Hikvision DS-2CD2786G2H-IPTRZS2U/SL Product Overview
The Hikvision DS-2CD2786G2H-IPTRZS2U/SL is an 8MP AcuSense motorised PTRZ varifocal dome network camera for installations that require detailed 4K video and remote optical adjustment. Its 1/1.8-inch progressive-scan CMOS sensor records up to 3840 × 2160, while the 2.8–12mm motorised lens supports remote pan, tilt, rotation and zoom adjustment after the camera has been mounted.
Powered-by-DarkFighter low-light technology, 120dB WDR and infrared illumination up to 40 metres support monitoring across difficult lighting conditions. Deep-learning analytics can classify human and vehicle targets for supported events. The /SL version also includes dual-array microphones, a built-in speaker, active white strobe and audible warning, plus audio and alarm interfaces.
Key Benefits
-
8MP recording: maximum 3840 × 2160 video provides detailed live viewing and playback.
-
Remote PTRZ adjustment: pan, tilt, rotation and optical zoom can be refined remotely, reducing repeated access to the dome.
-
Low-light performance: DarkFighter technology and 0.0008-lux colour sensitivity help retain image detail before infrared mode is required.
-
Infrared coverage: built-in 850nm IR illumination has a manufacturer-rated range of up to 40 metres.
-
Target classification: human and vehicle filtering is available for supported motion and perimeter events.
-
Active deterrence: the /SL hardware can trigger a white strobe and audible warning through compatible event rules.
-
Audio capability: dual-array microphones, a built-in speaker and external audio input/output support recording and two-way communication.
-
Outdoor and impact protection: the metal housing is rated IP66 and IK10.

Detection, Audio and Deterrence
The camera supports motion, line-crossing, intrusion, region-entry and region-exit events. Supported rules can filter for human and vehicle targets. Event actions can include recording, capture, alarm output, audible warning and strobe-light flashing when configured with compatible Hikvision equipment.
Dual-array microphones provide audio capture, while the built-in speaker supports warning playback and two-way communication. Separate line-level audio and alarm interfaces are also available for compatible external devices.
Installation and Compatibility
PTRZ adjustment allows the installed viewing direction and focal length to be refined through compatible Hikvision software or a supported recorder. The camera requires a suitable IEEE 802.3at PoE+ source or correctly rated 12V DC supply. Check PoE budget, recorder decoding, analytics, audio, alarm, memory-card and mounting compatibility before ordering.
ONVIF Profiles S, G and T are supported for third-party integration, but advanced analytics, deterrence and remote PTRZ functions may depend on the recorder or software platform.
Frequently Asked Questions
What is the maximum resolution?
The camera records at up to 3840 × 2160, commonly described as 8MP or 4K.
What does PTRZ provide?
PTRZ provides motorised pan, tilt, rotation and zoom adjustment for easier setup and later maintenance.
Does it use ColorVu?
No. This is an AcuSense powered-by-DarkFighter infrared model, not the ColorVu version.
How far does the infrared light reach?
The official specification states up to 40 metres. Actual performance depends on the scene and installation.
Can it classify people and vehicles?
Yes, for supported motion and perimeter-protection events.
Does it have active deterrence?
Yes. The /SL version includes a white strobe and audible warning.
Does it support two-way audio?
Yes. It has dual microphones, a built-in speaker and line-level audio input/output.
What memory-card capacity is supported?
Compatible microSD, microSDHC and microSDXC cards up to 512GB are supported.
Can it run from PoE?
Yes. It requires IEEE 802.3at PoE+, Class 4, or a correctly rated 12V DC supply.
Is it suitable for outdoor use?
The housing is rated IP66 and IK10. Hikvision states no specialist anti-corrosion protection, so coastal or chemically aggressive sites require additional assessment.
