Sure, but it has the same energy as saying it's worth having a camera in your living room recording 24/7(to the cloud) because any potential recording of burglars entering your house is worth having.

It's only worth powering those cameras up when you're going to be out of the house for a long period of time. Power them down on return.

You say that, but people actually do that.

I, for one, find it weird.

I have some cameras at home. Bought them to monitor the cats when we are away and they.. just stuck.

I use Apple’s homekit secure video thing and the cameras are only set to record when nobody is home. Otherwise they are basically powered on 24/7.

I guess it is weird but I kind of forget that they are there.

It's one thing if it's only recorded and stored locally on your machine and another if it's some private company with dubious history that records everything.
