Hikvision DS-2CD2786G2H-IPTRZS2U/SL Black Product Overview
The black Hikvision DS-2CD2786G2H-IPTRZS2U/SL is an 8MP AcuSense PTRZ varifocal dome camera with remote motorised positioning and a 2.8–12mm optical lens. It records at up to 3840 × 2160 from a 1/1.8-inch progressive-scan CMOS sensor and is intended for professional installations that need remote setup, strong low-light imaging and active event response.
Powered-by-DarkFighter technology, 120dB WDR and infrared illumination up to 40 metres address low-light and high-contrast scenes. Human and vehicle classification is available for supported events. The /SL version adds dual-array microphones, a built-in speaker, a white strobe, audible warning and external audio/alarm interfaces.

Event Response and Audio
Supported event rules can use human and vehicle classification and can trigger recording, image capture, alarm output, audible warning or strobe-light flashing. Audio is captured by the dual-array microphones, and the built-in speaker supports live communication and warning playback.
Installation and Compatibility
Use a compatible PoE+ source or 12V DC supply and confirm the recorder's 8MP decoding, analytics, audio, alarm and PTRZ support. ONVIF can provide basic third-party integration, but advanced camera functions may require Hikvision software or compatible Hikvision recorder firmware.
