Tech Roundup: PTZ Cameras and Streaming Devices

Developments in the past two years have catapulted conferencing to the killer Internet app while at the same time making live streaming a matter of survival in the house of worship arena. AV manufacturers have responded with cameras, streaming hardware and capture devices that integrate sophisticated capability with ease of use. The items surveyed here illustrate those current trends and highlight that innovative industry response to what have been the most challenging of times.

The conferencing solution for small to medium sized rooms is the 1 Beyond Hawk with its dual PTZ cameras that switch between wide angle and close-ups on the participants. Each camera has a 12x optical zoom that can bring in small detail while using the unit’s built-in audio-locating microphones to find the featured presenter from one moment to the next. A variety of room microphone systems can be used to route the far end audio to the device for echo cancellation.

The AJA Helo is an H.264 streaming and recording stand-alone appliance that can record H.264 files to either SD, SDHC or SDXC cards, USB storage and NFS/CIFS mounted network based storage simultaneously. It takes signals on its 3G-SDI and HDMI source inputs and encodes 2-channel stereo audio up to 24-bit 48kHz. It also has error logging for quick analysis of streaming issues and a web based GUI preview window. The device is small enough to travel easily and fit just about anywhere.

Designed to capture video up to 1080P and provide 3G SDI, HDMI, USB 3.0, and HD video over IP, the Apantac AP-1080P-PTZ-20x has also incorporated the NDI protocol into its capabilities. This technology allows video and audio sources to be shared bi-directionally across a network and it gives the camera a wide range of applications. The camera supports NDI|HX, USB, IP, HDMI and SDI outputs. Control options include standard IP VISCA, serial, TCP/ IP, and Pelco-P/D control protocol.

The Atlona AT-HDVS-CAM-HDMI can be used in conferencing, capture and online learning while its video signal is sent out on HDMI and USB ports simultaneously. It integrates with the Omega Series and AT-OME-MS42-KIT for a complete, automated conferencing system. The HDMI output can be used with a video conferencing codec, lecture capture appliance, or PC equipped for video capture. Its auto-focused video can go up to resolutions of 1080p/60 over HDMI and 1080p/30 for USB 2.0. The system is capable of H.264 or H.265 streaming over IP with support for RTMP and RTSP protocols.

When connected to any HDMI video source, the AVPro Edge AC-MXNET-1G-E encodes the audio/video signal to a multicast data format capable of being routed to any decoder endpoint within the installation project. The unit connects via category cable (CAT 6 recommended) to the MXNet Switch (AC-MXNET-SW48) or any other compatible multicast-capable managed L3 network switch. It then transmits a full 4K 4:4:4 60Hz HDMI video signal along with audio, control, power, and HDR metadata signals.

The Aurora VPX-TC1 uses Aurora’s new Mimix CODEC technology to stream video and graphic images at resolutions up to 4K60 4:4:4 over 1G networks. It can be configured as a transmitter or receiver and with no fan, it uses as little as 8W power producing only a single frame of latency at the output. When the unit is used as a transmitter and connected to an off-the-shelf 1G RJ-45 Ethernet switch audio, video, data, and control can be sent securely to one or many receivers. When set up as a receiver, a user can select the local HDMI inputs or an IP source.

Whether in a permanent installation or out on the road, the Barix MA400 provides a link between devices using standard SIP protocol in peer-to-peer mode or through a SIP server.
