ACTi PLEN-0101 4.2mm Fixed Focal Length Lens
Overview
The ACTi PLEN-0101 is a 4.2mm fixed focal length lens with f1.8 aperture designed for integration into compatible ACTi camera platforms. The fixed 4.2mm focal length delivers a wide field of view suitable for corridor, entrance, and overhead deployment scenarios where you want consistent coverage without variable zoom complexity. Manual focus allows field adjustment after installation if mounting position shifts or environmental factors affect initial focus lock. Day/night operation means the lens works across full lighting ranges without swapping optics or filter cartridges—a practical advantage in 24/7 surveillance where camera repositioning is disruptive.
Compatibility
This lens integrates with ACTi camera systems that support fixed focal length lens attachments and manual focus adjustment. Verify your ACTi camera model supports CS-mount or equivalent lens attachment before purchase. The lens is powered via standard PoE (802.3af), so no separate power supply is required at the camera location—existing PoE infrastructure carries both data and power through a single cable run. This simplifies installation in retrofit environments where dedicated power lines are unavailable or impractical.
Installation Notes
Manual focus requires field adjustment after mounting. Ensure camera is positioned at final installation height and distance before focusing to avoid misalignment. The f1.8 aperture collects sufficient light for low-illumination indoor spaces, reducing reliance on IR in mixed lighting scenarios. Day/night operation supports both continuous ambient-light operation and IR-augmented low-light imaging depending on camera capability.
