Dahua Technology WizSense IPC-HFW3441T-AS-P cámara de vigilancia IP tipo bullet interior y exterior 2688 x 1520 píxeles montaje en techo/pared

DAHUA IPC-HFW3441T-AS-P is a 4MP IR bullet IP camera designed for outdoor surveillance. It provides 4 megapixel resolution at up to 30 fps, integrated infrared illumination for night monitoring up to 20 meters, and AI-enabled analytics for intelligent motion detection and event filtering. The camera is built with an IP67-rated enclosure for reliable operation in outdoor environments and supports both DC and Power over Ethernet (PoE) power options. Physical design allows ceiling or wall mounting and a full 0–360° pan range for flexible placement.

Advantages

The camera combines high-resolution imaging with infrared night vision and on-device AI analytics to reduce false alarms and improve detection accuracy. WDR and day/night functionality maintain image detail in high-contrast scenes and varying light conditions. An integrated microphone and a built-in card reader enable local audio capture and edge storage, while alarm input/output options support integration with external detectors and systems. Protective IP67 housing and a robust bullet form factor ensure durability for perimeter and entrance monitoring.

How to use

Mount the camera on a stable surface using appropriate screws and anchors for ceiling or wall installation, orienting the lens to cover the desired field of view and using the 0–360° pan range to fine-tune framing. Connect power using a DC adapter or a PoE switch/injector and connect the Ethernet cable to the local network. Configure the camera via the Dahua web interface or supported NVR software to set resolution, frame rate, WDR, day/night settings and AI detection parameters. Insert a compatible memory card into the integrated card reader for local storage, or configure network recording to a NAS or NVR.

Recommendations

For reliable detection and optimal image quality, position the camera so primary subjects are within the 20 m effective IR range and avoid strong backlight directly facing the lens. Use WDR in scenes with high contrast and adjust white balance to match ambient lighting (Auto/Manual/Natural/Outdoor/Street lamp). When deploying multiple cameras, configure AI analytics thresholds to balance sensitivity and false alarm reduction, and use PoE for simplified cabling and centralized power management.
