ACTi PLEN-0131 Varifocal Manual Focus Lens
Overview
The PLEN-0131 is a 3.3–9mm varifocal manual focus lens designed for fixed-position surveillance deployments where field-of-view adjustment is needed without motorized complexity. The 3× zoom range supports both wide ambient coverage and tighter subject framing — useful when a single camera must cover multiple zones or when installation constraints force compromise between coverage depth and breadth. CS mount thread pattern ensures compatibility with ACTi 2MP camera bodies. Manual focus mechanism eliminates servo motor power draw and failure modes, making it the correct choice for reliable, maintenance-light installations in retail, office, and industrial corridors.
Compatibility
The PLEN-0131 integrates with ACTi surveillance cameras equipped with CS mount threads and 2MP sensor resolution. It functions in day/night environments when paired with ACTi infrared-enabled camera models. Field-of-view and depth-of-field performance depend on the specific camera sensor size; confirm CS mount and 2MP specification with your camera model before ordering. Consult the ACTi product datasheet or integrator documentation to verify mount compatibility on your chosen body.
Installation Notes
Manual focus requires on-site adjustment after mounting — use a test pattern or live VMS feed to dial in sharpness across your expected subject distance. Once set, mark the focus ring with tape or paint to prevent accidental drift. The varifocal range (3.3–9mm) allows field-of-view tuning without lens replacement, reducing spares inventory on multi-camera deployments. Ensure the camera body is powered and accessible during commissioning so you can verify focus quality before final ceiling/wall sealing.
