Description
Hikvision DS-2CD23166G3-I2UY Product Overview
The Hikvision DS-2CD23166G3-I2UY(2.8mm)(eF) 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 provides infrared illumination up to 40 metres, 130dB WDR and human and vehicle classification for supported motion and perimeter events. The 2U hardware includes an arrayed dual microphone for audio capture, and compatible memory cards up to 512GB are supported. This exact I2UY model does not have a manufacturer-stated speaker, external audio input/output or alarm input/output.
Key Benefits

High-Resolution Frame Rate
The full 4608 × 3456 stream runs at 12.5fps in 50Hz mode or 15fps in 60Hz mode. The camera can provide 20fps at 4608 × 2592 and up to 25fps or 30fps at supported lower resolutions. This distinction should be considered where smooth motion is more important than maximum pixel count.
Audio and Compatibility
The camera includes dual microphones for audio capture but has no stated speaker, external audio output or alarm interface. It must not be marketed as a two-way-audio or active-deterrence model.
Confirm NVR 16MP decoding, required frame rate, bandwidth, PoE, analytics, storage and mounting compatibility before ordering. NEMA 4X indicates moderate anti-corrosion protection rather than unrestricted severe-environment suitability.
