1. A surveillance camera arrangement comprising: A PTZ camera configured to: perform panning movements about a pan axis; and perform tilting movements within a plane of tilting motion, such that a range of possible tilt positions is captured by the plane of tilting motion, the plane of tilting motion being offset from, and substantially parallel to and non-coincident with, the pan axis, and a large domain sensor substantially aligned with the pan axis, the large domain sensor having a wider field of view than the PTZ camera, wherein the PTZ camera is mechanically coupled to the large domain sensor.
