I think it’ll be good to have a baby/pet cam is no one is home the whole day. Also a camera outside the front door too

If your helper is trust worthy you don't need it and you should also find time to monitor If you install it

Only if I have a maid to check up thru app on my kids at home

Only if I hire a helper and my child is still very young.

Possibly, we are having this debate at home at the moment

If both parents are working, i think its great to have.

Especially those kind which I can check via my App

Currently no, but have been thinking of doing so

Unless there are outsiders (Helper / Tenants)

Not within the unit until we have a child
