Hikvision model numbers look cryptic, but they follow a logical pattern. Once you know the basics you can read a model like DS-2CD2366G2H-ISU at a glance — its type, resolution, generation and features. Here is the plain-English decoder, with genuine Hikvision stock from an authorised Hikvision reseller.
Start with the prefix — what type of device is it?
| Starts with | What it is |
|---|---|
| DS-2CD… | Network (IP) camera |
| DS-2CE… | Turbo HD (analog) camera |
| iDS-2CD8… | DeepinView AI camera |
| DS-7…NXI | Network Video Recorder (NVR) |
| iDS-7…HUHI | Turbo HD DVR |
The number tells you the resolution
Within the model number there is a digit that reflects the megapixels. As a general rule a 6 means 6MP, an 8 means 8MP and a 4 means 4MP. So a DS-2CD286 is an 8MP camera and a DS-2CD266 is 6MP. (Our product titles always state the resolution outright.)
Generation and technology
G2 means Generation 2, and a trailing H typically marks a hybrid model with AcuSense and improved imaging. You will also see the technology spelled out — AcuSense for smart person/vehicle detection and ColorVu for full-colour night vision.
The suffix letters are the features
| Letter / code | Meaning |
|---|---|
| I | Infrared night vision |
| U | Built-in audio (microphone) |
| S | Alarm input/output |
| /SL | Strobe light (active deterrence) |
| 2.8mm / 4mm | Lens focal length (field of view) |
Worked example
DS-2CD2366G2H-ISU (2.8mm) reads as: an IP camera (DS-2CD), 6MP (the 6), Generation 2 hybrid with AcuSense (G2H), featuring infrared (I), alarm I/O (S) and built-in audio (U), with a 2.8mm wide lens. Easy once you know the pattern.
