Marshall Electronics CS1150-8MP 8MP Varifocal Cs Mount Lens

Product Description

The Marshall Electronics CS1150-8MP is an 8-megapixel varifocal CS-mount lens designed for use in professional video surveillance and IP camera systems. With an 11-50mm focal length range and a fast F1.4 maximum aperture, this lens delivers sharp, high-resolution imaging across a wide range of zoom positions. The varifocal design allows technicians to manually adjust both focal length and focus independently, making it well suited for installations where precise field-of-view tuning is required. It is installed by security integrators and low-voltage technicians working on NVR-based camera systems.

This lens is intended for CS-mount IP cameras used in commercial and residential surveillance installations. The 11-50mm focal range makes it appropriate for medium to long-distance monitoring applications, such as parking lots, building perimeters, retail floors, and corridors. The F1.4 aperture supports improved low-light performance, which is valuable in environments without consistent ambient lighting. Systems paired with NVR platforms benefit from the resolution ceiling this lens supports at 8MP.

Key Features

• 8MP optical resolution supports 4K-class IP camera sensors
• 11-50mm varifocal focal length allows flexible field-of-view adjustment on-site
• F1.4 maximum aperture improves image quality in low-light conditions
• CS-mount interface for compatibility with standard CS-mount camera housings
• Independent focus and zoom adjustment for precise installation tuning

Compatibility

Designed for use with CS-mount IP cameras in NVR-based surveillance systems. Specific camera model compatibility should be verified against the camera manufacturer's lens mount and flange focal distance requirements prior to installation.

Installation Notes

This lens is installed by low-voltage security technicians and surveillance system integrators. Before mounting or adjusting the lens, ensure the camera is powered down and secured in its final position. Use the varifocal adjustment ring to set the desired focal length, then fine-tune the focus ring for sharpest image output at that zoom setting. Local codes governing low-voltage wiring and security system installation, such as those referenced in NEC Article 725, may apply depending on jurisdiction.
