In the video, a man can be seen tampering with the electric gate — which he quickly manages to open.
Another man then enters the garden and attempts to disable a CCTV camera in the corner of the property.
He is followed by two men, one of whom covers his face with a gloved hand.
One of the men then moves the camera from its position.
Watch the video here:
The male resident (41) was home alone when the robbers entered his house at about 10am.
The resident had gone to investigate a noise he heard in the dining room, when he saw three men, one of whom was armed with a gun.
When the resident shouted at the intruders, the armed man pointed the weapon at him.
The resident fled to a room, where he locked and barricaded the door with furniture.
The robbers fled the house with a television set. They were travelling in a silver BMW.
