Are indoor Wi-Fi cameras safe from hackers?

Mainstream Wi-Fi cameras from established brands are reasonably safe if you use a strong password and two-factor authentication, but no internet-connected camera is hack-proof. Parents who want to eliminate that risk entirely tend to choose non-Wi-Fi baby monitors (HelloBaby, VTech, Babysense, GoodBaby) that use a closed RF link to a dedicated parent screen — a point repeatedly made by parents on r/NewParents and r/daddit.
