Vivotek AL-24E Surveillance Lens 3.9-10mm F1.5 P-Iris
Overview
The AL-24E is a varifocal surveillance lens with a 3.9-10mm focal range and F1.5 aperture designed for IP cameras requiring flexible field-of-view coverage across retail, commercial, and outdoor environments. The P-Iris (precision iris) mechanism delivers exact aperture control, maintaining consistent depth of field and image sharpness across zoom positions — a critical advantage when deploying multiple lenses on different cameras and needing predictable focus behavior. The bright F1.5 aperture reduces reliance on infrared in low-light scenes, preserving color detail and reducing power draw on cameras with IR illuminators.
Compatibility
The AL-24E is engineered for Vivotek camera models equipped with P-Iris lens mounts and varifocal lens support. Confirm exact compatibility with your specific camera model before ordering — P-Iris lenses are not backward-compatible with standard DC iris or fixed-aperture mounts. Vivotek documents specific compatible models in camera product briefs; cross-reference your camera's lens mount specification against the AL-24E datasheet to verify fit.
Installation Notes
P-Iris lenses require proper initialization during camera setup — most Vivotek NVRs and management software auto-detect P-Iris lenses, but manual iris control configuration may be necessary if deploying in third-party VMS environments. Ensure the lens is seated fully in the mount and locked before powering the camera. Do not force the focus or zoom rings; they should turn smoothly across their full range. If the iris does not respond after installation, check the camera's iris control settings and confirm the VMS or recorder recognizes the P-Iris protocol.
