Equipped with the Transducter CMOS 1/2.7", provides a clear Picture even under difficult lighting conditions, thanks to the sensitivity from 0 lux with the IR bulb on.
By Camera offers a wide range of traffic: Mr. 0°–355°, tilt 0°–65° and rotation 0°–355°, which allows precise monitoring of large spaces.
Smart Image Analysis (IVS) features include detection of intrusion and tripwire, automatically classifying objects as vehicles or people.
Technology Smart H265+ optimizes Throughput Rate and memory consumption, offering high compression while maintaining image quality.
By Camera supports two Video streams, with a maximum resolution of 3840 × 2160@20 kl./s for the main stream and lower resolutions for the sub-stream.
Additional Functions include WDR 120 dB, 3D NR, BLC/HLC and the possibility of day/night operation with automatic ISO regulation.
For Camera to be weather resistant (IP67, IK10) and to operate at temperatures from -40°C to +60°C.
PoE Power Supply 802.3af simplifies installation, and low Power consumption (up to 5.4 W) makes it energy-efficient.
Dahua IPC-HDBW2841E-S-0280B is an ideal solution for monitoring systems requiring high quality images and advanced analytical functions.
Intrusion, tripwire (the two functions support the classification and accurate detection of vehicle and human)
