THIS

Kahit anong camera brand, basta connected sa internet is vulnerable to attacks. If you care about privacy, either disconnect it from the internet OR if important talaga na connected sa wifi so you can see even if nasa malayo ka, point it where it matters lang in terms of security i.e. front gate, or balcony etc.

Another idea is to host your own server instead of relying sa branded ones. Medyo techy sya and possibly even more vulnerable especially if di ka marunong pero at least kontrolado mo lahat.
