4K High-Resolution Surveillance in a Versatile Turret Housing

The Hikvision 8 MP AcuSense Fixed Turret Network Camera (DS-2CD2383G2-I / DS-2CD2383G2-IU) delivers sharp, reliable 4K video surveillance for retail stores, commercial properties, offices, and residential perimeters. Equipped with a 1/2.8" progressive scan CMOS sensor, it captures high-definition footage (3840 × 2160 @ 20 fps and 3200 × 1800 @ 30 fps) with low-light sensitivity down to 0.005 Lux. Available in 2.8 mm (107° FOV) for wide area coverage and 4 mm (87° FOV) for longer identification reach, its flexible 3-axis turret base (pan 0° to 360°, tilt 0° to 75°, rotate 0° to 360°) ensures easy wall or ceiling alignment.

Intelligent Target Classification and Clear Audio Recording

Integrated with deep-learning AI and high-clarity audio hardware, this turret camera provides proactive security and comprehensive situational awareness:

  • AcuSense Perimeter Analytics: Distinguishes human and vehicle targets during line crossing and intrusion detection events, significantly filtering out false alarms caused by moving foliage, rain, and shadows.
  • Integrated Noise-Filtering Microphone (-U Model): Captures clear ambient audio while filtering out background environmental noise.
  • Smart 30-Meter Infrared Night Vision: 850 nm Smart IR automatically adjusts illumination intensity to prevent overexposure when subjects approach the camera.
  • 120 dB True WDR: Balances high-contrast lighting conditions, harsh sunlight, and glare around entryways and large windows.
  • Face Detection: Automatically detects faces within the scene to facilitate rapid security playback and logging.

Rugged IP67 Protection and Efficient PoE Operation

Built for continuous indoor and outdoor performance, the camera features an IP67 weather-resistant housing operating reliably from -30 °C to 60 °C. It supports local storage up to 512 GB via an onboard microSD card slot and powers smoothly over standard PoE (802.3af, max 7.5 W) or 12 VDC.

FAQ

What is the night vision range?

The camera provides 30m of IR night vision. In complete darkness, the IR LEDs illuminate the scene so you get clear black-and-white footage without any ambient light.
How much local storage can I use?

The camera has a MicroSD card slot that supports cards up to 512GB. With H.265+ compression, you can store weeks of footage locally without an NVR.
Does this camera record audio?

The -IU model features a built-in microphone with environmental noise filtering that captures clear on-site audio alongside the video feed. If audio recording is not required or restricted by local privacy regulations, the standard -I model without a microphone is also available.
Can this camera be installed in harsh outdoor weather?

Yes. The camera is housed in a durable IP67 weather-resistant casing designed to withstand heavy rain, dust, and extreme temperatures ranging from -30 °C to 60 °C (-22 °F to 140 °F).
