Hikvision DS-2CD23126G3-IS2UY/SL Product Overview
The Hikvision DS-2CD23126G3-IS2UY/SL(2.8mm)(eF) is a 12MP 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 × 2592, while the fixed 2.8mm F1.6 lens provides a 94.2° 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. The exact datasheet specifies infrared illumination up to 30 metres. The white strobe is a warning device and is not presented as a 30-metre scene illuminator.
Key Benefits
-
12MP evidence: captures up to 4608 × 2592 at up to 20fps.
-
DarkFighter low-light imaging: supports useful detail under limited illumination.
-
30m infrared: built-in IR supports monochrome monitoring in darkness.
-
AcuSense classification: supported motion and perimeter events can distinguish human and vehicle targets.
-
Integrated two-way audio: dual microphones and a 2W speaker support compatible communication and warning playback.
-
Active deterrence: a white strobe and audible warning can be linked to supported events.
-
External integration: one audio input/output and one alarm input/output are provided.
-
Protected housing: IP67 and NEMA 4X moderate anti-corrosion protection.

Active Deterrence and Audio
The white strobe and audible warning can be linked to supported events. The white strobe is intended as a visible warning signal and should not be represented as general white-light scene illumination. Warning behaviour, volume and event linkage depend on firmware and configuration.
The dual microphones and built-in speaker support compatible two-way audio. External line audio and alarm interfaces are also available. Audio quality and warning effectiveness depend on mounting, environment and network conditions.
Installation and Compatibility
Confirm NVR 12MP decoding, PoE+ budget, AcuSense, two-way audio, alarm and strobe controls, memory-card compatibility and mounting hardware before ordering. Third-party ONVIF integration does not guarantee access to every deterrence or analytics control.
