Hikvision DS-2CD2746G2H-IPTRZS2U/SL(2.8-12mm) 4MP AcuSense Active-Deterrence PTRZ Dome Camera

Hikvision DS-2CD2746G2H-IPTRZS2U/SL Product Overview

The Hikvision DS-2CD2746G2H-IPTRZS2U/SL is a 4MP motorised PTRZ varifocal dome network camera for security installations that require detailed imaging, remote adjustment and intelligent event filtering. Its 1/1.8-inch progressive-scan CMOS sensor records at up to 2688 × 1520, while the 2.8–12mm motorised lens allows the viewing angle and zoom level to be adjusted after installation.

Powered-by-DarkFighter technology supports low-light imaging, and the built-in infrared illumination has a manufacturer-rated range of up to 40 metres. AcuSense deep-learning technology can classify human and vehicle targets for supported perimeter-protection events. The /SL version also includes a white strobe and audible warning, together with built-in dual microphones, a built-in speaker and audio and alarm interfaces.

Key Benefits

• Detailed 4MP video: records at up to 2688 × 1520 for clear live viewing and playback.
• Remote PTRZ adjustment: motorised pan, tilt, rotation and zoom simplify commissioning and later scene adjustments.
• Flexible focal length: the 2.8–12mm motorised lens can provide a wider overview or a narrower view of a selected area.
• Improved low-light performance: Powered-by-DarkFighter technology and a maximum F1.2 aperture support imaging in difficult lighting.
• Infrared night monitoring: built-in IR illumination supports viewing in darkness at distances up to 40 metres.
• Target classification: AcuSense can distinguish human and vehicle targets for compatible perimeter events.
• Active deterrence: the /SL model can trigger a white strobe and audible warning when linked to supported events.
• Protected housing: the metal enclosure is rated IP66 for water and dust resistance and IK10 for impact resistance.

Technical Specifications

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 the selected target types. Detection performance depends on camera position, scene conditions, target size and configuration.

The /SL hardware includes a white strobe and an audible warning that can be linked to supported events. Built-in dual microphones capture sound, while the built-in speaker supports two-way communication and warning playback. Audio and alarm input/output interfaces are also available for compatible external equipment.

Installation and Compatibility

The PTRZ mechanism allows the installer to adjust pan, tilt, rotation and focal length remotely through compatible Hikvision software or a supported recorder. This can reduce the need to reopen or manually reposition the dome during setup and later maintenance.

The camera can be powered from a suitable IEEE 802.3at PoE+ source or a correctly rated 12V DC supply. Confirm the recorder's camera-resolution support, PoE budget, analytics compatibility, audio and alarm support, memory-card compatibility and required mounting accessory before ordering. ONVIF support can assist third-party integration, but it does not guarantee that every analytics or deterrence function will be available on every recorder.

Frequently Asked Questions

What is the maximum video resolution?

The maximum resolution is 2688 × 1520, commonly described as 4MP.

What does PTRZ mean?

PTRZ refers to motorised pan, tilt, rotation and zoom adjustment. These settings can be changed remotely through compatible software or a recorder.

Does the camera provide colour video in complete darkness?

The camera uses Powered-by-DarkFighter technology for low-light imaging and infrared illumination for darkness. Infrared night images are normally monochrome; results depend on available light and configuration.

How far does the infrared illumination reach?

Hikvision specifies an IR range of up to 40 metres. Actual usable distance depends on the scene, mounting height, lens setting and surface reflectivity.

What does AcuSense do?

AcuSense applies deep-learning human and vehicle classification to supported perimeter-protection events. It does not eliminate every unwanted alert, and correct installation and configuration remain important.

Does it have active deterrence?

Yes. The /SL version includes a white strobe and audible warning that can be linked to supported events.

Does it support two-way audio?

Yes. It has built-in microphones and a built-in speaker, together with audio input and output interfaces.

Can it record to a memory card?

Yes. It supports compatible microSD, microSDHC and microSDXC cards up to 512GB. The card is normally sold separately.

Can it be powered by PoE?

Yes. It supports IEEE 802.3at PoE+, Class 4, or a correctly rated 12V DC supply.

Is it suitable for outdoor installation?

The metal housing is rated IP66 and IK10. Installation must still follow Hikvision's sealing, cable-entry, mounting and environmental instructions.
