Dahua DH-IPC-HFW3849T1-ZAS-PV-ANZ-S2 8MP 4K TiOC 3.0 AcuPick Active Deterrence Bullet Camera | 2.7–13.5mm Motorized Vari-Focal

The Dahua DH-IPC-HFW3849T1-ZAS-PV-ANZ-S2 is an advanced 8MP 4K TiOC 3.0 active deterrence bullet camera designed for high-detail surveillance across residential, commercial and industrial environments. Featuring a 1/2.8" CMOS sensor, F1.0 aperture and a 2.7–13.5mm motorized vari-focal lens, it provides flexible viewing from a wide-angle overview through to detailed long-range monitoring.

With Smart Dual Light technology, the camera combines IR and warm-light illumination with up to 50m IR range and 40m warm-light range, helping deliver clear color or black-and-white images in low-light conditions. The integrated red and blue warning lights, siren and two-way audio provide an effective active deterrence solution when suspicious activity is detected.

Advanced AI features including AcuPick, SMD 4.0, human and vehicle classification, intrusion detection and tripwire help reduce false alarms and make it easier to locate and investigate events. 120dB WDR, 3D noise reduction, BLC, HLC, EIS and AI Coding further enhance image quality and recording efficiency.

The camera supports PoE (802.3af) for simplified installation, up to 512GB Micro SD storage, ONVIF compatibility and IP67 weather protection, making it suitable for exposed outdoor installations such as driveways, car parks, commercial premises, warehouses, farms and large property perimeters.

Product Specifications

Lens & DORI Performance

The motorized 2.7–13.5mm vari-focal lens allows the camera to be adjusted between wide-area coverage and long-distance monitoring.

DORI distances are based on the EN 62676-4 standard and indicate the approximate ability to detect, observe, recognize and identify objects. Intelligent detection distances may vary depending on the installation environment.

AI & Security Features

The AcuPick deep-learning system helps quickly locate people and vehicles across live and recorded footage. SMD 4.0 provides intelligent human and vehicle classification, helping reduce false alarms caused by non-target movement.

The camera also supports:

• Intrusion detection

• Tripwire detection

• Human and vehicle classification

• Motion detection

• Scene change detection

• Audio detection

• Video tampering detection

• SD card error/full detection

• Network disconnection detection

• IP conflict detection

• Illegal access detection

• Voltage detection

• External alarm input

Audio & Active Deterrence

The integrated audio and deterrence system provides an additional layer of protection. When configured with supported alarm events, the camera can activate its red and blue warning lights and siren, while the built-in speaker and dual microphones support two-way communication.

Storage & Connectivity

The camera supports Micro SD storage up to 512GB, along with FTP, SFTP and NAS storage options. It supports ONVIF Profile S/G/T, making it suitable for integration with compatible NVRs and surveillance systems.

With PoE 802.3af, both network connectivity and power can be delivered through a single Ethernet cable, simplifying installation.

Outdoor Protection

The IP67-rated housing provides protection against dust and water, making the camera suitable for exposed outdoor installations. Its bullet design is particularly suitable for driveways, gates, car parks, warehouses, commercial buildings, farms, workshops and perimeter security.
