Hikvision DS-2CD2346G3-IZS2UY/SL Product Overview
The Hikvision DS-2CD2346G3-IZS2UY/SL(2.8/4mm) is a 4MP AcuSense Powered-by-DarkFighter point-varifocal turret network camera with integrated two-way audio and active deterrence. Its motorised lens switches between the supported 2.8mm and 4mm focal positions, while the 1/3-inch CMOS sensor records at up to 2688 × 1520 at up to 25/30fps.
The `/SL` hardware includes two built-in microphones, a 2W speaker, external audio input/output, one alarm input/output, a white warning strobe and audible-warning capability. The camera also provides infrared illumination up to 30 metres, 130dB WDR, human and vehicle classification, local storage up to 512GB, PoE+ and IP67 plus NEMA 4X protection.

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 audio. The strobe is a warning device rather than a claimed general scene illuminator.
Confirm NVR 4MP decoding, AcuSense, lens control, PoE+ capacity, two-way audio, alarm and deterrence controls, storage-card and mounting compatibility before ordering.
