The compact and versatile Marshall Electronics 346 Compact HD Camera captures at progressive frame rates up to 60p, as well as interlaced, making it suitable for use in live broadcast productions, courtrooms, corporate videos, government assemblies, sportscasts, newscasts, reality television, concerts, and houses of worship. It features a 2.5MP CMOS sensor with 1920 x 1080 resolution and outputs 3G/HD-SDI as well as HDMI. Image tools include Digital Noise Reduction, Auto White balance, and digital zoom. The CS lens mount enables mounting a large assortment of available lenses as well as C-mount lenses with the included adapter. Lenses are not included and must be sourced separately.

Features specific to surveillance include motion detection and privacy mask, allowing you to have the camera trigger if it detects motion in a specific area as well as being able to mask off an area of the image from surveillance. Audio is handled by the breakout cable that lets you connect a mic- or line-level input device. The breakout cable also features an integrated joystick control for accessing and setting menu items via the on-screen menu display. In addition, you can also control the camera via RS-485 control protocol.

Related Questions and Answers

Q: 1. Is the lens threaded for filters? if so what size?

A: It is not. In general PTZ cameras rarely have lens threadings.

Q: 2. What About Focus?

A: The Marshall CV504 cameras come with a high-quality 4.0mm (85° H.AOV) prime lens, which ensures focus from near contact to infinity. Marshall offers a wide selection of high-quality M12 prime and varifocal lenses to meet the individual needs of the production, project, or application. The camera does not support Autofocus. The miniature (M12) lens that comes installed on camera is set to optimal focus position, however if lens is slightly out of focus rotate lens clockwise or counter-clockwise slightly to fine tune. Once the desired focus point is achieved, rotate the locking nut back towards the camera which will hold the lens position at optimal focus point.

Q: 3. Can the minimum pan and tilt speeds go below 1 deg/sec?

A: That would be a function of the controller it is paired with more than anything else. The compatible VS-PTC-200 that Marshall Electronics offers can be set to 3 different speeds, however there is not a setting that will go that slow. It may be possible if you set the controller to the slowest speed and manually turn the joystick gently though. This sounds like a very specific function you are looking for, feel free to email us directly at provideo@bhphoto.com so we can assist you further.

Q: 4. Description says SDI and HDMI output but the images only show a labelled SDI port.. where's it hiding?

A: The image of the Marshall Electronics CV348 Compact 3G-SDI/HDMI POV Camera is not the version with both outputs. Rest assured, this model does have both outputs.

Q: 5. Can I run BNC and HDMI simultaneously, or just one at a time?

A: A signal can be sent simultaneously through the HDMI and SDI ports.

Q: 6. How much power is needed if powered over a PoE switch? Could you recommend a adequate switch. Trendnet etc?

A: I am sorry to say we do not have exact figures on how much power is required. That being said, we feel confident it will work with a product like the TRENDnet TPE-082WS 10-Port Gigabit PoE+ Managed Switch, B&H # TRTPE082WS. https://bhpho.to/2BgWjzy

Q: 7. Can this also be operated with a joystick?

A: Yes, the Marshall Electronics CV620-TBI 20x Tracking PTZ Camera (Black) can be operated by a joystick controller. The camera offers ONVIF, VISCA, VISCA Over IP, and PELCO D protocols. A controller example is the Marshall Electronics VS-PTC-IP IP PTZ Camera Controller. See the link below: https://bhpho.to/42hijVt

Q: 8. Can the sdi and hdmi output work simoultaneously?

A: Yes, the Marshall Electronics CV508 Micro HDMI/3G-SDI POV Camera can output simultaneously to both SDI and HDMI.

Q: 9. How does this camera do in low-light/IR situations?

A: The camera Marshall Electronics CV346 would work well in low light or in IR setups. Here are some of the cameras settings for Night mode. MODE: Set camera to either color mode or B&W mode. (Day, Night) DAY: When set to DAY mode, camera stays in color and IR cut filter is engaged. NIGHT: When set to NIGHT mode, camera stays in B&W and IR cut filter is removed. NIGHT COLOR: When on, camera stays on color mode. Night (B&W) can be selected from this mode. (On, Off)

Q: 10. Can anyone speak to the low-light performance of this camera's image sensor? Planning to use these models in a Synagogue install, where portions of the service will have dimmed room light. Not entirely dark.

A: Marshall lists this for use, among other things, for houses of worship. Users have reported excellent over all image quality.
