The DS-2CD2T87G3-LIS2UY/SL is an 8MP (3840 x 2160) fixed bullet camera with a 1/1.8" progressive scan CMOS sensor and an F1.0 2.8mm lens giving a 108.8° horizontal field of view. ColorVu technology and HikAI-ISP noise reduction deliver 24/7 colour imaging, with a minimum illumination of 0.0005 lux. Smart Hybrid Light combines IR and white light with three supplemental lighting modes and a range of up to 60m. Deep learning classification of people and vehicles drives line crossing, intrusion and region entrance and exit alarms, which can trigger the built-in white strobe light and audible warning. A built-in arrayed dual microphone and speaker provide real-time two-way audio, alongside two alarm inputs, two alarm outputs and a microSD slot for cards up to 512GB. The metal housing is rated IP67 with NEMA 4X anti-corrosion protection, offers 130 dB WDR and EIS, and runs on PoE (802.3at) or 12 VDC from -30 to 60°C.
