Features
The Hikvision DS-2CD2146G2-ISU is a 4 Megapixel network dome camera with a 2.8mm fixed lens which uses AcuSense to greatly reduce the number of false alarm notifications received, and produces high quality colour images in ultra-low light scenes thanks to Hikvision's Powered by DarkFighter Low Light Technology. It also features a built-in microphone and speaker for real-time 2-way audio security, and an optional interface to add an external speaker.
AcuSense Technology
The most common concerns in perimeter protection are trespassing and vehicle break-ins. AcuSense helps you to focus on these events in two ways:
- Alarm will only trigger when the preset intrusion type takes place
- Related videos are sorted by categories for easier search
Users can focus on alarms triggered by humans and vehicles while false alarms triggered by small animals or other irrelevant objects are vastly reduced.
