Digital Watchdog - DWC-D3863WTIRW - Star-Light Plus 4K UHDoC Indoor Dome Camera with a Vari-focal Lens and IR
Product Overview
The Digital Watchdog DWC-D3863WTIRW is a high-performance 4K UHDoC indoor dome camera featuring a 3.6~10mm vari-focal lens and a 1/1.8" CMOS sensor. Utilizing Universal HD over Coax technology, it is compatible with HD-Analog, HD-TVI, HD-CVI, and legacy 960H signals, delivering 4K resolution at 15 fps or real-time 30 fps at 4MP/1080p. Equipped with Star-Light Plus™ technology for color imaging in near-total darkness, True WDR (120dB), and Smart IR up to 100 feet, it ensures exceptional forensic detail across diverse indoor lighting environments.

- • Lens: 3.6~10mm vari-focal p-iris lens; field of view: 100.3° ~ 46.4°
- • IR distance: Smart IR up to 100 ft (30.5 m); minimum illumination: 0.1 lux color, 0 lux B/W
- • Video output: 4K @ 15 fps, 4MP/1440p @ 30 fps, 2.1MP/1080p @ 30 fps; 2nd CVBS output for video testing
- • Power: DC12V/24VAC dual voltage; power consumption: DC12V – 4.27W (LED off), 6.98W (LED on); AC24V – 3.96W (LED off), 6.38W (LED on)
Key Features
This NDAA-compliant camera excels in challenging environments with Star-Light Plus™ for color vision in near-total darkness and True WDR (120dB) for high-contrast scenes. Advanced image enhancement tools like Smart DNR, De-Fog, and Highlight Masking Exposure (HME) work together to maintain clarity. Security is further bolstered by integrated motion detection and 16 programmable privacy masks.
Technical Context
Engineered for signal integrity, the unit boasts a 55dB S/N ratio and a progressive scan system for crisp, noise-free output across all HD-Analog and CVBS formats. It features auto-sensing 24VAC/12VDC power with line lock to prevent video rolling and an electronic shutter reaching 1/30,000s. The camera is globally certified (FCC, CE, RoHS) and maintains stable operation in temperatures up to 122°F.
Installation Notes
Designed for discreet indoor placement, the 0.66 lb plastic housing offers a compact footprint with easy Up-the-Coax (UTC) OSD management. It is purpose-built for seamless pairing with VMAX A1 4K DVRs, allowing users to upgrade to 4K resolution using existing cables. The installation is finalized with a 360° gimbal for precise aiming and is protected by a 5-year warranty.
