Dahua IPC-HFW2541T-ZAS-27135-S2

SKU: 6923172582157

The camera provides a maximum resolution of 2960 × 1668 pixels at 20 frames per second and also supports 2688 × 1520 pixels at 25/30 frames per second.

It features H.265 compression, which significantly reduces bitrate and saves storage space. The camera has built-in IR LED illumination with a range of up to 60 meters, enabling monitoring in complete darkness.

Features such as ROI, SMART H.264+/H.265+, and intelligent encoding allow for flexible adaptation to various network conditions and storage space.

The camera also offers advanced monitoring features, including intrusion detection, tripwire (with the ability to classify vehicles and people), and anomaly detection such as motion, image manipulation, and network issues.

Additionally, the camera features audio alarms (1 input, 1 output) and supports microSD cards up to 256 GB. Power is supplied via 12 VDC/PoE, making installation easy.

The camera is weatherproof (IP67) and has optional IK10 protection. It is equipped with a 2.7-13.5 mm vari-focal lens, providing a wide field of view.

The camera also supports features such as WDR (120 dB), HLC, BLC, digital watermarking, and intelligent motion tracking.

The Dahua IPC-HFW2541T-ZAS-27135-S2 is ONVIF-compliant and offers extensive integration with other security systems. The camera is ideal for both indoor and outdoor surveillance, ensuring high image quality and reliability in various environmental conditions.
