ACTi - K31 - 2MP Deep Learning AI f2.8mm Fixed Bullet with IR LED 50m, WDR 130dB
Product Overview
The ACTi K31 is a 2MP outdoor bullet camera designed for AI-assisted video surveillance. It combines a 2.8mm fixed lens, deep learning AI, 50m IR illumination, and Extreme WDR to support reliable monitoring in low-light and high-contrast environments.
Key Configuration
2 Megapixel fixed bullet camera; f2.8mm fixed lens; IR LED range up to 50m; Extreme WDR rated at 130 dB; DORI range of 42 / 16.8 / 8.4 / 4.2m; IP68 weatherproof, IK10 vandal-proof, and UL Listed.
Key Features
• Deep Learning AI supports intelligent surveillance applications
• Smart Motion Detection helps improve event-based monitoring
• 50m IR LED illumination supports nighttime visibility
• 0.003 lux color minimum illumination supports low-light color imaging
• IP68 and IK10 ratings support outdoor and vandal-resistant installation
Technical Context
The K31 combines deep learning AI with Smart Motion Detection to help distinguish relevant events in monitored scenes. Its 130 dB Extreme WDR helps maintain image detail in areas with strong backlighting or high contrast, while IR illumination extends surveillance coverage in darkness.
Installation Notes
The camera is designed for outdoor use with IP68 weatherproof and IK10 vandal-proof protection. Use the DORI values of 42 / 16.8 / 8.4 / 4.2m when planning placement for detection, observation, recognition, and identification coverage.
