struggle ensued with the defendant.
One officer said he punched Omar - who was fully clothed - as hard as he could in the face while another repeatedly stunned him with a Taser gun.
At one point another officer had the safety catch off his sub-machine gun and was aiming his weapon at the back of Omar's head.
Omar is one of six men accused of hatching an extremist Muslim plot to detonate shrapnel-packed rucksack bombs on the London transport system exactly two weeks after the July 7 terror attacks.
His co-defendants are Muktar Said Ibrahim, 29, of Stoke Newington, north London, Adel Yahya, 29, of High Road, Tottenham, north London, Manfo Kwaku Asiedu, 33, of no fixed address, Hussain Osman, 28, of no fixed address and Ramzi Mohammed, 25, of North Kensington, west London.
