Nova Scotia highway webcams are operated by the Nova Scotia Department of Transportation and Infrastructure Renewal (TIR). Most are mounted on tall steel towers, most of which have weather sensors included on the tower. The sensors measure temperature, humidity, barometric pressure and wind direction and speed.
The webcam pic below is more or less real time and will update every 30 to 40 minutes, depending on conditions.
This highway camera is right at the top of Kelly's Mountain on a straight stretch of Highway 1, the Trans Canada Highway. This is northwest of the Seal Islands Bridge and New Harris. The camera looks southeast down the highway in the direction of the bridge. Camera and tower are enclosed by a chain link fence and operated by a pair of large solar panels within the fence. This is 30 kilometres by road out of North Sydney, which is pretty much straight east of the camera.
