How To Choose Good Wireless Video Transmission Device?

Oct 11, 2022

Three basic aspects following deserve to be considered in terms of choosing wireless video transmission devices.

  1. Decide connected equipment

First of all, it is necessary to figure out what video equipment you use as input source and output destination. Some kits have SDI or HDMI inputs outputs or both. You could choose one video transmission system with corresponding interfaces with your devices.

  1. Consider transmission distance

Wireless video system has its own transmission distance which can be affected by actual shooting distance and obstructions. Thus, you may need to know the needed transmission distance of your video and how many obstacles may exist between the transmitter and receiver beforehand. The range of video transmission can be divided into line of sight and non line of sight. For one wireless video transmission system, it supports to transmit longer distance in line of sight than non line of sight because obstructions will shorten the transmission distance significantly. So have a whole analysis of the shooting environment before you get a wireless transmission device. For example, if you are going to send HDMI video to backstage or spectator seats, a mid-long-range HDMI transmission system could be an ideal partner.

  1. Set acceptable delay time

The latency in wireless transmission of video may affect your work a lot. It is better to learn about how much latency the transmission system produce and predict how much effects it could make to your video. If the picture and audio are not in sync or other sync problems come up, the quality of video would be decreased a lot. The lower latency you desire, the higher-quality system you may need.
