Hikvision DS-2CD2147G3-LIS2UY(2.8MM) – 4 MP Smart Hybrid Light with ColorVu Fixed Dome Network Camera
The Hikvision DS-2CD2147G3-LIS2UY(2.8mm) is a Pro-series 4 MP fixed dome network camera built around ColorVu imaging and an F1.0 super-aperture lens. Specifically, it uses a 1/1.8″ progressive scan CMOS sensor with HikAI-ISP noise reduction, which keeps colour visible down to just 0.0001 Lux. As a result, footage stays vivid around the clock, instead of fading to grainy monochrome at night. In addition, Smart Hybrid Light blends IR and white-light illumination across three supplemental modes, extending clear coverage up to 30 m.
Meanwhile, deep-learning-based person and vehicle classification drives smarter alerts, and perimeter tools such as line crossing, intrusion detection, and region entrance/exit add another layer of protection. Furthermore, the -S2U designation means this variant includes a built-in arrayed dual-microphone for high-quality audio pickup, plus an alarm input/output for linking to sirens or access control. On top of that, the housing carries an IP67 rating for dust and water resistance, an IK10 vandal-resistant rating, and NEMA 4X-level anti-corrosion protection, making it noticeably tougher than standard value-series domes.
Unlike the value-series LIU models, this camera does include on-board storage: a built-in microSD slot supports cards up to 512 GB, alongside a functioning reset key. Therefore, it can record independently or work alongside an NVR, and it also supports NAS recording over NFS or SMB/CIFS for larger deployments.

Who This Camera Suits Best
- Retail shops, offices, and reception areas needing audio evidence – for instance, the built-in dual microphone captures clear audio alongside 24/7 colour footage at entrances and tills.
- Coastal or corrosion-prone sites in Kenya – since the housing carries NEMA 4X-level anti-corrosion protection, it suits installations near the coast or in humid, salty environments better than standard domes.
- Perimeter security for compounds and warehouses – deep-learning line crossing and intrusion detection, meanwhile combined with IK10 vandal resistance, suit boundary walls, loading yards, and unattended sites prone to tampering.
