Marshall CV346 2.5 Megapixel Full HD Surveillance Camera - Color - Black

The Marshall CV346 is a professional-grade surveillance camera designed for reliable security coverage in demanding environments. Delivering a crisp 2.5 megapixel color image with 4:2:2 color sampling, this camera ensures accurate color reproduction and detailed video that helps with identification and incident review. Featuring a 1/2.8" sensor and an interchangeable CS/C lens mount (lenses sold separately), the CV346 offers flexible installation options to fit a wide range of surveillance scenarios—from storefronts and offices to parking lots and entryways. It provides 3G/HD-SDI output for clean, high-quality video transmission over existing infrastructure, and it supports Full-HD resolutions up to 1080p and 1080i, as well as 720p, with multiple frame rates to balance image quality and bandwidth. Remote control through RS485 (Visca) or the on-screen display (OSD) joystick enables precise tuning of exposure, white balance, and other camera parameters without on-site adjustments. This combination of advanced imaging, flexible mounting, and convenient control makes the CV346 a compelling choice for security deployments that demand reliability, clarity, and easy integration into modern surveillance systems.

• High-definition 2.5 MP sensor with 1/2.8" size delivers crisp, detailed color video across a wide range of lighting conditions. The 4:2:2 color sampling preserves color fidelity during video processing, making it easier to distinguish colors and identify objects or individuals in footage.
• 3G/HD-SDI output offers a clean, low-latency digital signal compatible with professional security encoders, DVRs, and hybrid systems. This interface supports long cable runs and minimizes signal degradation, helping maintain image quality over extended installations.
• Interchangeable CS/C lens mount (lenses sold separately) gives installers the flexibility to select the perfect field of view and depth of field for a given space. Swap lenses to optimize coverage—from wide storefront entrances to focused indoor corridors—without changing the camera body.
• Full-HD video support up to 1920x1080p, 1920x1080i, and 1280x720p with multiple frame rates (60, 59.94, 50, 30, 29.97, 25, 24, 23.98 fps). This versatility lets you balance motion clarity and bandwidth to fit your network constraints while preserving detail in important scenes.
• Remote adjustment via RS485 (Visca) or the on-screen display joystick enables convenient, centralized tuning of image and video settings. Adjust exposure, white balance, gamma, noise reduction, and other essential parameters from a control room or remote terminal without visiting the camera location.

How to Install Marshall CV346

Installing the CV346 is straightforward for professional security setups. Begin by selecting a mounting location that provides clear coverage of the intended area and, if using a lens with a narrow field of view, ensure the mount position accommodates the desired perspective. Assemble the camera with a CS/C lens (not included) that matches your required field of view, and securely attach the lens to the interchangeable mount. Connect the camera's 3G/HD-SDI output to your recorder, monitor, or video encoder using high-quality SDI cables that comply with your system's specifications. Power the camera according to the supplied electrical requirements and verify a stable video feed at the connected equipment. Use the RS485 (Visca) interface or the OSD joystick to perform initial calibrations: set the correct resolution, frame rate, white balance, exposure, gain, and any required noise reduction or gamma adjustments. If integrating with a larger surveillance system, configure the camera in your video management software (VMS) or control system to enable remote monitoring, scheduling, and automated routines. Finally, perform field tests to confirm proper focus across the scene, confirm that the lens is correctly populated within the image, and ensure the camera maintains consistent performance under varying lighting conditions.
