Pelco LENS iCS 3.9-10mm f1.5 1/1.8 - EG3Z3915TCSMPWIR-MSI

Pelco EG3Z3915TCSMPWIR-MSI Varifocal Surveillance Lens

The Pelco EG3Z3915TCSMPWIR-MSI is a 3.9–10mm varifocal lens designed for 1/1.8" image sensors. The f1.5 aperture delivers usable detail in low-light scenes — meaningful when you're recording a dimly lit corridor or a loading dock at dusk without artificially brightening the image. Varifocal construction lets you dial in the exact field of view your camera needs at installation without swapping glass.

Compatibility

This lens is engineered for Pelco camera systems that accept 1/1.8" sensor format lenses. Confirm your camera's sensor size and mount type before purchase — incorrect sensor size or mount will result in poor focus, vignetting, or physical incompatibility. If you are unsure whether your current camera supports this lens, contact the camera manufacturer's technical support or your system integrator for verification.

Installation Notes

Varifocal lenses require focus and iris adjustment at install time. Plan for a 10–15 minute setup window per camera to dial in focus across your depth of field and confirm even illumination across the frame. Ensure the lens barrel clears any dome or turret housing before final mounting. Test focus at multiple distances (near field, mid-range, far field) if the scene contains objects at varying depths.
