ACTi PLEN-4101 1.9mm Fixed Focal Lens
Overview
The PLEN-4101 is a 1.9mm fixed focal length lens with F2.8 fixed iris, designed as a board-mount optic for ACTi 8MP camera bodies. The wide-angle focal length delivers expanded field of view suitable for close-proximity and interior surveillance where you need to cover large areas from a fixed position without lens adjustment. Fixed iris construction (F2.8) holds exposure constant across varying lighting conditions without mechanical drift — a key advantage for surveillance installations where you cannot service the camera regularly.
Compatibility
The PLEN-4101 is a board-mount lens compatible with ACTi 8MP camera platforms that accept interchangeable fixed focal lenses. Verify your specific ACTi camera body accepts this lens form factor before ordering — board-mount lenses are not universal across all ACTi lines. PoE power delivery to the camera eliminates the need for separate power runs to the lens itself.
Installation Notes
As a board-mount lens, the PLEN-4101 requires removal of the camera's factory lens and installation onto the camera's lens mount board. This is not a field-replaceable accessory for end users — it demands camera disassembly and is best performed by an integrator or trained technician familiar with camera optics. No additional power or wiring is required beyond the camera's existing PoE connection. Ensure the camera body and surrounding enclosure allow physical access to the lens mount before committing to this upgrade.
