Black Hikvision DS-2CD2746G2H-IPTRZS2U/SL Product Overview
The black Hikvision DS-2CD2746G2H-IPTRZS2U/SL is a 4MP motorised PTRZ varifocal dome network camera for installations that require a dark-finish housing, detailed imaging and remote optical adjustment. Its 1/1.8-inch progressive-scan CMOS sensor records at up to 2688 × 1520, and the 2.8–12mm motorised lens can be adjusted from a broad overview to a narrower view of a selected area.
Powered-by-DarkFighter technology supports low-light imaging, while infrared illumination provides a manufacturer-rated range of up to 40 metres. AcuSense deep-learning technology can classify human and vehicle targets for supported perimeter events. The /SL version includes a white strobe, audible warning, built-in dual microphones, built-in speaker and audio and alarm interfaces.
Key Benefits
-
Black metal finish: suited to installations where a darker camera housing is required.

-
Remote PTRZ setup: pan, tilt, rotation and zoom can be adjusted without repeatedly reopening the dome.
-
Motorised 2.8–12mm lens: supports both wider scene coverage and a tighter view of the target area.
-
DarkFighter low-light imaging: supports useful imaging in challenging lighting conditions.
-
AcuSense classification: distinguishes human and vehicle targets for compatible perimeter events.
-
Event-linked deterrence: the /SL hardware can activate a white strobe and audible warning.

Detection, Audio and Active Deterrence
The camera supports perimeter-protection functions including line crossing, intrusion, region entrance and region exit. Human and vehicle classification can be applied to supported events to help focus notifications on selected target types. Accuracy depends on the installation, target size, scene conditions and event configuration.
The /SL model provides a white strobe and audible warning that can be linked to supported events. Built-in dual microphones capture sound, and the built-in speaker supports two-way communication and warning playback. Audio and alarm input/output interfaces are also available for compatible external devices.
Installation and Compatibility
The motorised PTRZ assembly allows remote adjustment of pan, tilt, rotation and focal length through compatible Hikvision software or a supported recorder. This is useful where the camera is difficult to reach or where the final view needs to be refined after mounting.
Use a suitable IEEE 802.3at PoE+ source or a correctly rated 12V DC supply. Before ordering, confirm NVR resolution support, available PoE power, analytics compatibility, audio and alarm functionality, storage-card support and the correct mounting accessory. ONVIF Profiles S, G and T support interoperability, but third-party systems might not expose every Hikvision feature.
Frequently Asked Questions
Is this the black version?
Yes. This listing is for the black-finish model identified in the product title.
What is the maximum resolution?
The maximum resolution is 2688 × 1520, commonly described as 4MP.
What can be adjusted remotely?
Compatible software or a supported recorder can adjust pan, tilt, rotation and the 2.8–12mm motorised zoom lens.
Does it produce colour images in complete darkness?
Powered-by-DarkFighter helps in low light, while built-in infrared provides monochrome night imaging in darkness. Results depend on available light and settings.
What is the infrared range?
Hikvision specifies up to 40 metres. Real-world distance varies with the scene, focal length, mounting and reflective surfaces.
Can it classify people and vehicles?
Yes. AcuSense supports human and vehicle classification for compatible perimeter-protection events.
Does it include active deterrence?
Yes. The /SL version includes a white strobe and audible warning.
Does it support local recording?
Yes. It supports compatible microSD, microSDHC and microSDXC cards up to 512GB. The card is normally supplied separately.
Can it use PoE?
Yes. It supports IEEE 802.3at PoE+, Class 4, or a correctly rated 12V DC power supply.
Can it be installed outdoors?
The metal enclosure is rated IP66 and IK10. Correct sealing, mounting, cable protection and environmental installation remain necessary.
