The panorama channel is a 4 MP 1\/2.8\" CMOS paired with a 2.8 mm \u003cstrong\u003eF1.0 large-aperture lens\u003c\/strong\u003e, capturing a 101° wide-angle scene at all times with class-leading low-light performance (0.001 lux colour). The detail channel is a 4 MP 1\/2.8\" Sony STARVIS™ CMOS PTZ with 5 – 125 mm F1.6 – F3.6 motorised optics, 25× optical zoom and 16× digital zoom — detecting targets at 2,500 m and identifying them at 250 m. The detail head's Smart Dual Light array delivers 100 m IR plus 50 m white light. Smart Tracking links the two channels so the PTZ automatically slews onto anything the panorama's AI flags. The WizSense platform runs Auto Tracking 3.0, SMD 4.0 and Quick Pick smart search. Active deterrence stacks red\/blue light warning with 11 built-in sound alarms (plus custom uploads) and a built-in speaker. Power is PoE+ (802.3at) or 12 VDC 3 A, in a chassis rated –40 °C to +65 °C with TVS 6000 V lightning, surge and voltage-transient protection. Backed by a \u003cstrong\u003e3-year Australian warranty\u003c\/strong\u003e through CCTV Guru. Built for Australian carparks, school grounds, freight yards, depots, transport hubs and council reserves where one head should replace two cameras with brighter low-light coverage than any 8 MP panoramic in its class.\u003c\/p\u003e\n\n  \u003cdiv class=\"cg-feature-strip\"\u003e\n    \u003cdiv class=\"cg-feature-pill\"\u003e\n      \u003cdiv class=\"cg-feature-pill__icon\"\u003e\n
