Its not. What you are describing is 100% fineCan someone smarter than me explain why a separate, isolated switch is needed for the cameras?
Personally, I have a separate VLAN for cameras which allows for even greater control because I have my tinfoil hat on very tight
It is possible that your camera could be doing sneaky things and end up being able to talk out (This has happened, nefarious firmware is capable of changing MAC Addresses and switching IP settings, etc) however, for a simple home setup its probably not worth worrying about
To your original comment, a separate switch is 1000% never needed, the ideal situation is just having them in a separate VLAN
