Black Hikvision DS-2CD23166G3-I2UY Product Overview
The Hikvision DS-2CD23166G3-I2UY(2.8mm)(eF) in black is a 16MP AcuSense Powered-by-DarkFighter fixed turret network camera. Its 1/1.8-inch progressive-scan CMOS sensor records at up to 4608 × 3456, while the fixed 2.8mm F1.6 lens provides a 94.5° horizontal field of view.
The camera combines infrared illumination up to 40 metres, 130dB WDR, human and vehicle classification, face capture, an arrayed dual microphone and local memory-card support up to 512GB. This exact I2UY version does not have a manufacturer-stated built-in speaker, external audio input/output or alarm input/output, so it is not presented as a two-way-audio or active-deterrence model.
