Hikvision DS-2CD23126G3-I2UY Product Overview
The Hikvision DS-2CD23126G3-I2UY(2.8mm)(eF) is a 12MP AcuSense Powered-by-DarkFighter fixed turret network camera. 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 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, while the memory-card slot accepts compatible cards up to 512GB. This exact I2UY model does not have a manufacturer-stated built-in speaker, external audio input/output or alarm input/output.

High-Resolution Frame Rate and Detection
The camera records its full 4608 × 2592 resolution at up to 20fps. Up to 25fps or 30fps is available at supported lower resolutions, depending on the 50Hz or 60Hz setting. Recorder decoding capability, display resolution and network bandwidth should be checked where full 12MP recording is required.
AcuSense classification can focus supported motion and perimeter events on human and vehicle targets. Face capture is also available. Detection performance depends on target size, camera angle, lighting, scene conditions and configuration.
Audio, Storage and Compatibility
The built-in dual-microphone array captures audio. No built-in speaker or external audio and alarm interfaces are stated for this exact I2UY version, so the page does not claim two-way audio or active deterrence.
Confirm NVR 12MP decoding, event support, PoE capacity, memory-card compatibility and mounting accessories before ordering. NEMA 4X denotes moderate anti-corrosion protection and does not make the camera suitable for every severe marine or chemical environment.
