Mobile Video Recorders and Video Monitors
- With David Kirk
Contributing Editor David Kirk combines recent developments in two discrete product categories...
Video monitors with integral recording capabilities and standalone or rack-mountable video monitors - but stops short of the many camera-plus-viewfinder combinations. Video signal analysers are not covered in this review.
AJA Video Systems has announced version 2.0 firmware for its Helo Plus H.264 streaming/encoding/recording device. Available as a free download, it includes new improvements designed to streamline the delivery of live content. The update also introduces two new licensable features including simultaneous multi-channel stereo audio streaming/recording, and PlayToStream which lets users use a previously recorded program for a future streaming event. Available from the AJA support page, Helo Plus v2.0 includes new audio choices, full integration with Facebook Live, Plus SDI and HDMI status overlays. The PlayToStream license enables playout of a previously recorded show as a streaming source, even alongside another live stream being served. It can be used to record a live stream to a storage device connected to Helo Plus and play the stream as soon as the recording ends or later, which can be scheduled from the integrated web-browser GUI. Multi-channel stereo audio streaming is also available via a separate optional license that supports two simultaneous channels of stereo audio streaming/recording. With this feature, one audio stereo pair can be assigned to stream content in one language and the other to stream the same content in a different language for multilingual needs.
“Demand for streaming continues to grow across a range of industries, alongside customer expectations for more dynamic streams,” says AJA President Nick Rashby.
“Helo Plus was designed to help support this demand, enabling high-quality streaming with ultra-reliable performance and picture-in-picture and graphics functionality.”
Atomos’ new NDI HX2 firmware update, available for US$99 or €99, supports NDI HX2 transmission up to 1080p60 with Shogun Connect and Ninja V+ with Atomos Connect (1080p30 for Ninja V and Atomos Connect), while simultaneously recording in Apple ProRes or Avid DNx. Atomos provides wireless or wired NDI transmission, a live viewfinder and local recording from a single battery-operated device. “NDI is typically associated with fixed acquisition points, for example PTZ cameras,” says Atomos CEO Trevor Elbourne. “Now we are making it possible to use pretty much any HDMI or SDI-equipped camera as a mobile NDI source. It is the perfect solution for creatives who need their content delivered live to a remote device, for review, recording or transmission.” A camera and microphone can be connected by HDMI or SDI to the Atomos Connect series monitor/recorder, and then connected to a local area network using either Wi-Fi or an Ethernet cable. Once NDI is enabled to transmit, the video stream is available to any suitable device on the local area network subnet. The NDI stream can then be viewed, recorded, or used as a source for OBS or a NewTek TriCaster, and then retransmitted as part of a larger production.
Canon’s DP-V2730 monitor has a 4K UHD panel and 1,000 cd/m² full screen peak brightness, with Canon’s local dimming technology giving a black level of 0.001 cd/m². The monitor has an HDMI input and 12G-SDI terminals. Users can access four-way SDI input switching via an optional upgrade.
Datavideo’s HDR-80 is a desktop ProRes 4K recorder that captures video to two SSD drives. It has a high resolution 5 inch LCD touch screen on the front for video monitoring, device settings and configuration.

SDI is available in bitrates from HD up to 12G-SDI while HDMI connections support both HDMI 2.0 and 1.4 technology. With multiple HDMI and SDI inputs you can also record up to four 1080p sources at the same time. As one SSD fills up, the recording automatically continue on the next drive. Storage can be expanded by swapping a single drive.
Eizo’s new 31.5-inch EV3240X and 27-inch EV2740X UHD have a 3840 × 2160 pixels UHD resolution plus a pixel density of 140 and 163 pixels per inch respectively. Thanks to USB-C connectivity, the monitors have a built-in docking station that powers your entire workstation through a single cable - transmitting video and audio signals, Ethernet, connected USB devices, and supplying up to 94 W of power to a compatible device such as a laptop. The monitors have a dedicated LAN port and three USB Type-A ports plus an additional USB Type-C downstream port for connecting peripherals such as an external keyboard, mouse, or web camera.
Flanders' XMP550 is a 55 inch UHD resolution HDR and SDR reference mastering monitor built around a new QD-OLED panel with 2,000 nits peak luminance and 4,000,000:1 contrast. “The XMP550 qualifies as a Dolby Vision mastering monitor finally bringing an end to the days of compromising between smaller reference grade HDR displays and larger non-reference client displays,” says marketing manager Bryan Gordon. “The XMP550 delivers the best of both worlds with truly reference grade performance and professional connectivity in a form factor large enough for both the colourist and clients to view.”
