Speco HLED33DTW Hd-tvi Indoor Dome Ir Camera

Product Description

The SPECO HLED33DTW is an HD-TVI indoor dome camera with built-in infrared illumination and a 2.8-12mm varifocal lens. Designed for analog HD surveillance systems, it delivers high-definition video over standard coaxial cable without requiring IP network infrastructure. The varifocal lens allows field technicians to adjust the angle of view during installation to match the coverage zone of the monitored area. This camera is appropriate for interior security applications in commercial and residential settings and is typically installed by security system integrators or low-voltage technicians.

The HLED33DTW is suited for indoor environments where flexible lens coverage and infrared night vision are required. The HD-TVI format makes it compatible with TVI-capable DVRs and hybrid recorders, allowing integration into existing analog coaxial cable runs. Typical applications include retail spaces, office interiors, hallways, and entry points where consistent low-light performance is necessary. The varifocal range of 2.8-12mm supports both wide-angle coverage and moderate telephoto framing without changing lenses.
