Hikvision DS-2CD2666G2H-IZS Product Overview
The Hikvision DS-2CD2666G2H-IZS(2.8-12mm) is a 6MP Powered-by-DarkFighter motorised varifocal bullet network camera. Its 1/1.8-inch progressive-scan CMOS sensor records at up to 3200 × 1800, while the 2.8–12mm motorised lens supports remote zoom and focus through compatible Hikvision software or a supported recorder.
The camera combines a manufacturer-rated minimum colour illumination of 0.0008 lux at F1.2, infrared illumination up to 60 metres and 120dB WDR. Deep-learning analytics support human and vehicle classification for compatible motion and perimeter events. It also provides line-level audio input/output, alarm input/output and memory-card support up to 512GB. Hikvision does not state a built-in microphone or speaker for this exact model.

Low-Light Imaging and Detection
Powered-by-DarkFighter technology and the F1.2 lens support colour imaging in very low light. When available light is insufficient, the infrared illuminator provides monochrome imaging. Hikvision specifies an IR range of up to 60 metres, although practical performance depends on focal length, mounting, surfaces and scene conditions.
Deep-learning analytics can classify human and vehicle targets for supported motion and perimeter-protection events. Face capture and scene-change detection are also supported. Detection accuracy depends on target size, camera angle, lighting, scene conditions and correct configuration.
Audio, Alarm and Storage
The camera provides one line-level audio input and one line-level audio output through terminal connections. A built-in microphone or speaker is not stated, so compatible external equipment is required for audio capture or playback. One alarm input and one alarm output are also available.
The internal slot supports compatible microSD, microSDHC and microSDXC cards up to 512GB. A card is normally sold separately, and recording time depends on bitrate, frame rate, compression and scene activity.
Installation and Compatibility
The lens provides motorised zoom and focus, but the camera body is positioned manually during installation; this is not a PTZ camera. Power can be supplied through a suitable IEEE 802.3at PoE+ source or a correctly rated 12V DC supply connected to the camera's two-core terminal block.
Confirm NVR 6MP decoding, PoE+ budget, human and vehicle event support, external audio and alarm requirements, storage-card compatibility and mounting accessories before ordering. Third-party integration does not guarantee access to every Hikvision analytics function.
Frequently Asked Questions
What is the exact model?
This listing is for the DS-2CD2666G2H-IZS(2.8-12mm) white-finish model. The official G2H datasheet does not add an eF suffix to this hardware version.
What is the maximum resolution?
The maximum resolution is 3200 × 1800, commonly described as 6MP.
What is the maximum frame rate at 6MP?
The camera records at up to 20fps at 3200 × 1800. Higher frame rates are available at supported lower resolutions.
Is the lens motorised?
Yes. Zoom and focus can be adjusted remotely across the 2.8–12mm focal range.
Does it use DarkFighter technology?
Yes. Hikvision identifies this model as Powered-by-DarkFighter.
Is this product officially labelled AcuSense?
The official G2H datasheet describes deep-learning human and vehicle classification but does not use AcuSense in the product title, so this listing does not add that label.
Does it have a built-in microphone or speaker?
No built-in microphone or speaker is stated for this exact model. It provides external audio input and output.
What memory-card capacity is supported?
Compatible microSD-family cards up to 512GB are supported.
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 IP67 and IK10. Correct sealing, mounting and cable protection remain necessary, and no specialist anti-corrosion rating is stated.
