Hikvision G2 vs G3 Cameras: What Changed?

What does the G2 or G3 in a Hikvision model number mean?

Hikvision builds its network cameras on rolling hardware platforms, and the G-number in the model code tells you which generation a camera belongs to. A G2 camera sits on the second-generation platform; a G3 camera sits on the newer third-generation platform. It is a versioning marker, much like a software release number: a higher number means a more recently designed board, processor and feature set.

Take two real turrets we stock: the DS-2CD2386G2H and the DS-2CD2387G3. Same 8MP class, same brand, same turret shape, but the G2 and G3 tell you they were engineered in different generations. Neither is "fake" or lesser, they are simply different points on Hikvision's roadmap. If you want the full breakdown of every letter and digit, our guide to reading Hikvision model numbers decodes the whole string.

Where to find the generation code in the model number

The generation code sits in the middle of the model string, right after the resolution digits and before the feature suffixes. Read it left to right:

So DS-2CD2386G2H reads as an 8MP fixed camera on the G2 platform, and DS-2CD2387G3 as an 8MP fixed camera on the G3 platform. The letters after the generation code describe the actual features (colour night vision, microphone, active deterrence), which is where a lot of the real-world difference shows up. For the full letter-by-letter decode, see our model-number guide.

What usually improves from one generation to the next

Hikvision does not publish a single fixed spec jump between generations, and the exact changes vary model to model, so treat the following as general trends rather than guaranteed numbers. Broadly, a newer generation tends to bring:

• A newer chipset — updated image processing and, on many models, more efficient encoding.
• Refreshed low-light imaging — newer ColorVu optics and sensors aimed at cleaner full-colour night video, often with an updated warm supplement light.
• Updated AcuSense analytics — the on-camera human and vehicle detection that powers smarter alerts keeps being tuned; see AcuSense explained.
• Feature consolidation — capabilities such as microphones, active strobe-and-audio deterrence and hybrid lighting appear more often as standard on newer suffixes.

G2 vs G3: a general comparison

Here is how the two generations compare at a high level. Because Hikvision spans dozens of models per generation, the table describes typical positioning rather than the spec of any one camera.

Not sure whether you actually need colour night vision or AI detection first? Our ColorVu vs AcuSense comparison explains which technology matters for your situation, and ColorVu vs DarkFighter covers the two low-light approaches you will see across both generations.

Is G3 worth choosing over G2?

For a brand-new installation where you want the most current platform and the longest runway before it is superseded, the newer G3 generation is a sensible default. You get the latest chipset and the most recent ColorVu and AcuSense tuning, which is exactly what you want if the site will run for years.

G2 still makes great sense when you are matching cameras to an existing G2 fleet, replacing a failed unit, or simply want proven, heavily stocked hardware at strong value. A G2 ColorVu or AcuSense camera is far from old, it is a capable, current-support product. The honest answer is that the generation is one input, not the deciding factor: lens choice, resolution, ColorVu vs infrared, and the mounting form usually matter more to real footage quality than G2 versus G3 alone.

How to choose the right generation for your site

Work through it in this order and the generation question tends to answer itself:

• Match existing kit? If you are expanding a G2 system, another G2 keeps things consistent. Starting fresh? Lean G3.
• Pick the features you need — colour night vision, a microphone, active deterrence — then read the suffix, not just the G-code.
• Choose the form factor — turret, bullet, dome or turret — for where each camera mounts.
• Confirm resolution and lens for the distance you need to cover.
• Check stock and support — buying genuine from an authorised Australian reseller means local warranty and Melbourne dispatch.
