Hikvision DS-2CD2446G2-I 4MP AcuSense Darkfighter IP Network Cube Camera
DS-2CD2446G2-I is a 4MP IP network cube camera featuring 2688 × 1520 resolution. This camera has a 2.8mm fixed lens, built-in mic and speaker for two-way audio, PIR and up to 10m smart IR illumination. This camera supports 12V DC or PoE (Power of Ethernet) connections for easy installation and uses the latest H.265 / H.265+ compression saving considerable bandwidth and data storage requirements.
This camera has a PIR and Acusense technology which uses a deep learning algorithm to help filter human and vehicle targets from other moving objects and reduce the number of false alarms generated.
This camera supports smart features including line crossing detection, intrusion detection, unattended baggage detection, object removal detection, face detection and scene change detection.
The camera is manufactured in all plastic construction and is suitable for indoor applications.
