Câmara de vigilância IP DAHUA IPC-HFW2449T-ZAS-IL — 4 MP, zoom motorizado 2,7–13,5 mm, IP67/IK10, PoE, IR/LEDs brancos

The Dahua Technology IPC-HFW2449T-ZAS-IL Bullet is an IP security camera designed for indoor and outdoor surveillance. It delivers up to 4 MP resolution (2688 × 1520) with a 1/2.9" CMOS sensor, supports wired and wireless Ethernet, and provides long-range night vision with both IR and warm white light. The camera integrates Dahua WizSense AI features — including human and vehicle detection — and offers protection against dust and water (IP67) and a wide input voltage tolerance for stable outdoor operation.

Advantages

This camera combines full-color imaging at very low illuminance with Smart Dual Light technology that switches between IR and white light to capture full-color video of key events while reducing light pollution. Smart H.265+/H.264+ encoding and ROI support reduce storage and bandwidth requirements. Built-in intelligent functions such as SMD Plus and perimeter protection improve alarm accuracy by distinguishing humans and vehicles. The device is weatherproof (IP67) and supports local storage via Micro SD up to 256 GB.

Suitable for

• Outdoor perimeter and property surveillance
• Indoor monitoring of entrances, corridors, and lobbies
• Vehicle and pedestrian detection at parking lots and driveways
• Locations requiring long-range night monitoring (up to 60 m IR/white light)

How to use

Install the camera on a stable ceiling or wall mount at the desired surveillance position, ensuring the lens has an unobstructed view. Connect to power and network via wired Ethernet or configure wireless settings according to the Dahua setup procedure. Configure resolution, frame rate and encoding (Smart H.265+/H.264+) in the camera web interface or NVR to balance image quality and storage. Set up perimeter protection rules or SMD Plus zones to detect and classify human and vehicle targets and adjust alarm inputs/outputs as needed.

Recommendations

For reliable outdoor performance, mount the camera under minimal exposure to direct rain and sunlight when possible, use a stable power supply within the supported voltage range, and enable Smart H.265+ encoding to reduce bandwidth and storage. Regularly check the Micro SD card status and firmware updates to maintain detection accuracy and overall system stability.
