The HDBaseT system integration solution is very popular in the professional audio-visual field. It is sought after by many integrators and users for its low cost, easy installation, easy maintenance, multi-signal fusion and long-distance transmission. Live broadcast, or education recording, telemedicine training, and even radio and television visual broadcasting and other application scenarios in various industries are where HDBaseT shines.Today, let's take a look. To what extent can the HDBaseT system solution be simplified?What equipment can a typical HDBaseT conferencing video system use to integrate easily?Front-end signal collection 1: Choose HDBaseT PTZ camera according to local conditionsYou must know that in the field of professional AV audio-visual integration, the feature of HDBaseT is that it can transmit common signals such as video, camera control, power supply and tally through a CAT-6 network cable. Therefore, if you want to integrate the easiest HDBaseT system solution, of course It is to choose a camera with HDBaseT function implanted for front-end signal acquisition.Because this can save the trouble of powering it separately, and it can also be controlled and operated through the network cable.Datavideo Yangming's PTC-140T and PTC-150T are HDBaseT PTZ cameras, which can truly realize the freedom of installation.Because the camera itself has the HDBaseT function, there is no need to arrange a power outlet for it, and it can be installed anywhere.It can not only be used as a common camera on a tripod, but also can be installed on the wall or directly hoisted on the top of the room; plus HDBaseT supports a transmission distance of up to 100 meters, so there is no strict limit on the integration space. Suitable for large occasions.Each camera can be connected to the signal processing center with only one CAT-6 or above network cable, which greatly reduces the cost of consumables, the difficulty of installation and complicated engineering wiring for the entire solution, saving time and effort; and through this With a single network cable, the operator can also control each camera independently through the control unit, including camera parameters such as aperture, white balance, focus, shutter, gain, and push-pull panning.If you want to upgrade the overall system in the future, for example, if you replace the high-definition PTZ camera with a 4K PTZ camera, you don’t need to go over the wall and dig the wall. The wires embedded in the original project can still be used, and only the equipment at both ends can be replaced, which is very convenient .PTC-140T and PTC-150T HDBaseT PTZ CamerasDatavideo Yangming's PTC-140T and PTC-150T HDBaseT PTZ cameras both use 1/2.8-inch CMOS, and the shooting resolution can reach full HD resolution of 1920x1080p60, which can capture high-quality and clear images anytime, anywhere;Both PTC-140T and PTC-150T have 2D/3D noise reduction function, which can take clear pictures even in the auditorium or in the dark place with weak light;PTC-140T has 20x optical zoom and 10x digital zoom, and the shooting angle width reaches 54°, which is suitable for multi-camera setup for shooting video conference or training site; PTC-150T has 30x optical zoom, 63° wide-angle shooting , it is very suitable for installation in the high place of the large auditorium, or as the farthest camera position in the large conference forum or the conference site. Push the close-up shot to the main character picture;PTC-140T also has the H.264/H.265 video encoding and streaming function, which can independently broadcast live signals, and act as a security camera in the work of live broadcast of important conferences, effectively backup live signals, and ensure the smooth progress of live broadcast of conferences.PTC-140T also has the H.264/H.265 video encoding and streaming function, which can independently broadcast live signals, and act as a security camera in the work of live broadcast of important conferences, effectively backup live signals, and ensure the smooth progress of live broadcast of conferences.What if the user already has an ordinary camera and wants to use it as a front-end signal acquisition device, but he does not want to abandon it but wants to integrate the application scheme of long-distance transmission control?Then we also recommend the use of HDBaseT, as long as an HDBaseT electric remote control pan/tilt is used.Front-end signal collection 2: Turn ordinary cameras into HDBaseT camerasThe PTR-10T MARK II motorized remote control pan/tilt head with HDBaseT technology from Datavideo is an efficient tool that can turn your handheld camera into an unattended PTC camera.As long as the camera is installed on this electric remote control head, the camera can be moved left and right, up and down; by using the zoom data sensor ZEK-1, the camera can be pushed