Black Hikvision DS-2CD23126G3-IS2UY/SL Product Overview
The Hikvision DS-2CD23126G3-IS2UY/SL(2.8mm)(eF) in black is a 12MP AcuSense Powered-by-DarkFighter fixed turret network camera with active deterrence and integrated two-way audio. 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, external audio input/output, one alarm input and output, a white warning strobe and audible-warning capability. Infrared illumination is specified up to 30 metres. The white strobe is a warning device and is not presented as a long-range white scene illuminator.

Deterrence, Audio and Compatibility
The /SL version can link its white warning strobe, audible warning, recording and alarm output to supported events. The built-in microphones and speaker support compatible two-way communication. Advanced controls can depend on the recorder, software and firmware in use.
Confirm NVR 12MP decoding, PoE+ budget, AcuSense, two-way audio, alarm, deterrence, storage-card and mounting compatibility before ordering. Third-party integration does not guarantee access to every Hikvision-specific feature.
