FAQ
What is AcuSense technology?
AcuSense is Hikvision’s intelligent video analytics technology powered by deep learning algorithms. It enables the camera to accurately distinguish between humans, vehicles, and other objects, significantly reducing false alarms caused by animals, weather conditions, or moving vegetation.
What does DarkFighter technology do?
DarkFighter technology enhances the camera’s performance in extremely low-light conditions. It allows the camera to capture clear, detailed images even when ambient lighting is minimal, with illumination requirements as low as 0.001 Lux in colour mode.
Is the camera suitable for outdoor installation?
Yes, the camera has an IP67 rating, making it fully protected against water and dust ingress. It can operate in temperatures from -30°C to 60°C and is suitable for all-weather outdoor installations.
What power options are available?
The camera supports both 12V DC power supply and Power over Ethernet (PoE) IEEE 802.3af. PoE is often preferred as it allows both power and data transmission through a single network cable.
Can I record audio with this camera?
Yes, the IU model includes a built-in microphone that enables real-time audio recording alongside video surveillance, providing additional security intelligence.
What storage options are available?
The camera includes a built-in microSD card slot supporting cards up to 512GB. It also supports network storage options including NAS, FTP, and cloud storage through compatible Hikvision recorders and software.
