Key Capabilities
Flexible coverage via 2.8–12 mm varifocal lens: The lens range allows installers to adjust focus post-installation, providing adaptability for diverse applications—from wide car park surveillance to closer entry monitoring.
Full-colour imaging in low light: ColourVu technology, paired with a large-aperture lens and smart lighting, ensures vivid colour capture even under very low illumination, enhancing identification and visual clarity.
Smart Hybrid Illumination (IR + white light): Automatically switches lighting modes up to 60 m, combining IR for covert surveillance and white light for clear colour when events are triggered—improving detection and deterrence.
AI-powered human & vehicle classification: Built-in AcuSense analytics enable the camera to distinguish between human and vehicle targets and filter irrelevant motion, reducing false alarms and enhancing response accuracy.
Active deterrence capability: Integrated strobe light and audio alarm provide immediate visual and audible warnings when a security event is detected, helping to thwart intrusion attempts in real time.
Rugged outdoor build: IP67 weather-proof and IK10 vandal-resistant housing (plus optional anti-corrosion “-Y” design) ensures reliability in harsh outdoor environments and coastal installations.
