§ 01Overview
What the DH-IPC-HFW3466T-AS-P is
The Dahua DH-IPC-HFW3466T-AS-P is a 4MP WizSense wide-angle bullet that covers a broad scene from a single camera.
It uses one fixed 2.1mm lens to deliver a 180-degree horizontal field of view, not a multi-lens stitched panorama, with lens distortion correction to keep the wide image usable.
EPTZ lets you zoom into and track targets within that wide frame, giving an overview and detail from the same camera.
A 1/2.7-inch 4MP sensor with Starlight low light and 120dB WDR holds detail in dim and backlit scenes, and SMD 3.0 with perimeter protection classifies movement as human or vehicle to keep alerts focused.
A built-in microphone records on-site audio.
Note that Smart IR reaches up to 20m, so this camera is best for shorter-range wide coverage such as a driveway, frontage or yard rather than long-distance identification, and because the view is spread across 180 degrees the detail at the edges is lower than a standard-angle camera.
It records monochrome at night, has a microphone but no speaker, and runs on 12V DC or PoE.

§ 04Why choose this
Built for the way you actually use the DH-IPC-HFW3466T-AS-P
Overview and detail together
EPTZ zooms into and tracks targets within the wide image, so you get situational awareness and a closer look from one camera.
Filtered alerts
SMD 3.0 and perimeter protection classify humans and vehicles, cutting nuisance alerts from animals, foliage and weather.
Simple single channel
Unlike a multi-sensor panoramic, it registers as one channel and sets up like a normal camera, while still covering a wide scene.
§ 05Where it fits
Right at home in these scenarios
Shop frontages and entries
A 180-degree view covers an entire frontage, doorway and footpath from one camera, with classification to focus alerts.
Driveways and courtyards
Removes blind spots across a wide driveway or courtyard, with EPTZ to look closer at activity within the scene.
Car parks and yards
Wide situational coverage of open areas where a single standard-angle camera would leave gaps at the edges.
Corners and wall junctions
Mounted on a wall, the wide lens captures both directions along a frontage or boundary from a single point.
§ 06Setup
Installation & setup
Mount for wide coverage
Fix the bullet to a wall, eave or corner where the 180-degree lens can take in the whole area. Keep the area of interest within roughly 10 to 15m for the clearest detail.
Power over PoE or 12V DC
Run a single PoE network cable from a switch or NVR, or provide a 12V DC supply where PoE is not available.
Tidy the cabling
For surface cabling or extra clearance, add a Dahua junction box such as the PFA137; confirm it suits this bullet before ordering.
Set EPTZ and smart rules
Configure EPTZ views to zoom into key areas, and set tripwire and intrusion rules with human and vehicle classification across the wide frame.
