been a few years since we introduced our first wireless video transmission systems, from the old 0-latency
Cosmo line to the new Mars series. In order to better design our video transmission products for your use
scenarios, we created this survey program.
If you use one of our wireless video transmission systems, we invite you to complete the survey. The survey will remain open until 24:00 on April 7, 2023, GMT +8, and we will select 70 people to give out coupons for purchasing ANY new product Hollyland releases in 2023!
