Hikvision DS-2CD2147G3-LIY — 4MP ColorVu Smart Hybrid Light Dome
4 MP · 2.8 mmColorVu F1.0Hybrid light 30 mPoE · IP67 · IK10
The Hikvision DS-2CD2147G3-LIY is a 4 MP ColorVu fixed dome network camera with a 2.8 mm F1.0 lens and Smart Hybrid Light (white light plus IR) reaching up to 30 m, so it can record in colour at night or switch to infrared when you do not want visible light. It suits shops, offices, entrances and car parks that need wide coverage from a vandal-resistant dome.
Deep-learning human and vehicle classification cuts false alarms from animals, leaves and headlights, and perimeter rules (line crossing, intrusion, region entry/exit) let you alert only on what matters.
Before you order: This LIY model has no built-in microphone, no audio in/out and no alarm I/O. If you need audio or an alarm contact, ask us for the LIS2UY version.
What's in the Box
- 1× Hikvision DS-2CD2147G3-LIY (2.8 mm) dome camera
- Mounting brackets/junction box, PSU and microSD card are not included
What It Means in Practice
- Power it from an 802.3af PoE switch or injector (max 9 W), or from a 12 V DC adapter — neither is included.
- The 2.8 mm lens gives a wide 111° horizontal view: great for rooms and entrances, but less detail on faces or plates far from the camera (a 4 mm version exists for that).
- Local recording on a microSD card up to 512 GB, or to an NVR.
- Colour at night needs the white light on; switch the smart light to IR mode where white light would disturb neighbours.
What Will Not Work
- Wi-Fi — it is a wired Ethernet camera only.
- Audio recording or two-way talk (no microphone or audio ports on LIY).
- Alarm inputs/outputs.
- Operation without a PoE switch/injector or a 12 V adapter.

Frequently Asked Questions
Can it record in colour at night?
Yes — with the white light active and the F1.0 ColorVu optics. You can switch to IR-only mode for black-and-white night video without visible light.
Does it need an NVR?
No. It can record to a microSD card (up to 512 GB) and be viewed in the Hik-Connect app, but an NVR is better for multi-camera sites and longer retention.
2.8 mm or 4 mm?
2.8 mm covers a wider area (about 111°); 4 mm sees less width but more detail at distance, better for gates and long corridors.
Singular Expert Insight · Buyer's Guide
For small business sites the 4 MP ColorVu dome is a sweet spot: colour evidence at night, AI filtering that keeps alerts useful, and simple PoE installation. Plan a PoE switch with enough budget for all cameras and see our other
IP cameras for bullet and turret options.
✓ Buy it if you want a wide-angle, vandal-resistant dome with colour night vision and smart human/vehicle alerts.
✕ Skip it if you need audio, alarm I/O, Wi-Fi or a narrow view of distant details.
→ Also consider the LIS2UY version for audio and alarm I/O, or a 4 mm lens for longer distances.
