What is the functional difference between wireless video transmission and wired video transmission?

Generally speaking, there is little difference in the final function, which is generally the following aspects;

① Connection mode: Traditional wired video transmission uses ground wiring for video transmission, while wireless video transmission uses wireless channels for transmission, similar to the current WIFI wireless mode.

② Transmission objects: wired one-to-one, one-to-many and wireless one-to-one. So far, it seems that only the Skyshow series of Vision Wireless has achieved multiple transmissions and one reception, and the others are still on a single line.

③ Transmission time: wired transmission is real-time, that is, the delay is very small. There are two kinds of wireless transmission: real-time transmission and delayed transmission. Wireless real-time transmission is not really without delay, the lowest in the market is within 10ms, and delayed transmission varies according to different uses and products.

④ Transmission cost: The cost of wired transmission is much higher than that of wireless transmission. Wireless video transmission does not need time-consuming and laborious wiring, and the installation is simple. Take the Tian Yan series mentioned above as an example. Tianyan 2 has a delay, but the delay time is very short. Just add a transmitter to the camera and a receiver to the terminal, and there is no need for full-field wiring.

⑤ Advantages and differences: The price of wired transmission equipment is relatively low, and it is relatively easy to use for small venues or immobile cameras. Wireless video transmission has many application scenarios. As far as I know, the products under the brand of Vision Wireless can basically cover many fields from film and television production to commercial live broadcast and online education.
