With the continuous development of projectors and projection screens, the home audio and video system has become more and more perfect, and for enthusiasts who are keen to pursue home theater, not only higher configuration projectors and 4k or even 6K projection image quality, They began to pursue the intellectualization and automation of home theater, so as to realize the synchronization of the projector and the projection screen

Hence the trigger!

How triggers work:

The working principle of the trigger is that when the projector is turned on, the trigger detects that there is current passing through the AC input of the projector, the trigger will automatically transmit a wireless signal to the electric projection screen, and the electric projection screen will automatically rise or fall ( It is determined according to the type of screen); when the projector is turned off, the trigger detects that there is no current passing through the AC input of the projector, and the trigger will automatically transmit the wireless model to the electric projection screen, allowing the screen to automatically drop or recover, and easily realize projection. The machine works synchronously with the projection screen, and plays the role of intelligent unmanned automatic control.

Type of trigger:

Triggers are divided into wired triggers and wireless triggers. In our daily delivery, we will give customers an experience version of the USB wireless trigger.


Note: The trial version of the Wireless Trigger may occasionally be incompatible with the projector
