Hikvision DS-2DP8A440IXG1-LEF/416(F0) — 16 MP Panoramic and PTZ Camera
Every PTZ makes the same uncomfortable trade. While it is zoomed in on one thing it is, by definition, not watching anything else, and the moment an operator or an auto-track decides to follow a figure across the yard, the rest of the yard goes unrecorded. Reviewing that footage afterwards is an exercise in guessing what you missed.
This camera stops making the trade. A 16 megapixel panoramic channel covers 180 degrees horizontally and 110 vertically, fixed, continuous, recording all of it at 5520 × 2400 whatever else is happening. Alongside it, a separate 40x PTZ head runs from 6 to 240 mm and closes to 1.8 degrees. The panorama never blinks; the PTZ goes and looks.
The tracking is built around that arrangement rather than bolted onto it: panorama tracking uses the wide channel to spot movement and hands the target to the zoom head, and patrol tracking passes attention between multiple detection zones. Infrared reaches 300 m. There is a fibre port on the back, 135 watts going in, and 14.6 kg of camera on the bracket. Nobody clips this to a soffit.

Why there is no coverage diagram on this page
Fixed cameras in this catalogue carry an interactive diagram of exactly what they cover. This one is half fixed and half moving, and Hikvision publishes no DORI distances for either channel — so rather than invent figures that would not be comparable with the manufacturer numbers used elsewhere here, we have left the diagram out.
What can be said without inventing anything: the panoramic channel is genuinely fixed at 180 degrees by 110, so its coverage is a known quantity once the mounting height and tilt are set. The PTZ head has no fixed coverage at all, by design. And the infrared reaches 300 metres, which on an unlit site is the real limit on both regardless of what the optics could resolve in daylight.
If you need certainty about a specific area rather than reach across a large one, a fixed camera is the better instrument, and its page will show you precisely what it sees.

Works with SmartGard.AI
A camera that watches 180 degrees continuously and automatically zooms in on whatever moved is, on a large site, a machine for generating alerts. Every vehicle, every contractor, every fox. Panorama tracking will dutifully hand each one to the zoom head, and by the second week nobody is reading the notifications.
The system needs one thing from a camera: the ability to report that something happened. This one reports line crossing, region entry and exit, unattended baggage, multi-target detection on the PTZ channel, people density and congestion on the panoramic one. SmartGard.AI reads the frame each trigger arrives with, judges it against zone rules written in your own words, and passes on only what earns it. On a site big enough to justify this camera, that filtering is not a nicety — it is the difference between a system people use and one they mute.
Worth knowing if you write zone rules for a moving camera: rules drawn against the fixed panoramic channel stay valid, because it does not move. Rules drawn against a PTZ preset are only meaningful at that preset.
