The Hikvision DS-2CD2366G2-IU (HIK-2CD2366G2IU) is a 6MP outdoor AcuSense gen 2 turret camera. Empowered by deep learning algorithms, Hikvision's AcuSense technology can distinguish people and vehicles from other moving objects, such as falling leaves or small animals. While originally created with the purpose of preventing false alarms, AcuSense technology offers users several other key benefits such as advanced analytics, active deterrence and timely alerts.

The most paramount feature with the AcuSense gen 2 cameras is the analytic alert which will generate alarm events that are searchable when reviewing recorded footage for specific incidents. This saves many man hours of wasted time reviewing irrelevant video trying to identify an event, saving the end customer time and money. The inclusion of a built-in microphone allows for real-time audio security so the user may hear the intruder when the alarm is triggered.

Hikvision AcuSense Technology

AcuSense technology helps you take security to the next level with accurate, real-time threat detection that distinguishes people and vehicles from other targets.

Take your security to the next level

Hikvision’s AcuSense technology embeds deep-learning algorithms into security cameras and video recorders to equip businesses and homeowners with smart tools to take security to the next level, both indoors and outdoors.


AcuSense technology detects intrusion threats in real time and triggers alerts to users’ mobile phones for faster response.

More accurate

AcuSense technology differentiates people and vehicles from other moving objects, allowing security teams to focus on real threats. High-end camera models with AcuSense also use Hikvision’s ColorVu technology for 24/7 color imaging.

More efficient

AcuSense technology applies labels to recorded video footage with people and vehicles, speeding up video searches, minimizing manual effort, and reducing overall security costs.

Easy to use

AcuSense-enabled smart cameras are installed quickly and are as easy to configure as conventional security cameras. The technology puts AI security at everyone’s disposal.

How does AcuSense work?

AcuSense technology uses advanced machine vision AI algorithms built into Hikvision security cameras and video recorders to boost home and business security. Check the diagram below for details.
