Impressions:
If the Marshall Electronics CV620-NDI looks familiar, it’s because it is. It shares both platform and feature set with the Newtek NDIHX-PTZ1 and the Lumens VC-A50PN. This not necessarily a bad thing, considering Newtek created NDI and would know what would be ideal for use with Newtek brand products. That said, the Marshall Electronics CV620-NDI did not disappoint.
Although a bit larger and more “plastic-y” looking than the competition, the Marshall quickly proved that looks are truly skin deep. From out-of-the-box to facing talent in our studio, the image produced by the Marshall Electronics CV620-NDI quickly stood out. Colors were wonderfully saturated, warm and well contrasted. If the Marshall didn’t arrive factory-sealed, we would have guessed we were sent a ringer!

Like the PTZOptics camera, the Marshall integrates seamlessly with vMix software for easy control without the need for a standalone controller.

Manually-Adjusted Settings
A lot like the color reproduction of the JVC KY-PZ100, the Marshall produced wonderful color reproduction and needed only minimal adjustments in our “manual-mode” tests. It was honestly debatable which camera between the two looked better. Once those adjustments were made, the large, colorful, IR remote made accessing a simple on-screen menu relatively easy.
As with all the native IP-enabled cameras here, additional menu settings can be accessed via a browser interface as well. Marshall Electronics did a good job designing a clean and elegant interface. For the more novice users, settings and functions are easy to find and adjust. The only negative that we found in this regard is the necessity of installing Newtek NDI tools; having to register the camera online in order to use NDI.
Despite having to curtsey to Newtek in order to use NDI features, it is not a deal-breaker at all. The added software gives users some nice additional production tools. Once we installed this software and rebooted vMix, we found some magic in connecting via NDI. An additional bonus to using NDI, when connecting with the Marshall Electronics CV620-NDI, is that the IP address settings automatically populated within vMix for control.
technology; however, it must be activated upon initial use.
Camera Control
When controlling the Marshall PTZ camera in vMix, we found movements to be smooth; and tracking predictable. We had a similarly positive experience using the IR remote as well. Presets were called up quickly with the help of the synchronous pan-tilt-zoom motor. A lot of people don’t realize how nice it is to see a camera perform three movements in a single, smooth motion.

Marshall Electronics did a great job with the execution on their CV620-NDI. Rich colors, NDI HX and a nice interface await a lucky producer. It was a bit of a letdown that fit and finish was not as excellent as the actual performance of the camera.
