I recently bought a outdoor security camera from a small brand to monitor the corridor leading to my front door for strangers, and it is necessary for my home security. I have it connected to home WIFI, and uses cloud-based video storage on vendor app. However, it does sometimes make me feel a little bit insecure if I should fully trust it on my main network as it sits right at the edge of privacy/security. What are your thoughts, thanks.

I understand that password managers and 2FA are probably more important than most network tweaks, but getting my family to change habits is hard. I can improve my own network security as I am more cautious when browsing the internet, but shared accounts, streaming accounts, school logins, and a lot more from my family members are messier. I need some advices from people managing family cybersecurity that would work, thanks!

I’m realizing that despite my router being around 3 meters away from my laptop with no walls in between, when I watch Youtube or play online games, there would always be annoying things like video stuttering or ping spikes for games even though my internet is supposed to be high speed fiber network. It's not like there are many devices using the internet at the same time as well.
Before buying more hardware, upgrading my internet plan or changing advanced settings, I’m wondering if there are some basic changes or fixes that can make my home wifi more reliable, thanks

With my current mobile carrier, my phone will have really weak signal when I go out to some places (Costco, mountain lounge etc.), and mobile data will not work despite showing 5G icon. If I want to log on my personal accounts or banking apps, but my only option is to connect to a public free wifi, what are some realistic approaches I can use to keep my personal information and privacy secured, thanks.

Currently, I am thinking of improving my home network setup for privacy and gaming. For myself, I play MOBA games a lot on my computer where gaming latency matters that could affects my performance, and sometimes I need to work from home. There are also tenants and my family members living at the house. What are some network setup advices I can use to balance between network privacy and my gaming, thanks.
