Hikvision G2 vs G3 Models: What’s the Difference?

When it comes to choosing the right CCTV solution, Hikvision remains one of the top choices in the UK for both domestic and commercial security setups. But as the brand continues to innovate, many users are now asking: what’s the actual difference between the G2 and G3 camera models?

If you're upgrading your system or installing a new one, understanding the leap from G2 to G3 can help you make an informed decision.

1. Hardware Upgrades

Processing Power

One of the most significant changes in the G3 series is the upgraded chipset. G3 models generally feature more powerful processors compared to G2, enabling better image processing, faster analytics, and more reliable performance in challenging conditions.

Improved Low-Light Performance

G3 cameras often come equipped with improved DarkFighter or ColorVu technology, giving clearer images at night or in low-light environments, which is a clear upgrade over many G2 models.

2. AI & Analytics Features

Enhanced AcuSense Technology

While both G2 and G3 may include AcuSense, the G3 models take it a step further:

• G3 cameras feature Gen 2 or Gen 3 AcuSense, offering more accurate human and vehicle detection.

• Improved false alarm filtering, which helps reduce unnecessary alerts caused by animals, leaves, or lighting changes.

Object Classification

G3 cameras can classify a wider range of objects more accurately, making them more suitable for smart monitoring solutions, especially in commercial or high-traffic areas.

3. Compatibility and Integration

Firmware and Software Support

G3 models are built with future firmware updates and compatibility in mind. They're more likely to support upcoming features in the Hik-Connect ecosystem and integrations with third-party systems.

ONVIF and Platform Support

Both G2 and G3 models are ONVIF-compliant, but G3 models are typically tested for wider integration and may include support for the latest ONVIF profiles.

4. Design & Build

Refined Design

G3 models often have subtle refinements in their casing, better heat dissipation, and are slightly more compact, making them more versatile for discreet installations.

Durability

Improvements in waterproofing (IP ratings) and vandal-resistant housings (IK ratings) are more prevalent in G3 devices, especially for outdoor use.

5. Pricing and Availability

As expected, G3 models tend to be slightly more expensive, reflecting the newer hardware and software capabilities. However, the price difference is often justified by the boost in performance and longevity.

Should You Upgrade to G3?

If you're currently using G2 models and they’re meeting your needs, there’s no immediate urgency to upgrade. However, if you're looking for:

• Better AI analytics,

• More reliable night vision,

• Future-proofing with newer firmware support,

Then G3 models are a smart choice, especially for business premises or high-security areas.

Final Thoughts

The leap from G2 to G3 in Hikvision’s lineup isn’t revolutionary, but it is evolutionary. With improved AI, better image processing, and more durable designs, G3 models offer tangible benefits – especially for users looking to get more out of their security system.
