AI That Saves You Time

This NVR uses AcuSense technology to detect people and vehicles with high accuracy. The AI face detection lets you search recordings by face — no more scrubbing through hours of footage. Virtual tripwire and intrusion detection trigger alerts only when real threats appear, cutting false alarms from leaves, animals, or shadows.
