Product SKU: DS-2CD2166G2H-ISU
Product Overview
The Hikvision DS-2CD2166G2H-ISU is a 6MP fixed dome network camera built for high-quality surveillance in residential, commercial, and light industrial settings. It combines detailed imaging, strong low-light performance, smart AcuSense detection, and built-in audio recording in one compact vandal-resistant housing. With reliable day and night monitoring, efficient compression, and weather-resistant construction, it is well suited to sites that need dependable coverage and clearer event verification.
Why Choose the DS-2CD2166G2H-ISU
The DS-2CD2166G2H-ISU is a strong choice for installers and end users who want a balance of image quality, smarter detection, and durability. Its 6MP resolution helps deliver sharper detail than lower-resolution models, while DarkFighter low-light performance improves usability in dim scenes. AcuSense human and vehicle classification helps reduce nuisance alerts, and the built-in microphone adds useful audio context for incident review. Combined with IP67 weather resistance and IK10 vandal protection, it offers practical performance for demanding everyday security applications.
Key Capabilities
6MP Detailed Surveillance
The 6MP image sensor captures sharper and more detailed footage, helping users identify people, vehicles, clothing details, and movement with greater clarity. This makes it especially useful in areas where clearer evidence and better scene coverage are important.
Excellent Low-Light Performance
DarkFighter technology helps the camera maintain better image quality in low-light environments, making it more effective for entrances, shaded walkways, driveways, and perimeter zones that do not always have strong lighting at night.
Smarter AcuSense Detection
AcuSense technology focuses on human and vehicle classification, helping reduce false alarms caused by non-critical movement such as rain, leaves, insects, or general background activity. This gives users more relevant alerts and a more efficient monitoring experience.
Integrated Audio Recording
The built-in microphone allows the camera to capture audio alongside video, which can provide extra context during incident playback. This can be valuable in customer-facing environments, entry points, and areas where voice or sound activity matters.
Rugged Indoor and Outdoor Protection
With IP67 weather resistance and IK10 vandal-resistant construction, the camera is designed to handle exposed outdoor conditions as well as locations where equipment may be at risk of tampering or accidental impact.
Key Features
-
6MP High-Resolution Imaging: The camera records at up to 3200 × 1800 resolution, giving users more detail across the scene. This helps improve subject recognition, supports clearer playback, and makes the camera suitable for sites where stronger visual evidence is important.
-
DarkFighter Low-Light Technology: DarkFighter improves the camera’s performance in dim conditions, helping it produce more usable images where standard cameras may struggle. This is particularly helpful for overnight monitoring, poorly lit side access areas, and shaded outdoor positions.
-
AcuSense Human and Vehicle Classification: Smart classification helps the camera focus on more meaningful events instead of treating every type of motion equally. This reduces unnecessary notifications and makes it easier for users to review events that are more likely to matter.
-
Built-In Microphone: Audio recording adds another layer of context to video footage, which can be useful for reviewing verbal exchanges, environmental sounds, or activity near entrances and counters. It helps create a more complete record of incidents.
-
120 dB Wide Dynamic Range: True WDR helps balance very bright and very dark parts of the same scene. This is useful for locations such as front doors, reception areas, roller doors, and loading zones where backlighting can otherwise reduce image clarity.
-
Efficient H.265+ Compression: H.265+ helps reduce bandwidth and storage usage without sacrificing practical surveillance quality. This can support longer recording retention, lower network load, and better efficiency across multi-camera systems and NVR-based installations.
-
IP67 and IK10 Protection: The housing is designed to resist weather exposure and physical impact, making the camera a dependable option for outdoor areas and vulnerable mounting points. This contributes to longer service life and more reliable operation in demanding environments.

Choosing Between the 2.8mm and 4mm Lens
The DS-2CD2166G2H-ISU offers two fixed lens choices—2.8 mm and 4 mm—so you can select the coverage style that best suits your installation. The 2.8 mm option is typically better for wider scene coverage, while the 4 mm option is better when you want a tighter field of view with more focus on a specific area such as an entry or path.
Tip:
Choose 2.8 mm for wide-area monitoring.
Choose 4 mm for more focused coverage and stronger attention to distant subjects.
FAQs
- Is the DS-2CD2166G2H-ISU suitable for outdoor use?
Yes, this camera is designed for both indoor and outdoor applications. Its IP67 weather-resistant housing helps protect it against dust and water ingress, while its IK10 vandal-resistant rating adds extra durability in exposed or accessible mounting locations. This makes it a practical option for building exteriors, walkways, entry points, and other areas where the camera may be exposed to weather or potential tampering.
- What is the benefit of AcuSense on this camera?
AcuSense helps the camera distinguish between people, vehicles, and less important forms of motion. In practical terms, that means fewer nuisance alerts caused by things like moving branches, animals, or general environmental activity. For users, this creates a more efficient surveillance experience because recorded events and notifications are more relevant and easier to review.
- Why would I want a built-in microphone in a security camera?
A built-in microphone can add important context that video alone may not always provide. In some environments, audio can help confirm what was happening during an incident, capture surrounding sound activity, or provide better understanding of an interaction near the camera. This can be especially useful at entrances, counters, waiting areas, and similar monitored spaces.
