Compliance and Compatibility

• ONVIF & Standards: Supports ONVIF Profile S/G/T (plus Hikvision’s SDK/ISAPI) for seamless integration with most NVRs and VMS.
• NDAA-Compliant: Contains no banned US-sourced components, making it approved for government and public sector use.
• Regulatory: CE and UKCA marked; RoHS-certified (lead-free). It satisfies the FCC/UL requirements for safety in the EU/UK.
• Security: HTTPS, SSH, TLS 1.1/1.2/1.3 support; 802.1X authentication (EAP-TLS, MD5, etc.); advanced password/DH encryption.

Frequently Asked Questions:

1) What are the headline features of the Hikvision DS-2CD2347G3-LI2UY?

Quick answer: 4MP ColorVu 3.0 (24/7 colour), Smart Hybrid Light (white + IR), AcuSense AI for person/vehicle classification, built-in arrayed dual-microphone, PoE, IP67 + NEMA4X anti-corrosion and ONVIF compatibility.

2) Will this camera give me colour images at night?

Yes — ColorVu 3.0 plus an F1.0 super-aperture lens produces bright, full-colour images in very low light; when needed, the camera uses the white supplement light for vivid colour at night (0 Lux with light). Great for ID and evidence capture.

3) What resolution, lens and field of view does it have?

The camera records at 4MP (2688×1520). The 2.8 mm lens version gives a ~111.1° horizontal FOV (the 4 mm version is narrower). Choose 2.8 mm for wide coverage (driveways, small car parks).

4) Does AcuSense really cut down false alarms?

Yes — this model uses deep-learning AcuSense to classify human vs vehicle targets (so alerts can ignore most other motion). It’s designed to reduce nuisance notifications while keeping meaningful alerts. (As with all AI, tune sensitivity and ROI for best results.)

5) Is it PoE and how much power does it use?

Yes — PoE (IEEE 802.3af, Class 3). Power draw is listed as max ~11 W via PoE (or 12 VDC, max ~8.5 W via DC). PoE makes installation neater — a single cable for power + data.

6) Can I record to a microSD card and how big can the card be?

Yes — it has an on-board microSD slot and supports microSD/microSDHC/microSDXC up to 512 GB for local storage (also supports NAS/ANR).

7) Is it weatherproof and suitable for UK coastal sites?

Yes — IP67 rated for dust/water and NEMA 4X anti-corrosion design. Hikvision classifies this model with moderate anti-corrosion protection (suitable for coastal areas at a reasonable distance and typical UK weather). For extreme coastal/industrial use check the mounting location and maintenance schedule.

8) Does it support two-way audio (talkback)?

Short: the camera has built-in arrayed dual microphones for high-quality audio capture, but it does not include a built-in speaker for full two-way talk on the standard LI2UY variant. If you need talkback, you can integrate an external Smart PA speaker or choose the specific model/variant that explicitly lists two-way audio. (Check product variant notes when ordering.)

9) Will it work with my existing NVR / VMS or Hik-Connect?

Yes — it supports ONVIF Profile S/G/T plus Hikvision ISAPI/SDK, and it’s compatible with Hik-Connect / HikCentral / iVMS-4200. That makes it easy to add to third-party NVRs or Hikvision management platforms.

10) Is this model NDAA-compliant, and what warranty does it have?

NDAA: The official Hikvision datasheet does not declare NDAA compliance, and reseller listings vary — several UK resellers list NDAA as No. If NDAA compliance is mandatory (e.g., a government contract), confirm with your vendor or choose a model specifically certified for that program.
Warranty: When purchased through an authorised Hikvision partner, like CCTVTEK, the product comes with a 3-year warranty. We also provide ongoing technical support to assist you throughout the warranty period and beyond.
