Hikvision DS-2CD2546G2-IS 4mm Product Overview
The Hikvision DS-2CD2546G2-IS(4mm)(C) is a 4MP AcuSense Powered-by-DarkFighter fixed mini dome network camera with a narrower 4mm fixed lens. Its 1/3-inch progressive-scan CMOS sensor records at up to 2688 × 1520, while the F1.4 lens provides an 82.8° horizontal field of view.
The camera includes infrared illumination up to 30 metres, 120dB WDR, human and vehicle classification for supported events and face capture. The -IS hardware provides a built-in microphone, one external line audio input and output, one alarm input and output and a memory-card slot supporting compatible cards up to 512GB.

Detection, Audio and Storage
AcuSense classification can focus supported motion and perimeter events on human and vehicle targets. Face capture is also available. Performance depends on target size, camera angle, lighting and configuration.
The built-in microphone captures audio, and the separate line input/output supports compatible external equipment. Hikvision does not state a built-in speaker. Compatible memory cards up to 512GB are supported and are normally sold separately.
Installation and Compatibility
The fixed 4mm lens provides a tighter view than the 2.8mm version and does not provide optical zoom. The dome angle is adjusted physically during installation. Confirm that the 4mm field of view suits the site before ordering.
Confirm NVR resolution, AcuSense, audio and alarm, PoE, memory-card and mounting compatibility before ordering.
