By Camera, it offers a 3840x2160 pixel image quality with a 1/2.8" CMOS converter, providing clear and detailed recordings even in difficult lighting conditions.
With IR technology up to 60 meters, To make Camera effectively monitor the Area also in total darkness.
Motorized variable-focal lens with a focal length of 2.7-13.5 mm allows flexible adjustment of the field of vision from a wide angle of 30° to a narrower 109° horizontal.
By Camera supports Smart Functions Image Analysis (IVS), such as intruder detection or PROTECTION perimeter, which increases monitoring efficiency.
Dahua IPC-HFW3841T-ZAS-27135 supports video compression H265/H264, optimizing Throughput Rate and memory consumption.
Additionally, By Camera offers Functions such as WDR 120dB, 3D NR, defog and region of interest (ROI), allowing for precise adjustment of settings to the user's needs.
Durable IP67-class enclosure guarantees resistance to atmospheric conditions, and Temperature Range work from -30°C to +60°C provides Reliability in various environments.
To make Camera compatible with ONVIF protocols and support integration with other manufacturers' systems, making it a universal solution for professional monitoring.
