Dahua DH-IPC-HFW3849TP-ZAS-IL-27135 - 8MP 4K Smart Dual Light WizSense AI Vari-focal Bullet IP CCTV Camera

Dahua DH-IPC-HFW3849TP-ZAS-IL-27135

The DH-IPC-HFW3849TP-ZAS-IL-27135 is an 8MP (3840 x 2160) bullet camera with a motorised 2.7-13.5 mm lens. You can zoom and focus it remotely after it is fixed in place, so the same camera can cover a wide driveway at 114 degrees or narrow to 32 degrees to watch a gate or doorway at distance.

Smart Dual Light is the practical feature here. At night it records in IR, and when a person or vehicle enters the scene its warm light switches on so the event is captured in colour. Both lights reach up to 60 m. WizSense perimeter protection classifies humans and vehicles, and SMD 4.0 filters out motion from leaves and animals.

It has a built-in microphone, electronic image stabilisation for poles that move in the wind, and a Micro SD slot up to 512 GB. The housing is IP67 (IK10 optional) and it runs from 12 VDC or standard PoE (802.3af, 12.5 W max).

Also listed as IPC-HFW3849TP-ZAS-IL-27135.

Key features

• 8MP 4K output: 3840 x 2160 at up to 25/30 fps from a 1/2.7-inch CMOS sensor.
• Motorised vari-focal 2.7-13.5mm lens, F1.4, with a 114° to 32° horizontal field of view.
• Smart Dual Light: built-in multi-core IR and warm light, each up to 60m, with three illumination modes listed by Dahua.
• WizSense AI: tripwire and intrusion with human and vehicle classification, SMD 4.0, AcuPick smart search and AI scene self-adaptation.
• Electronic image stabilisation (EIS), face detection (full image), stay detection and loitering detection.
• Super AI Coding (H.265 and H.264) to reduce storage and transmission costs.
• Built-in microphone for real-time audio.
• IP67 housing with optional IK10, 12 VDC or PoE (802.3af) power.
• Micro SD card slot up to 512GB, ONVIF Profile S, G, T and M.

Technical specification

DORI distances

DORI (Detect, Observe, Recognise, Identify) distances to EN 62676-4, from Dahua's datasheet. They do not reflect intelligent function distances.

Works with

Optional accessories from Dahua's datasheet that Zenith lists:

• DH-PFA130-E waterproof junction box
• DH-PFA135 junction box
• DH-PFA151 corner mount bracket
• DH-PFA152-E pole mount bracket
• DH-PFM900-E-V2 integrated mount tester
• Dahua DHI-NVR5208-8P-EI2 8 Channel PoE NVR: 8 PoE channels and support for IP cameras up to 32MP, so the 8MP stream is within range.

These are general compatibility suggestions (same brand, ONVIF IP, matching power and channel specifications), not pairings we have tested.

Common questions

How does Smart Dual Light work on this camera?

Dahua's datasheet says the IR illuminator is usually on at night. When a target appears in the monitored area the light comes on and the camera records full-colour video, then it returns to IR when the target leaves. Dahua lists three illumination modes. See our Smart Dual Light guide.

Can the zoom be adjusted after installation?

Yes. The 2.7-13.5mm lens is a motorised vari-focal lens, so zoom and focus are adjustable without changing the lens.

How far do the IR and warm light reach?

Up to 60m each, according to Dahua's datasheet.

Is it vandal resistant?

The datasheet lists IP67 protection and IK10 as optional. Check the IK10 option when ordering if impact protection matters.

Does it have a speaker or siren?

Dahua's datasheet lists a built-in microphone for this model and does not list a speaker or a sound and light alarm. For those features see the TiOC PRO version.

What is WizSense?

Dahua describes WizSense as a series of AI products that use an independent AI chip and deep learning, focused on human and vehicle detection. See our WizSense guide.

How is it powered?

From 12 VDC (±30%) or PoE (802.3af). Dahua advises disconnecting one source if the adapter and PoE are connected at the same time. Basic power use is 3.8 W on 12 VDC and 5.3 W on PoE.

Can it be used as an outdoor camera?

Yes. Dahua lists IP67 protection (IK10 optional) and an operating temperature of -30°C to +60°C, and it runs from 12 VDC or PoE (802.3af).

Is it a waterproof camera?

The housing is rated IP67 in Dahua's datasheet, with IK10 listed as optional.

Is it an infrared camera?

Yes. Dahua lists a built-in IR illuminator up to 60m, plus warm light up to 60m for full-colour video, and 0 lux minimum illumination with the illuminator on.

Does it work with a Hikvision NVR?

It supports ONVIF Profile S, G, T and M, so it can generally be added to an ONVIF-compatible recorder. Dahua-specific AI search features may not be available on a third-party recorder.
