The DS-2SE4C425MWG-E/14 TandemVu network speed dome combines a fixed 4MP ColorVu bullet channel with a separate 4MP PTZ channel, allowing security teams to maintain wide-area awareness while simultaneously viewing detailed activity at long range.
The fixed bullet channel uses an F1.0 aperture and white light illumination up to 30 meters to support full-color low-light monitoring. The PTZ channel uses Powered-by-DarkFighter technology, 25× optical zoom, 16× digital zoom, and infrared illumination up to 100 meters for detailed observation across large outdoor sites.
Deep learning-based human and vehicle classification supports line crossing, intrusion, region entrance, and region exit events. Smart linkage functions can coordinate the panoramic channel and PTZ channel for linked tracking capture, while face capture and regional people counting add advanced monitoring capabilities for large commercial properties.
Two built-in microphones and an integrated speaker support real-time two-way audio. The PTZ channel also supports strobe light and audio alarm linkage for active deterrence. Additional features include Audio I/O, alarm I/O, onboard microSD storage up to 512 GB, IEEE 802.3at PoE+, ONVIF Profile S/G/T compatibility, and IP67 weather protection.
