Hikvision 16MP Network Cameras: Four Times the Detail of 4MP for Small Businesses
Hikvision has launched its first 16MP network cameras for small and medium-sized businesses, the 2x166G3 series, giving shops, car parks and offices four times the pixels of a typical 4MP camera. Announced on 30 October 2025, the range brings a level of detail that used to be reserved for large enterprise systems. Here's what 16MP really means, the technology inside, and where it makes a difference.
What is the Hikvision 2x166G3 series?
The 2x166G3 cameras record at up to 4608 × 3456 pixels. That's about 16 million pixels per frame, against roughly 4 million on a 4MP camera and 8 million on 4K (8MP). Hikvision offers the series in standard and Live Guard versions, the latter adding active deterrence such as a strobe light and siren.
Hikvision lists these key technologies:
- 16MP ultra-high definition for capturing fine detail across a wide scene, which speeds up investigations after an incident.
- DarkFighter low-light imaging, which improves light intake and uses deep learning to keep the picture bright and clear in dim conditions. That matters because very high-resolution sensors usually struggle in low light.
- Enhanced WDR (wide dynamic range), which switches on automatically to balance bright and dark areas in the same frame, such as a shop doorway on a sunny day.
- NEMA 4X protection, a rating that includes corrosion resistance, plus a tamper-resistant design.
Why would you want 16MP?
More pixels means you can zoom into recorded footage and still read detail. A single 16MP camera covering a wide area can show a face at the far side of the shop floor, or a number plate across the car park, where a 4MP camera would only show a blur. In practice it means:
- Fewer cameras for the same coverage. One wide 16MP view can sometimes replace two lower-resolution cameras.
- Better evidence. More detail gives the police and insurers footage they can actually use.
- Future-proofing. A higher-resolution camera stays useful for longer.
Where 16MP cameras help
- Retail and commercial spaces. Sharp footage of displays, tills and entrances helps with loss prevention and merchandising.
- Car parks and yards. Hikvision says the cameras can capture space occupancy and number plate detail from a distance.
- Warehouses and loading bays, where a wide view needs to cover a lot of ground.
- Offices and receptions that want clear face detail at the door.
Things to plan for
16MP footage carries more data, so check the rest of the system can keep up:
- Recorder: make sure your NVR accepts 16MP cameras (check its maximum input resolution) and has enough incoming bandwidth. See our Hikvision NVR range.
- Storage: higher resolution means larger recordings. Size your drives with our CCTV storage calculator and use surveillance-rated hard drives.
- Network: a Gigabit PoE switch is sensible when several high-resolution cameras share one switch.
16MP Hikvision cameras we stock
- DS-2CD23166G3-I2UY 16MP AcuSense turret (white) and the black version.
- DS-2CD23166G3-IS2UY/SL 16MP turret with strobe and siren (white) and the black version, for active deterrence.
All four include AcuSense, Hikvision's AI that tells people and vehicles apart from other movement to cut false alarms.
Our take
For years, 4MP has been the sensible default for small business CCTV, with 8MP (4K) for wider areas. A 16MP turret at a mainstream price changes that sum, especially for wide spaces where you'd otherwise fit extra cameras. Just remember to budget for the recorder and storage that go with it.

Quick questions
What resolution is 16MP?
The 2x166G3 series records at up to 4608 × 3456, about four times the pixels of a 4MP camera.
Will a 16MP camera work on my existing NVR?
Only if the recorder supports 16MP cameras and has enough incoming bandwidth. Check the NVR datasheet, or ask us.
Is 16MP good at night?
Hikvision uses DarkFighter low-light technology on this series to keep the picture clear in dim light, which is usually a weakness of very high-resolution sensors.
What is Live Guard?
Hikvision's name for cameras with active deterrence, such as a flashing strobe light and audible warning, to put intruders off before anything happens.
