DHIL-D51TLM-A-28D – 5MP Smart Dual Light Eyeball Camera with Built-in Mic (2.8 mm, IP67, IR & Warm Light 20m)

Product Overview

The DHIL-D51TLM-A-28D (HAC-HDW1500TLM-IL-A-S2) is a high-performance 5 Megapixel HD analog eyeball/dome security camera engineered for commercial, residential, and perimeter video surveillance installations. Featuring advanced Smart Dual Light technology, this camera intelligently balances discreet infrared surveillance with vivid full-color night imaging. By default, the camera utilizes IR illumination to monitor dark environments silently; upon target detection in monitored zones, it automatically triggers warm white light LEDs to capture full-color evidentiary details up to 20 meters (65.6 ft).

Equipped with a wide-angle 2.8 mm fixed lens and a high-sensitivity image sensor, it delivers sharp, high-definition video at 5MP resolution (2880 × 1620 at 25 fps) in 16:9 aspect ratio across HDCVI, HDTVI, AHD, and standard CVBS formats via multi-format switchable BNC output. The unit features an integrated high-fidelity microphone for single-coaxial audio transmission, digital wide dynamic range (DWDR), and 3D/2D digital noise reduction. Built into an IP67 weatherproof metal and plastic hybrid enclosure, it operates reliably across extreme temperatures from -40°C to +60°C.
