1x Hikvision 8MP 2.8mm AcuSense Darkfighter Turret Network IP Camera Built-in Mic DS-2CD2386G2H-IU/GREY

Frequently Asked Questions:

• What exactly is the Hikvision DS-2CD2386G2H-IU (GREY, 2.8 mm)?
  A robust 8-megapixel (4K) turret IP camera with a 2.8 mm wide-angle lens, powered-by-DarkFighter low-light sensor, on-device AcuSense analytics and a built-in microphone (the “-IU” suffix). The grey metal housing is weatherproof for outdoor use.

• What field of view do I get with the 2.8 mm lens?
  The 2.8 mm fixed lens delivers a wide field of view — roughly 108.8° horizontal — making it great for entrances, shopfronts, driveways and other broad scenes.

• How good is its night vision / low-light performance?
  Excellent for its class: the DarkFighter sensor captures usable colour images in very low light (specs list colour sensitivity down to 0.0008 Lux) and the camera also has IR illumination for true 0-Lux B/W when needed (IR range ~30 m). In short — much better night detail than ordinary dome cameras.

• What does AcuSense do and will it reduce false alarms?
  AcuSense uses on-device deep learning to prioritise human and vehicle events and ignore most nuisance triggers (pets, leaves, rain). It significantly cuts false positives when you configure detection zones sensibly. It’s not perfect, but it’s a big practical improvement over plain motion detection.

• Does the “-IU” model record audio and is two-way talk supported?
  Yes — the “-IU” includes a built-in microphone for one-way ambient audio capture alongside video. Two-way intercom depends on the specific variant/recorder setup; check your NVR/VMS for two-way support.

• How do I power the camera — PoE or mains?
  You can use Power over Ethernet (IEEE 802.3af) for a tidy single-cable install or a 12 V DC adapter where PoE isn’t available. PoE is usually the easiest choice for outdoor installations.

• Can I record locally (microSD) and how much space does it support?
  Yes — the camera has a microSD slot for edge recording. Official listings typically state support up to 512 GB, which is handy as a backup if network recording temporarily fails. For long retention, use a network video recorder (NVR) too.

• Is this camera suitable for UK outdoor use (weather, temperature)?
  Yes — the grey metal turret is IP67 rated for dust and water resistance and is specified for wide operating temperatures, so it’s built to handle British weather when mounted correctly. Proper cable sealing and a good mounting position still matter.

• Will it work with third-party NVRs/VMS (ONVIF/compatibility)?
  Generally yes — the camera supports standard network video protocols and H.265+/H.264+ compression and is commonly supported by mainstream NVRs/VMS packages. Always test compatibility (or check the recorder’s compatibility list) before a large rollout.

• Is it legal to use a camera with audio in the UK — any GDPR concerns?
  Recording audio is lawful but more intrusive than video alone. The ICO advises you to consider whether audio is necessary, use clear signage, keep a lawful basis for processing and limit retention. For business installs, you should document purpose, security and retention policies to meet UK GDPR/DPA rules. If in doubt, follow ICO guidance or seek legal advice.

• 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.
