FAQ
What is AcuSense technology and how does it work?
AcuSense is Hikvision’s deep learning-based technology that uses advanced algorithms to accurately distinguish between humans and vehicles. This significantly reduces false alarms caused by animals, weather conditions, or moving objects, ensuring security teams only respond to genuine threats.
How does the strobe light deterrent function work?
The camera features a built-in white strobe light that can be triggered automatically when motion is detected or manually activated. Combined with the audible alarm, this active deterrent system warns potential intruders and can help prevent incidents before they occur.
What storage options are available with this camera?
The camera supports multiple storage options including on-board microSD card storage up to 512 GB, network-attached storage (NAS) via SMB/CIFS or NFS protocols, and automatic network replenishment (ANR) for backup recording when network connectivity is lost.
Can the camera operate in low light conditions?
Yes, the camera features smart IR illumination effective up to 30 metres, with a minimum illumination of 0.001 Lux in colour mode and 0 Lux in black and white mode with IR activated. The 120 dB WDR technology also ensures clear imaging in challenging lighting conditions.
What power options are available for installation?
The camera supports both 12 VDC power supply (maximum 16W) and Power over Ethernet Plus (PoE+) IEEE 802.3at Class 4 (maximum 18W), providing flexible installation options depending on your infrastructure.
Is the camera suitable for outdoor installation?
Yes, the camera has an IP67 protection rating making it fully weatherproof and suitable for outdoor installation. It can operate in temperatures from -30°C to 60°C with up to 95% humidity (non-condensing).
