Designed for indoor business areas where video, audio, and temperature-based motion sensing are needed in one compact device, the DS-2CD2443G2-I combines 4MP AcuSense imaging, PIR detection, two-way audio, and local edge recording in a fixed cube camera design.
Deep learning-based human and vehicle classification helps focus video events on relevant targets, while the integrated passive infrared sensor detects human body heat within a range of up to 8 meters. Using video analytics and PIR sensing together can provide additional event context in offices, reception areas, retail spaces, stockrooms, and other controlled indoor environments.
The built-in microphone and speaker support real-time two-way communication through compatible surveillance platforms. The speaker can also provide an audible warning when configured with supported event actions. For low-light monitoring, Smart IR illumination provides visibility up to 10 meters without requiring continuous room lighting.
The camera supports 120 dB WDR, H.265+ compression, face detection, onboard microSD storage up to 512 GB, IEEE 802.3af PoE, and ONVIF Profile S/G/T integration. Its compact form factor makes it a practical option for indoor commercial locations that need video verification, audio communication, and localized motion awareness.
