Due to work needs, we need to carry out some activities as well as anchor live broadcasts. In February, BMD released a product that can convert HDMI or SDI signals output from the camera into live broadcast software-recognized network drive signals for live broadcast via a USB link. There were also similar devices before, either more expensive or inconvenient. I hope that such a niche device shared this time can help many people solve the problem of less than ideal live video.
The official website did not purchase links, we can search for Taobao. Single machine official website quotes about 4200, there is an additional switch panel, you can switch two video, there is a small LCD monitor. Only 750 yuan, very cost-effective, it is recommended that all buy this are added with it.
The body and the panel are two packages after arrival.
This is the main body without adding panels 
On the back there is SDI and HDMI input and output. By the way, there is no power cord and USB cable in the package. Need to buy it yourself
Unscrew the front plate with a screwdriver to install this.
I use a Sony A7S2 plus monitoring output all the way to do HDMI test
The screen of the current line can be displayed on the small screen. Shooting is not a screen problem. But the screen quality is also very poor. Who makes this panel so cheap, understandable. 
Just find a live assistant to test. Simply set it in the software.
Take a look at the studio's face value.
Well, real shots in live streaming. It's definitely much better than a cell phone camera.
This thing solved my big problem, but it still has some shortcomings. First of all, don’t give out data cables and power cables. Even more incredible is to add the panel, can only switch two video, other buttons, it is useless. . . . . I called customer service. The menu button audio keys are invalid, indicating that the panel is not designed specifically for this device. There is also a drawback. When switching video, audio will be stuck.
In short, the device feels more hastily and many things are not perfect, but it does solve the camera link live broadcast problem. Hope that manufacturers can update the firmware to solve these problems. We also hope that everyone will gain something after reading it. If there is a big God who can share some better solutions, it will be even more desirable. thanks for watching.
