1x Hikvision 4MP 2.8mm AcuSense Darkfighter Turret Network IP Camera Built in Mic DS-2CD2346G2-IU/GREY

Frequently Asked Questions

1. What resolution and lens does this camera use?
   It’s a 4-megapixel camera (max 2688 × 1520 at 30 fps) with a fixed 2.8 mm lens (≈103° horizontal FOV) — good for general-purpose coverage where you want a wide field without a motorised zoom.

2. What is “DarkFighter” and does this model really work well at night?
   DarkFighter is Hikvision’s low-light imaging tech — it boosts sensitivity so you get color or usable B/W images in very low light before IR kicks in. This model pairs DarkFighter with IR up to ~30 m for reliable night performance.

3. What does “AcuSense” do — will it cut down false alarms?
   AcuSense uses deep-learning classification to focus alarms on people and vehicles (and ignore many moving trees/animals), significantly reducing false positives in motion alerts. It’s not perfect, but it’s a major filter compared with plain motion detection.

4. Does it have a microphone / can it do two-way audio?
   The “-U” variants include a built-in microphone for one-way audio capture (useful for recording sound). There is no built-in speaker on the standard DS-2CD2346G2-IU, so two-way talk requires a separate speaker or an NVR with external audio out.

5. How do I power it — PoE or mains?
   You can power it via PoE (IEEE 802.3af) or 12 V DC — PoE is the simplest for network installs because power and data use the same cable.

6. Can I store footage on the camera itself? How much?
   Yes — it has a built-in microSD slot. The official datasheet lists support for up to 512 GB (use a high-endurance card rated for surveillance).

7. What weather rating/model differences should I watch out for?
   There are variant codes: the DS-2CD2346G2-I and DS-2CD2346G2-IU differ slightly in ingress specs depending on the market—check the exact suffix, but commonly the unit is rated IP66/IP67 depending on the model/region (confirm on the label and datasheet before outdoor installs). In short: pick the variant marked for outdoor/waterproof use.

8. What compression, streaming and bitrate options does it support?
   It supports H.265/H.265+ and H.264/H.264+ (plus MJPEG on substreams), with bitrate control (CBR/VBR) and ROI — this helps reduce storage and bandwidth while keeping important areas sharp.

9. Will it work with my NVR, Hik-Connect or other systems (ONVIF)?
   Yes — it’s compatible with Hikvision’s ecosystem (Hik-Connect/HikCentral) and supports ONVIF profiles (S/G/T) and standard network protocols so you can integrate it with many third-party NVRs that support those profiles. Still — verify compatibility with your NVR model and firmware.

10. Common installation/troubleshooting tips people search for:

    Use PoE from a managed switch or PoE injector to avoid power headaches. Format and install a high-endurance microSD card before relying on local storage. Update the camera firmware from Hikvision’s official downloads and change default passwords. If you see lots of “motion” alerts despite AcuSense, check sensitivity and detection zones, and ensure firmware is current—most false-alert tuning is done in the camera/NVR settings. (These are the usual fixes installers mention.)

11. What warranty and support are included?
    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.
