Dahua IPC-HFW3449T1-AS-PV-PRO 4MP TiOC PRO WizColor Bullet
Description
IPC-HFW3449T1-AS-PV-PRO is a 4 MP WizColor TiOC PRO bullet camera from the Dahua WizSense 3 series. Beyond video it carries a siren, red and blue warning lights, a built-in speaker and two microphones, so it can record an intruder and also warn them off, with two-way talk to a person at the monitoring desk.
A bullet camera that deters as well as records
Dahua lists a sound and light alarm (red and blue lights) and active deterrence in the power figures, and the camera has one alarm input and one alarm output, one audio input and one audio output on RCA ports. When an intrusion or tripwire rule fires, the siren and lights can run while the operator speaks through the speaker, which suits unattended gates, solar farms, depots and construction sites.
Two fixed lenses are offered: 2.8 mm (111 degrees horizontal) and 3.6 mm (95 degrees). The multi-core lights reach 40 m infrared and 40 m warm light with the 2.8 mm lens, and 60 m infrared and 50 m warm light with the 3.6 mm lens. The camera is 288.4 mm long and weighs 1.0 kg.
Key features from the Dahua datasheet
- 4 MP 1/1.8 inch sensor, F1.0, 0.0001 lux colour, 130 dB WDR
- Four multi-core (IR plus warm) lights, 60 m IR with the 3.6 mm lens
- Siren, red and blue light, speaker, dual microphone, two-way talk
- Perimeter protection with Large-Scale AI Models, SMD 4.0, AcuPick, AI SSA, face detection
- 1 alarm in and out, 512 GB micro SD, 12 VDC or PoE+, IP67

Selection and ordering guide
The datasheet ordering code is DH-IPC-HFW3449T1-AS-PV-PRO (4MP WizColor TiOC PRO Fixed-focal Bullet WizSense Network Camera). The letters AS and PV in the code line up with the audio, alarm and active-deterrence features listed in the datasheet; this reading is derived, not a Dahua definition.
The siren and light draw is included in the 14.3 W PoE maximum, so use an 802.3at (PoE+) port when deterrence is active; the datasheet specifies PoE+ rather than basic PoE for this model.
Installation and operation notes
Dahua lists the DH-PFA130-E waterproof junction box, DH-PFA135 junction box and G3416GW G3/4 inch water joint for cabling, and DH-PFA152-E and DH-PFA151 brackets for pole and corner mounting. The one-tap arming and disarming feature and the SMD area in the warm-light zone are configured in the web interface. Test the speaker volume on site before relying on it for deterrence, and follow local rules on audio warnings.
Applications in Oman and the GCC
Unattended sites where a human response is minutes away benefit from a camera that can speak and flash: remote pump stations, storage yards, solar plants, construction compounds and shop frontage. The temperature rating to +60 C and IP67 enclosure are as printed; basic corrosion class means coastal sites need a separate check.
