Detailed specifications and benefits
Understanding the cameras technical specifications helps highlight where it provides real operational value. Below is a closer look at the DS-2CD2386G2-IUs key subsystems and the benefits they bring.
- 1/1.8" progressive scan CMOS sensor delivering 3840 D7 2160 (8 MP) resolution. Benefit: the high pixel count yields clearer evidence for identification and wider coverage per camera, which can reduce the total number of cameras required for a site.
- 2.8 mm fixed lens (F1.6) with an approximate horizontal field of view of 111. Benefit: a wide field of view well suited to monitoring lobbies, retail floors and short‑to‑mid range outdoor areas without distortion typical of ultra‑wide lenses.
- DarkFighter technology enables colour imaging down to 0.003 lux and monochrome with IR to 0 lux. Smart IR (850 nm) extends usable night range to around 30 m. Benefit: retains useful visual detail in very low ambient light, reducing reliance on additional scene lighting and improving identification at night.
- AcuSense deep‑learning algorithms perform human/vehicle classification and offer face detection. Benefit: fewer nuisance alerts from animals, foliage, shadows or other non‑relevant motion—saving operator time and storage by focusing on meaningful events.
- Supports modern codecs H.265/H.265+ and H.264/H.264+, with CBR/VBR and ROI options. Multiple streams (main/sub/third) support remote viewing, recording and mobile apps simultaneously. Benefit: efficient bandwidth and storage utilization without compromising image quality when needed.
- On‑board microSD support up to 256 GB, plus NAS (NFS/SMB/CIFS) and ANR capability. Benefit: flexible edge or centralized recording options and redundancy against temporary network loss.
- Built‑in microphone ("-U" variant) with common audio codecs. Benefit: captures ambient audio cues to supplement video evidence—useful in retail incidents, alarm verification, or certain access control events. Ensure compliance with local audio recording regulations.
- Network: RJ45 10/100 Mbps with ONVIF Profile S/G/T support. Benefit: interoperability with many third‑party recorders and VMS platforms.
- PoE (802.3af) or 12 VDC operation; low power consumption (typical ~6.8 W PoE). IP67 weather rating and robust turret design. Benefit: straightforward installation with PoE switches or midspan injectors, and durability in outdoor or exposed indoor sites.
Use cases and scenarios where this camera excels
The DS-2CD2386G2-IUs combination of 4K resolution, DarkFighter low‑light capabilities and AcuSense analytics makes it well suited to a range of applications:
- Retail stores and shopping centres:wide, high‑resolution coverage for aisles and entrances helps with loss prevention, customer flow analysis, and incident forensics. AcuSense reduces false alarms from routine motion while the built‑in microphone provides contextual audio for disputes or alarms.
- Commercial buildings and lobbies:the cameras 4K sensor captures facial detail and wide areas in a single unit, and DarkFighter preserves colour in dim conditions common in reception areas and after‑hours.
- Perimeter and car parks:the wide 2.8 mm view and IR to ~30 m allow monitoring of immediate approach zones and vehicle movement. AcuSense helps distinguish people from vehicles for targeted alerting.
- Small campuses and multi‑site rollouts:PoE simplifies wiring and centralized management via ONVIF‑compatible recorders or Hikvisions own platforms supports efficient deployments across multiple locations.
How it compares with similar products on the market
The DS-2CD2386G2-IU competes in the class of 4K turret IP cameras. Key differentiators and comparable tradeoffs include:
- Low‑light performance:Hikvisions DarkFighter is a strong point against many competitors in this price band. Cameras without equivalent low‑light optimization may produce noisier or monochrome images at low lux levels.
- Intelligent analytics:AcuSenses human/vehicle classification provides a tangible operational advantage versus basic motion detection. Some rival vendors offer similar deep‑learning analytics, so consider the specific VMS and analytics ecosystem when choosing a brand.
- Audio integration:Built‑in microphones are not universal across competitors; when audio context is important, the "-U" variant simplifies installation versus adding a separate microphone.
- Value and lifecycle:The suggested retail price positions this camera as a competitive option for 4K turret cameras. However, this model is listed as discontinued by Hikvision—buyers should verify warranty, firmware update availability and long‑term support compared with current models from Hikvision and rivals.
Customer impressions and typical feedback
There are no proprietary customer testimonials included with the product data provided here. Based on common feedback patterns for cameras with similar feature sets, prospective buyers frequently note the following points:
- Positive: Users praise DarkFighter for maintaining colour detail in low light, and appreciate AcuSense for significantly reducing false alarms in busy environments.
- Positive: Built‑in audio is valued for giving additional context during incidents without extra hardware complexity.
- Constructive: Some integrators remark that discontinued models require extra diligence—confirming firmware updates and spare part availability with suppliers is important.
- Constructive: As with many 4K cameras, achieving full benefit depends on correct lens choice, network bandwidth and storage planning; installers often recommend testing streams and retention before full rollout.
Final considerations and conclusion
The Hikvision DS-2CD2386G2-IU (2.8 mm) offers a compelling blend of 4K resolution, DarkFighter low‑light imaging, AcuSense analytics and an integrated microphone in a weatherproof turret form factor. For sites that require high detail, reliable night performance and smarter alarm filtering—such as retail environments, commercial lobbies and near‑perimeter zones—this camera provides many of the features demanded by modern surveillance systems.
However, this model is listed as discontinued by the manufacturer. That does not mean the hardware is inherently unsuitable; rather, it underscores the need to verify warranty terms, firmware update availability and long‑term support with your supplier before purchase. If ongoing vendor support is critical for your project, compare current models in Hikvisions lineup or equivalent offerings from other vendors that provide similar DarkFighter‑level low‑light and deep‑learning analytics.
In summary, where availability and support are confirmed, the DS-2CD2386G2-IU remains a strong choice for deployments that prioritise high resolution, low‑light colour fidelity and reduced nuisance alarms. Pair it with a qualified installer, a well‑planned network and an appropriate recording strategy to maximise its performance in real world settings.
