Programmer trying to make things

[ccinterod02]

Hello everybody

I am a programmer who works a lot with networks and I am trying to get into this world of connecting things, I have theoretical experience but quite little practice frankly.
I have been commissioned to make an installation with 3 or 4 ip cameras (I guess I will use dahua 50-80 € per camera), all the home automation (with home assistant), an alarm (with wired ajax) and wifi mesh (no idea what gadgets I will use).

For the cameras I was planning to use some dockerized recording software on a HP EliteDesk i5 which will run a lot more services.
In my head I was planning to use a switch that can power the cameras (PoE) and make 3 vlan: cameras, wifi and the rest. All boxed in a 19'' rack with fans.

It is my first installation of this type, so I don't have anything to compare. Am I complicating things? Am I going to saturate the network? Do I really need a configurable switch for so few cameras? I don't know, that's why I come to this forum in search of wisdom.

I really appreciate any advice.

Welcome to IPCT!

Save some time and money by running Blue Iris VMS on that HP PC, hopefully one that meets these specs.
Install Windows, Blue Iris and BI's "db" folder on a SSD; perform a "clean" install of Windows using the MS Media Creation Tool from a USB flash drive.
Optimize BI's performance and use sub streams.
Send BI's videos to a spinning HDD, preferably one rated for video surveillance, like a WD Purple or equivalent.

Limit IP camera access to the Internet either using a managed switch and VLANs or do so with 2 NIC's, one for cameras and one for the BI server to access Internet, such as in this schema:
