Dahua Bullet Camera for Surveillance HFW2431S-S-S2

Dahua HFW2431 IP camera for outdoor surveillance with a bright image sensor and 4MP resolution for brilliant videos, even under poor lighting conditions

System overview

Thanks to the improved H.265 encoding technology, the Dahua Lite series camera has an efficient video encoding capacity that saves bandwidth and storage space. This camera uses the latest Starlight technology and provides a better, more colorful picture in low-light environments. It supports SD card storage, waterproof function and dustproof function.

Wide dynamic range (WDR)

Dahua uses the advanced WDR (Wide Dynamic Range) technology. You will get clear details in the environment with strong brightness contrast. You can also get clear images in high brightness and backlit environments, bright and dark areas with a strong light source.

Intelligent video analysis (IVS)

With the advanced video algorithm, the Dahua camera supports intelligent detection like tripwire and intrusion etc.

S.265 + & H.264mart (H +)

Dahua intelligent coding technology adopts advanced algorithm for automatic stream control according to the environment and achieves higher efficiency than (H.265 & H.264). It delivers high quality video and lowers storage and transmission costs.

Crisp videos even in the dark

With the powerful IR night vision LEDs, objects are recognized without errors even in absolute darkness. Since the IR spectrum is above the color spectrum, i.e. above our field of vision, the videos shown are shown in black and white.

Local recordings also possible without a recorder

With the built-in SD card slot, the videos can be saved on a micro SD card. A recording rule can also be set with a calendar function, so that, for example, recording is only made on weekdays or only when movement is detected.
