Is it possible to leave a smartphone (turned on, as a security camera) hanging all day long on the stream or could it be dangerous in the long run?

So I would like to stop my old smartphone time for video surveillance so from 6 o'clock in the morning to 18 o'clock in the evening about about the whole time left on, so I just on the Internet on the camera now and then can access, but I wonder if that because of the power supply could possibly be questionable (since I have often heard times that these sometimes can start to burn) and well if I then just just the whole day is not in the house, that would not be so nice…

Although it was actually always just so cheap charger to which it was in the headlines (I think from China) but it is synonymous yes so synonymous just the brands, such as Huawei, etc. So synonymous in China make… 2tens the power supply is yes do not I think I'm also designed to be in service for so long (pretending if you do that every day now?)

But now briefly and concisely to the question:

Would you consider leaving an older Huawei smartphone on the power supply all day (turned on)

Or is not at all necessary if the display is switched off, the camera and WLAN however are active? I think so, right?

Which app would you access on the way?
In itself, I think the idea is not bad😎😎

If it really should be simple. Private Youtube stream

So I have misused an old tablet as an alarm clock, it is already a 3/4 year with the display turned on, is not good only for the battery.

Cool

Cctv IP camera Alfred zbsp. Is the app (there are of course others, but I'll try this first)
