Hikvision 5MP AcuSense
Turret Network Camera
DS-2CD3356G2-IS(U) — Built-in Mic · H.265+ · 120dB WDR · Deep Learning AI
Why Choose the DS-2CD3356G2-ISU
Professional-grade AcuSense AI camera delivering pin-sharp 5MP footage around the clock.
Powered-by-DarkFighter Technology
Hikvision's DarkFighter sensor pushes sensitivity to extraordinary limits, capturing vivid, full-colour footage in near-total darkness where conventional cameras would only deliver grainy greyscale images.
- Colour imaging down to 0.003 lux (F1.6)
- Monochrome performance down to 0 lux with IR on
- Built-in IR up to 30 m — no external lighting needed
5 Megapixel High-Resolution Video
At 5 MP (2560 × 1944), this camera delivers over twice the detail of standard 1080p HD cameras — capturing faces, licence plates, and incidents with the clarity needed for investigation and evidential use.
- Max resolution 2560 × 1944 @ 20fps
- 120 dB true Wide Dynamic Range (WDR)
- 3D DNR digital noise reduction for clean low-light footage
Built-in Microphone for Audio Recording
The integrated microphone captures ambient audio alongside video, providing a complete picture of events with no need for a separate audio input cable or external mic. Essential for retail, reception, and office environments.
- Onboard digital microphone — no extra hardware needed
- Audio stream synced with video recording
- Supports audio detection alarm triggering
Deep Learning — Human & Vehicle Detection
AcuSense AI classifies moving objects as human or vehicle in real-time, filtering out animals, moving foliage, and other false triggers. You get meaningful alerts only when it truly matters.
- Perimeter intrusion & line-crossing detection
- Dramatically reduced false alarm rate vs. motion-only cameras
- Instant push notifications to Hik-Connect app
H.265+ Smart Compression Technology
H.265+ uses intelligent scene analysis to reduce bitrate by up to 75% compared to H.264, slashing storage costs and bandwidth use without compromising image quality. More days of recording for less.
- Up to 75% storage saving vs. H.264
- Advanced streaming for smooth live-view over poor networks
- Data self-correction reduces video loss on unstable connections
IP67 Water & Dust Resistant
Fully sealed against dust ingress and capable of withstanding water jets from any direction, the IP67 rating makes this camera equally at home in a UK car park in November as in a dry indoor space.
- Total protection against dust and foreign particles
- Protected against sustained high-pressure water jets
- Operating temperature −30 °C to 60 °C
Versatile Applications
Designed to perform in any environment — indoors or outdoors.
