Hikvision DS-2CD23166G3-IS2UY/SL Product Overview
The Hikvision DS-2CD23166G3-IS2UY/SL(2.8mm)(eF) is a 16MP AcuSense Powered-by-DarkFighter fixed turret network camera with integrated two-way audio and active deterrence. 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 /SL hardware includes an arrayed dual microphone, a 2W built-in speaker, one external audio input and output, one alarm input and output, a white warning strobe and audible-warning capability. Infrared illumination is specified up to 30 metres. The strobe is a warning device and is not described as general long-range scene illumination.
Key Benefits
-
16MP evidence: captures up to 4608 × 3456 for high-detail monitoring.
-
DarkFighter low-light imaging: supports useful detail under limited illumination.
-
30m infrared: built-in IR supports monochrome monitoring in darkness.

Resolution, Deterrence and Audio
Full 16MP recording runs at 12.5fps in 50Hz mode or 15fps in 60Hz mode. The camera can provide 20fps at 4608 × 2592 and higher frame rates at supported lower resolutions. Recorder capability and required motion smoothness should be checked before choosing the recording profile.
The /SL model can link its white strobe and audible warning to supported events. The dual microphones and speaker support compatible two-way audio, while line audio and alarm interfaces support external equipment.
Installation and Compatibility
Confirm NVR 16MP decoding, required frame rate, PoE+ budget, AcuSense, two-way audio, alarm and strobe controls, storage and mounting compatibility. Advanced functions might require compatible Hikvision firmware or software.
