Equipped with Image Sensor 1/2.8" CMOS, it provides clear and detailed Picture even in difficult lighting conditions.
Thanks to the IR Vari-focal By Camera technology, it offers a focal variable (2.7 mm–13.5 mm), allowing a flexible adjustment of the field of view from 109° to 30° horizontally and from 56° to 17° vertically.
Smart Image Analysis (IVS) features include detection of intruders, perimeter protection and recognition of people and vehicles, which increases the effectiveness of monitoring.
By Camera supports video H265/H264 compression, offering efficient data transmission with minimal bandwidth.
Additional Functions include WDR 120 dB (Wide Dynamic Range), Technology defog to improve visibility in haze conditions and Electronic Image Stabilization (EIS).
For Camera to be equipped with integrated Microphone and Speaker Unit, allowing two-way communication.
Resistance to atmospheric conditions (IP67) and vandal-resistant housing (IK10) make it ideal for outdoor applications.
PoE Power Supply (802.3af) simplifies installation, and the wide Temperature Range of work (-30°C to +60°C) guarantees Reliability under different climatic conditions.
Dahua IPC-HDBW3841R-ZAS-27135 is a comprehensive solution for professional monitoring, combining high image quality with advanced analytical functions.
