Dahua Technology WizSense IPC-HDBW2449E-S-IL-0280B Câmara de segurança Dome Câmara de vigilância IP Exterior 2688 x 1520 píxeis Teto/Parede/Poste

DAHUA IPC-HDBW2449E-S-IL-0280B is a 4 MP IP dome camera with a fixed 2.8 mm lens, providing up to 2688 × 1520 resolution at 30 fps. The camera has a metal housing with IP67 and IK10 ratings for outdoor use and can be mounted on ceilings, walls or poles. Power is supplied via DC or PoE. Video compression supports H.264, H.265 and M-JPEG; additional features include 120 dB wide dynamic range (WDR), 3D noise reduction, IR and white LEDs for night illumination up to 30 m, a built-in microphone and local storage via microSD card (up to 256 GB).

Advantages

The camera combines robust mechanical protection (metal housing, IK10) and weather resistance (IP67) with flexible installation options and PoE/DC power support. It delivers high-resolution 4 MP video with wide dynamic range and multiple compression formats for efficient storage and streaming, while onboard IR/white lighting and noise-reduction technologies improve image quality in low-light conditions. Integrated microphone and microSD support enable local audio recording and edge storage.

How to use

Install the dome camera on a suitable ceiling, wall or pole using appropriate fasteners. Connect power via a 12 V DC adapter or use PoE (IEEE 802.3af) through the Ethernet port. Insert a compatible microSD card (up to 256 GB) for local recording if required. Access live video and configure settings through a web browser or the supported management software (Smart PSS Lite, DSS, DMSS, DoLynk Care). Adjust orientation and any software-based image settings such as WDR, noise reduction and exposure for the installation environment.

Recommendations

For reliable outdoor operation, mount the camera under a sheltered location when possible, ensure the network and PoE supply meet required standards, and format the microSD card in the camera before first use. Regularly check firmware updates and configure secure network credentials to protect remote access.