and pulled, and the shooting parameters of the camera can be set to realize the remote control function.Because of the HDBaseT function, it can also transmit high-definition video, camera control, camera power supply and tally signal to this camera via a CAT-6 network cable.PTR-10T MARK II is compatible with most brands of cameras on the market, and also has tally light indicator functionGenerally, at the scene of conference shooting or training recording, appropriate collection of live sound will be considered and added to the recording or live broadcast content, so the sound environment of the scene needs to be relatively quiet.The PTR-10T MARK II can operate silently, reducing noise interference in the shooting environment, leaving a quiet space for people to speak.Moreover, this electric remote control head weighs 3.4 kg and is made of aluminum alloy structure, it can support cameras weighing up to 4 kg.Overall, it is light in weight and can be easily placed in any corner of the venue, or securely and securely mounted on the wall or ceiling.As a signal processing center that collects, guides, switches, and redistributes front-end signals, it plays a particularly important role in system integration.HDBaseT itself has the convenience of transmitting multiple signals with one network cable. If the signal processing center of the entire system can simultaneously perform the functions of director switching, camera control, live broadcast, and video recording, wouldn’t the integrated design of the entire HDBaseT system be easier and simpler?Signal processing center: choose efficient and integrated HDBaseT broadcasting equipmentWith the original intention of being convenient for integrators, engineers and users, Datavideo Yangming has designed a highly integrated multi-functional integrated device - 4-channel HDBaseT mobile conference recording and broadcasting machine HS-1600T (MARKII version).This all-in-one device supported by HDBaseT technology is designed with a mobile portable suitcase. It is not only suitable for use in various conference rooms, lecture halls, school classrooms or training rooms, even if it is moved outdoors or in temporary conference sites. The system can be set up quickly and the usage is very flexible.HS-1600T (MARKII version) can be a one-stop solution for shooting live recording and broadcasting.It has multi-channel camera control, video signal switching, audio and video synchronization, multi-screen monitoring, live broadcast and video recording functions.The built-in PTZ camera control can operate 3 Datavideo HDBaseT PTZ cameras or electric remote control PTZ at the same time. Each camera can be preset with 4 preset positions, which is convenient for the director to quickly recall the preset camera positions.Built-in dual encoding function, the video content can be quickly broadcast live to two different live broadcast platforms after H.264 encoding, one-key switching between horizontal and vertical screens, one-key live broadcast, and one-key SD card recording functions, which can provide users with convenient and intuitive. operating experience.Usually when we are doing audio and video system integration, if none of the system equipment has HDBaseT function or only individual equipment has HDBaseT function, then adding HDBaseT audio and video codec when designing the entire system can easily solve the system compatibility and longevity. There are two major problems with distance transmission.Auxiliary tool for long-distance transmission: HDBaseT video and audio codecDatavideo Yangming has a variety of HDBaseT codecs.Among them, HBT-5 and HBT-15 are encoders with Power over Ethernet (PoE) function.When HBT-5 uses CAT-6 network cable, the maximum transmission of video at 1080p can reach 60m, and at 4K@30p, it can be transmitted to 35m; HBT-15 is a 4K HDBaseT video and audio encoder, which can transmit 4K 2160P video signals up to 100m .In order to meet the requirements of different distances and number of channels in various application scenarios, Yangming HDBaseT decoders have HBT-6, HBT-11, HBT-12, HBT-16, HBT-30, HBT-50 and other options, among which HBT-6, HBT-11, HBT-12, HBT-16 are all single-channel decoders. For detailed parameters, please visit www.datavideo.cn for product specification comparison.For multi-channel codec, there are HBT-30 three-channel HDBaseT video and audio decoder and HBT-50 four-channel HDBaseT video and audio decoder to choose from. HBT-30 can output HDMI, RS-422 and IP control signals at the same time; HBT-50 Supports simultaneous transmission of SDI signals (up to 1080p60) and HDMI signals (up to 1080p60) and camera control signals, up to 4 single-channel HDBaseT decoders, saving more cost and complexity for system integration.Datavideo Yangming has a complete HDBaseT solution and related equipment required for system integration.
