Its 1\/3-inch progressive-scan CMOS sensor records at up to 2688 × 1520, while the fixed 2.8mm F1.0 lens provides a wide 100.2° horizontal field of view.\u003c\/p\u003e\u003cp\u003eThe camera combines a manufacturer-rated minimum colour illumination of 0.001 lux, infrared illumination up to 30 metres and 120dB WDR. Deep-learning analytics support human and vehicle classification for compatible motion and perimeter events. It also provides face capture, scene-change detection and local memory-card support up to 512GB. Hikvision does not state a built-in speaker, external audio input\/output or alarm input\/output for this exact IU model.\u003c\/p\u003e\u003ch2\u003eKey Benefits\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDetailed 4MP video:\u003c\/strong\u003e records at up to 2688 × 1520 at 25fps in 50Hz mode or 30fps in 60Hz mode.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide scene coverage:\u003c\/strong\u003e the fixed 2.8mm lens provides a 100.2° horizontal view.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDarkFighter low-light imaging:\u003c\/strong\u003e the F1.0 aperture supports useful colour detail in very low illumination.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInfrared night monitoring:\u003c\/strong\u003e built-in 850nm IR has a manufacturer-rated range of up to 30 metres.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAcuSense classification:\u003c\/strong\u003e supported events can distinguish human and vehicle targets.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacklight handling:\u003c\/strong\u003e 120dB WDR helps retain detail where bright and dark areas appear together.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt-in audio capture:\u003c\/strong\u003e the integrated microphone records sound without implying speaker playback.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtected metal housing:\u003c\/strong\u003e the enclosure is rated IP67 for water and dust resistance.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e4MP maximum resolution of 2688 × 1520\u003c\/li\u003e\n\u003cli\u003e1\/3-inch progressive-scan CMOS sensor\u003c\/li\u003e\n\u003cli\u003e2.8mm fixed focal lens with F1.0 aperture\u003c\/li\u003e\n\u003cli\u003e100.2° horizontal, 54.7° vertical and 119.7° diagonal field of view\u003c\/li\u003e\n\u003cli\u003eMinimum colour illumination of 0.001 lux at F1.0 with AGC enabled\u003c\/li\u003e\n\u003cli\u003eInfrared illumination up to 30 metres\u003c\/li\u003e\n\u003cli\u003e120dB true wide dynamic range\u003c\/li\u003e\n\u003cli\u003eH.265+, H.265, H.264+ and H.264 compression\u003c\/li\u003e\n\u003cli\u003eHuman and vehicle classification for supported events\u003c\/li\u003e\n\u003cli\u003eLine crossing, intrusion, region entrance and region exit support\u003c\/li\u003e\n\u003cli\u003eFace-capture and scene-change-detection support\u003c\/li\u003e\n\u003cli\u003eBuilt-in microphone with environmental-noise filtering\u003c\/li\u003e\n\u003cli\u003eMemory-card support up to 512GB\u003c\/li\u003e\n\u003cli\u003e12V DC or IEEE 802.3af PoE power\u003c\/li\u003e\n\u003cli\u003eIP67 weather resistance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003ctd\u003eDS-2CD2346G2H-IU(2.8mm)(eF)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCamera type\u003c\/th\u003e\n\u003ctd\u003eFixed turret network camera\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eImage sensor\u003c\/th\u003e\n\u003ctd\u003e1\/3-inch progressive-scan CMOS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaximum resolution\u003c\/th\u003e\n\u003ctd\u003e2688 × 1520\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaximum frame rate\u003c\/th\u003e\n\u003ctd\u003e25fps at maximum resolution in 50Hz mode;
