Eufy 2K doorbell Live view problem

I am using an iPad as a display of doorbell live view under guided access function with eufy app.
Here is the problem. when the bell rung, the iPad shown the live view automatically and It is great. But it won’t turn off after a long period of time and keep draining the doorbell battery until I turn it off manually.
Can you put a time restriction option on the door bell to avoid such issue?
