Hikvision DS-2CD1T47G2H-LIUF/SRB(4mm) – 4 MP ColorVu with Smart Hybrid Light Fixed Bullet Network Camera with Red & Blue Strobe Light Alarm
The Hikvision DS-2CD1T47G2H-LIUF/SRB(4mm) is a 4 MP ColorVu fixed bullet network camera built for outdoor sites that need visible, unmistakable deterrence alongside full-colour night footage. Specifically, it uses a 1/3″ progressive scan CMOS sensor with an F1.0 large aperture paired with a fixed 4 mm lens, giving an 80° horizontal field of view and a detection range up to 77 m. In addition, its Smart Hybrid Light system combines infrared and white-light illumination up to 50 m; as a result, footage stays in full colour around the clock instead of switching to grainy black-and-white at night.
Meanwhile, onboard person and vehicle detection classifies motion events instead of triggering on every moving object, which in turn cuts down on false alerts from leaves, shadows, or small animals. Furthermore, built-in two-way audio and a red-and-blue strobe light mimic the visual signature of emergency vehicles, so intruders get a stronger deterrent than a plain white flash. On top of that, the housing carries an IP67 rating for dust and water resistance, and an on-board microSD slot supports up to 512 GB of local storage, so the camera can still capture footage if the network connection drops.

Who This Camera Suits Best
- High-risk entrances and gated compounds – the red-and-blue strobe gives a stronger visual warning than a plain flash, suited to sites that have seen repeat break-in attempts.
- Businesses wanting active deterrence with evidence-grade footage – for instance, security staff can issue live voice warnings through the two-way audio while ColorVu captures faces and vehicle colour clearly.
- Standalone sites without an NVR – since on-board storage reaches up to 512 GB, it can record independently at gates, compounds, or outbuildings where running a full recorder isn’t practical.
