The livestream you shared is from a SkylineWebcams camera in Downtown Singapore. Based on the description and the linked Google Street View reference in the video description, the camera is positioned near the Capitol complex area at City Hall.
Most likely camera location
The camera is installed on or near the Capitol Singapore / Capitol Kempinski Hotel complex, around Stamford Road / City Hall.
Why this location matches the livestream
Clues from the stream description and view:
The stream description lists “Capitol” as a visible landmark.
The viewing angle matches a north-east facing skyline view over Marina Bay and the CBD from City Hall.
From that vantage point you typically see:
Marina Bay Sands
Gardens by the Bay
Singapore Flyer
parts of the CBD skyline.
These landmarks align with what SkylineWebcams says the feed shows: a downtown Singapore skyline panorama.
Practical interpretation
So the camera is likely mounted:
Rooftop or upper floor of the Capitol complex
Rough coordinates: City Hall / Stamford Road area
Facing Marina Bay / CBD

If you want, send me a screenshot from the livestream and I can pinpoint the exact building or even the rooftop position (I can usually triangulate it within ~1–2 buildings).
