X1281-V 4K Vehicle Recognition Box Camera

Features
 1/1.8" progressive scan CMOS image sensor
 Built-in NPU neural network engine, greatly improving the
performance of deep learning algorithms
 AI-based scene adaptation. The camera can detect scenarios
in real time and make targeted setting optimization to
improve imaging quality.
 Intelligent object detection algorithms based on deep
learning. The camera can detect 50 objects at a time,
including motor vehicles, non-motor vehicles, and
pedestrians.
 Software-defined camera, supporting online loading and
upgrade of algorithms
 Extra265 intelligent encoding, reducing 70% of the
requirements on storage and bandwidth resources
 Area cropping, viewing fine details through limited
bandwidth
 Stream smoothing, meeting various requirements for video
quality and fluency
 Traffic shaping, enabling precise control over instantaneous
burst of video streams and delivering smooth video without
packet loss
 TCP acceleration, enabling the network to carry video
streams of higher quality
 PoE and AC/DC power supplies
