Technical Specifications

Imaging & Optics: The camera employs a 1/2.8" progressive-scan CMOS sensor delivering 8MP resolution at up to 30 fps in 4K (3840 × 2160). Fixed focal lens options (2.8mm or 4mm with M12 mount) provide flexible deployment, with F1.6 aperture ensuring light sensitivity and fast shutter speeds (1/3 to 1/100,000s) for motion capture in challenging conditions.

Night Vision & Low-Light: Equipped with smart IR supplementary lighting and an IR cut filter for automatic day/night switching, the camera achieves exceptional clarity in complete darkness. At 0.005 Lux in color mode, it captures usable detail in near-total darkness without IR, and 0 Lux performance with IR activation ensures uninterrupted nighttime surveillance.

Video & Compression: Supports H.265+, H.265, H.264+, and H.264 encoding with main, sub, and third streams, enabling simultaneous viewing on up to 6 channels. Flexible bitrate control (32 Kbps to 16 Mbps) optimizes bandwidth and storage efficiency without sacrificing image quality.

Smart Analytics: AcuSense AI delivers intelligent human and vehicle detection, line crossing alerts, intrusion detection, and facial recognition capabilities. These features dramatically reduce operator fatigue and false alarms caused by moving vegetation, animals, or shadows—critical for large-scale deployments.

Audio & Storage: Built-in mono microphone with G.711, G.722.1, G.726, MP2L2, MP3, and AAC-LC compression supports event recording and two-way communication. Onboard microSD slot enables local backup with automatic encryption and health monitoring, while NAS and FTP integration provide centralized archiving.

Security & Networking: TLS 1.1/1.2 encryption, HTTPS, IP filtering, and digest authentication protect against unauthorized access. Open Network Video Interface (Profile S/G), ISAPI, and SDK support enable seamless integration with enterprise management platforms including iVMS-4200 and Hik-Central.

Perspective based on aggregated IP Security Depot and affiliated engineering team experience.

The DS-2CD2383G2-IU represents a mature, field-proven design optimized for large outdoor deployments. The dual-lens strategy accommodates both wide-area detection (2.8mm) and long-range identification (4mm), with DORI ranges of 88–108m detection and 35–43m object recognition—sufficient for most perimeter security applications.

AcuSense AI is particularly valuable in outdoor environments prone to weather-triggered false alarms. By filtering alerts to human and vehicle presence, operational efficiency improves significantly. The 120dB WDR engine handles mixed lighting scenarios (sun behind subject, reflective surfaces) with minimal artifacts, and 3D DNR preserves detail while suppressing grain in low-light streams.

For large installations, the three-stream architecture enables simultaneous local recording (high-bitrate main stream), remote viewing (compressed sub-stream), and bandwidth-limited secondary sites (third stream)—reducing backbone network load. Built-in ANR (Auto Network Replenishment) ensures recorded footage is preserved locally if the NAS becomes temporarily unavailable.

PoE Class 3 (max 7.5W) keeps power consumption minimal, and the M12 lens mount allows rapid focal-length swaps in the field without tools. IP67 sealing and -30°C to +60°C operating range confirm durability in industrial and extreme climates.
