Dahua DH-IPC-EBW81242P-AS-S2 12MP IR Fisheye WizMind Network Camera
The Dahua IPC-EBW81242-AS-S2 is a 12 MP WizMind fisheye that gives a single overhead 360-degree view of a room or open floor. One ceiling-mounted camera covers a whole area with no blind spots, and on-board WizMind analytics turn that view into heat maps and people-counting data for business as well as security.

§ 01Overview
What the IPC-EBW81242-AS-S2 is
The Dahua IPC-EBW81242-AS-S2 is a 12 MP WizMind fisheye built to watch a whole space from a single point.
Mounted in the centre of a ceiling, its 1.85 mm panoramic lens captures a 360-degree view of the floor below in 4000 x 3000 detail, so one camera replaces several fixed cameras and removes the blind spots between them.
Built-in dewarping presents the circular image as usable panoramic and quad views on screen.
What sets it apart is what it does with that view.
WizMind deep-learning analytics generate heat maps that show where people spend time, count people entering and leaving, and measure queues and dwell time, which makes it as useful to a retail or venue manager as to security.
It also runs IVS rules such as tripwire and intrusion with human-focused refinement to cut nuisance alarms.
Worth being clear here: this is a business-analytics and overview camera, not a human-and-vehicle perimeter camera, so it is not the tool for classifying vehicles along a boundary.
A couple of honest points on the spec.
Audio is by a built-in dual microphone with line in and line out connectors, so to talk back you add an external active speaker; it does not include a built-in speaker, so it is not a two-way-audio camera on its own.
Infrared reaches about 10 metres, which suits a typical room ceiling for low-light cover rather than long-range night security, so it is at its best indoors or under a sheltered canopy.
The IP67 and IK10 metal body does allow sheltered outdoor mounting.
Power is PoE+ or 12 VDC, and H.265 keeps the large 12 MP stream efficient.

§ 04Why choose this
Built for the way you actually use the IPC-EBW81242-AS-S2
Insight, not just video
WizMind heat maps, people counting and queue analytics turn the overhead view into data that helps run a shop, venue or office.
High resolution across the scene
A 12 MP 1/1.7" sensor keeps usable detail across the wide panorama, with dewarping into flat panoramic and quad views.
Tough and efficient
An IP67 and IK10 metal body suits sheltered indoor and outdoor positions, and H.265 keeps the large stream in check.
§ 05Where it fits
Right at home in these scenarios
Retail floors
Overhead coverage of a shop with heat maps and people counting to understand customer flow and staffing.
Banking and reception halls
A single discreet fisheye watches the whole space and times queues at counters and desks.
Open-plan offices and warehouses
Wide overview of an open area with people-movement analytics and no blind spots.
Transport concourses
Crowd overview and counting across a hall, with dewarped views for operators.
§ 06Setup
Installation & setup
In the box
WizMind fisheye camera, mounting plate and the printed guide. A flush, pendant or wall-mount kit is selected to suit the ceiling and bought separately.
Power and cabling
Run a single network cable for PoE+ (802.3at), or use 12 VDC. A gigabit path keeps the 12 MP stream from being throttled.
Mounting
Fit it in the centre of the ceiling over the area you want covered, as high and central as practical, so the 360-degree view is even and the dewarped images stay balanced.
Setup
Choose the on-screen dewarp mode (panoramic or quad), set the people-counting, heat-map and IVS rules, and tune the infrared and image settings for the room.
