The Dahua IPC-PFW3849S-A180-AS-PV is a professional 180° panoramic WizSense TiOC camera designed for locations where one standard camera is not enough. Instead of using a narrow single-lens view, this model uses dual 1/2.7″ CMOS sensors to create a wide 4096 × 1860 8MP stitched image, giving excellent horizontal coverage across entrances, driveways, shopfronts, loading areas and open yards. Dahua lists the model as a 2 × 4MP TiOC Duo Splicing Fixed-focal Bullet WizSense Network Camera with 180° pixel-level splicing fusion.
This camera is especially useful when you want to reduce blind spots. Its 180° horizontal field of view allows a single camera to cover a broad scene that would normally require multiple cameras. This can simplify installation, reduce cabling, and provide a more natural overview of wide areas. The fixed 2.8mm lens provides a wide-angle view, while Dahua’s splicing technology combines the dual sensor image into one panoramic stream.
TiOC Active Deterrence
As part of Dahua’s TiOC range, this camera is not just for recording evidence after an event. It can actively respond to suspicious activity using red and blue warning lights, a built-in siren, and two-way audio. This makes it ideal for visible deterrence at homes, businesses, yards, construction sites, warehouses and after-hours commercial premises.
The camera includes a built-in dual microphone and speaker, allowing real-time audio communication through compatible Dahua software or mobile apps. Dahua specifies built-in dual microphones, a built-in speaker, and support for secure real-time talk.
Smart Dual Light
The IPC-PFW3849S-A180-AS-PV includes both IR LEDs and warm white light, giving it flexible night-time operation. It supports Smart Dual Light, allowing the camera to operate discreetly with infrared illumination and then activate visible white light when required. Dahua specifies an IR illumination distance of up to 25m and warm light distance of up to 20m.
This is useful in locations where you do not want white light running all night, but still want colour detail or deterrence when a human or vehicle is detected.
AI Human and Vehicle Detection
The camera includes Dahua WizSense intelligence with SMD 4.0 and perimeter protection. Supported intelligent functions include intrusion detection, tripwire, stay detection and loitering detection, with human and vehicle classification on supported perimeter events.
This helps reduce false alerts caused by leaves, insects, shadows or general movement. For practical security systems, human and vehicle filtering is one of the most important features because it makes push notifications and event searching much more useful.
EPTZ Target Tracking
A standout feature of this model is EPTZ, which allows the camera to electronically enlarge and track targets from intelligent alarms. Dahua describes this as the ability to enlarge and track targets of intelligent alarms.
This is particularly useful with a 180° camera because the wide panoramic view can show the whole scene, while EPTZ can help focus on the person or vehicle that triggered the event.
Excellent Outdoor Durability
The IPC-PFW3849S-A180-AS-PV is built for outdoor use, with a metal housing and IP67 weather protection. It is rated for operating temperatures from -40°C to +60°C, making it suitable for harsh Australian installation environments including exposed walls, eaves, yards and commercial premises.
Flexible Recording and Integration
The camera supports H.265, H.264, Smart H.265+ and Smart H.264+, helping reduce storage and bandwidth usage. It also supports three streams, ONVIF Profile S/G/T, CGI, microSD storage up to 512GB, NAS, FTP/SFTP, and integration with Dahua platforms including Smart PSS Lite, DSS and DMSS.
Power options include 12V DC or PoE 802.3af, making it easy to install with a compatible PoE NVR or PoE switch.

Installer Notes
This is a wide-angle panoramic camera, so placement is important. For best results, install it where the camera has a clear, open view across the area you want to monitor. Avoid placing it too close to walls, poles or signs that may dominate one side of the 180° view.
Because this model uses active deterrence, consider nearby neighbours, street-facing locations and light spill before enabling red/blue warning lights, siren or warm light activation. The deterrence functions are powerful, but they should be configured carefully to avoid nuisance activations.
For best results, pair this camera with a compatible Dahua WizSense or AI NVR. This will allow better use of SMD, smart search, event filtering and AI-based playback features. Dahua notes that Quick Pick and Smart Search work with compatible AI/smart NVRs.
The camera supports PoE 802.3af, but maximum power consumption can reach 10.3W via PoE when H.265, WDR, warm light, siren, active deterrence and intelligence are enabled, so allow adequate PoE budget on the switch or NVR.
Recommended accessories include the PFA130-E waterproof junction box and PFA157 pole mount bracket where required.

FAQs
Is the Dahua IPC-PFW3849S-A180-AS-PV an 8MP camera?
Yes. It uses two 4MP sensors to create a stitched panoramic image with a maximum resolution of 4096 × 1860, which Dahua lists as 8MP.
What does 180° splicing mean?
The camera uses two lenses/sensors and combines the images into one wide panoramic view. This allows it to cover a much wider area than a standard fixed-lens bullet camera.
Does this camera have active deterrence?
Yes. It includes red and blue warning lights, alarm sounds/siren, a built-in speaker, and two-way audio.
Does it support human and vehicle detection?
Yes. It supports Dahua WizSense features including SMD 4.0 and perimeter protection with human and vehicle classification for supported events.
Does it have a microphone?
Yes. The camera includes built-in dual microphones.
Does it have a speaker?
Yes. It includes a built-in speaker for alarm sounds and two-way audio.
Can this camera record to a microSD card?
Yes. It supports microSD cards up to 512GB.
Is it suitable for outdoor use?
Yes. It has a metal housing, IP67 weather protection, and an operating temperature range of -40°C to +60°C.
Does it support PoE?
Yes. It supports PoE 802.3af as well as 12V DC power.
What NVR should I use with this camera?
For best results, use a compatible Dahua WizSense or AI NVR so you can take advantage of smart search, SMD, event filtering and AI playback features.
Is this better than using two separate cameras?
It depends on the site. For wide areas like driveways, car parks, yards and shopfronts, this model can reduce blind spots and simplify the install. However, two separate cameras may still be better where you need different angles, longer identification distance, or coverage around corners.
Can the red and blue lights be disabled?
Yes, deterrence settings are normally configurable through the camera or compatible Dahua NVR interface. This is useful where you want AI detection and recording without visible warning lights triggering every time.
