Marshall CV344 2.5MP Full HD Surveillance Camera - Color

The Marshall CV344 delivers professional-grade surveillance performance in a compact, versatile package. Built around a 2.5 megapixel 1/2.8" sensor, this camera captures crisp, color-rich video at Full HD resolutions, ideal for monitoring entrances, hallways, cash desks, and parking areas. With a 3G/HDSDI output, you can transmit high-quality video with minimal latency to your recording hardware, whether you’re integrating with a DVR, NVR, or broadcast-grade monitor. The CV344 is designed for installers who demand flexibility: an interchangeable CS/C lens mount (lenses sold separately) lets you tailor the field of view to your site, reducing the need for multiple camera models on a single project. In addition to robust hardware, remote control through RS485 (Visca) or an OSD joystick provides precise, on-site configuration, making the CV344 a reliable choice for both security deployments and professional video installations. Whether you’re updating a legacy system or building a new security network, this camera combines image quality, control, and adaptability in a compact form factor that integrates seamlessly into a wide range of environments.

• 2.5 Megapixel Full HD sensor for detailed captures: The CV344’s 1/2.8" sensor delivers sharp 1080p imagery with strong color fidelity, enabling clearer identification of faces, license plates, and subtle scene details. The higher pixel count compared with standard HD cameras means you get more usable footage during critical events, helping operators review incidents with confidence and accuracy.
• 3G/HDSDI output for professional-grade video transmission: With a native 3G/HDSDI interface, the CV344 can send high-quality video over standard BNC connections to compatible DVR/NVR systems or broadcast equipment. This streamlined output minimizes interference and signal degradation over longer cable runs, making it ideal for mid-to-large installations or facilities that require reliable, real-time footage without compression artifacts.
• Interchangeable CS/C lens mount (lenses sold separately) for installation flexibility: The ability to swap lenses lets you optimize the camera’s field of view for the specific site. Whether you need a wide-angle view to cover a lobby or a telephoto perspective for distant perimeters, you can tailor the setup without replacing the camera body. The modular mount also simplifies maintenance and future upgrades as your surveillance needs evolve.
• 4:2:2 color sampling supports accurate color reproduction: The CV344 uses 4:2:2 color sampling to preserve color information across the video stream. This results in more faithful color rendering and better performance when color grading or zooming into scenes for detail analysis, contributing to more reliable recognition tasks and lower noise in post-processing.
• Flexible frame rates and full-HD resolutions for adaptable performance: The camera supports full-HD resolutions of 1920x1080p, 1920x1080i, and 1280x720p, with frame rates including 60, 59.94, 50, 30, 29.97, 25, 24, and 23.98 fps. This broad selection allows you to prioritize smooth motion in fast-moving environments (sports, loading docks) or optimize bandwidth usage in networked deployments, ensuring you get clear footage while balancing storage and bandwidth considerations.

How to install Marshall CV344

Installing the CV344 is straightforward for technicians familiar with typical CCTV or broadcast infrastructure. Start by selecting the correct CS/C lens for your scene. If you’re working in a wide lobby or entrance, a shorter focal length will maximize coverage, while a longer focal length is better for distant monitoring or sensitive entry points. Attach the chosen lens to the camera’s interchangeable mount (CS or C-mount lenses are not included and are sold separately). Ensure the lens is properly secured and that any required infrared or lighting considerations are accounted for in your installation plan.

Next, mount the camera to your preferred bracket or ceiling mount using industry-standard hardware. The CV344’s compact form factor and robust construction make it suitable for a variety of mounting options, from wall-mounted enclosures to ceiling drops. Route the 3G/HDSDI cable to your video recorder or monitor, taking care to minimize cable stress, especially in high-traffic areas or locations with potential vibration. If you plan to use remote control features, connect the camera’s RS485 port to a compatible controller or a computer-based Visca controller, and ensure termination resistors are correctly configured for your RS485 network.

After physical installation, power the camera according to your region’s electrical standards and verify that the video feed is live. Use the OSD joystick to access the camera’s on-screen display settings and configure essential parameters such as resolution, frame rate, brightness, contrast, and color saturation to suit the environment and lighting conditions. If you’re integrating with a wider security system, enable remote control via RS485 Visca to adjust zoom, focus, or other lens-related settings without returning to the camera site.

Finally, perform a functional test: check edge details during daylight and low-light conditions, verify color accuracy, and confirm the camera’s field of view matches your design plan. If you’ve swapped lenses, re-check focus at the working distance and adjust accordingly. The CV344’s flexibility makes it a future-proof choice for evolving installations, so you can swap lenses or reconfigure settings as your security needs change without replacing the camera hardware.
