Looking for recommendations for a network switch with POE that's able to isolate a camera connected to it from the internet

[Gazz292]

I want to get a POE camera or 2, they will be connected via cable to the router / switch (hence needing POE) the cameras i'm looking at are 2.5K resolution.

As i've run out of ports on the bt infinity router i'll need to buy a network switch, i guess a gigabit switch with 8 ports will be about right for me (10 ports in total over the infinity smart hub 2 and new switch)
I only really want to view the camera's from within the house (they are to allow me to watch my 3D printers for things like filament tangles, failing prints etc when i am in another room)
A review of some cameras mentions they keep trying to 'phone home' and the need to filter them at the firewall due to that.

This is where things go over my head and i'm not sure how to do things like that, but i could look it up and follow instructions etc... but i'm thinking, would it be easier if i could restrict the cameras ability to see / access the internet? and if i could do that then i'd also like to do the same for the 3D printers network connections, there's no need for them to be accessible / visible on the internet.

When looking at POE switches i noticed there's 'easy smart' / managed versions of some of them, would one of these switches be what i'd want to get to be able to set things up so that the camera's and printers can only be seen on the home network and not the internet?

Budget isn't much, £50 to £75

Are you planning to be able to view the camera feeds only on devices directly connected to the switch (I.e. not via a port on the BT router or over WiFi)?

The way i have things now:
The BT smart hub 2 (i think it is) is in the room where the phone line comes in, which is also where the 3D printers live, and where the camera(s) i want to get will live.
The wifi from the BT hub is used by my dad's phone and kindle, then ethernet cables go to dad's desktop PC, the inkjet printer and the smart tv in the living room.

Then the last ethernet port on the smart hub has a 25 meter long cat6 cable that goes to the other side of the house.. where i spend most of my time.
That cable is plugged into a Honor router 3's WAN port.

The wifi for that router is a seperate one to the BT one, and to that i connect my laptop, phone, android tablets etc via wifi (and a tv, playstation and desktop pc to the remaining lan ports)

I'd need to view the camera's over the honor router's wifi network, not over the BT hub's wifi network.

:

As others have mentioned, i am likely overthinking this, just worrying about someone gaining access to the camera's, seeing they are looking at 3D printers and hacking into the 3D printers to do something like set the hotend to 300 degrees C and drive it into the plastic of the half finished print to try and start a fire.

i know the solution to that is to not connect the network to the printers and transfer G-code files via the usb stick, but the idea of the camera's is so i can check on the print progress every now and then whilst i'm doing other things, and if i see something going wrong i can pause the print and go and walk to the other end of the house and check it out in person.



Perhaps the solution is to just use a basic non managed network switch with POE ports, and set up the firewall properly on the BT home hub router?

dang, i'm sure i'd sent a reply a month ago, sorry for going silent.

i've still got nowhere with a camera / NVR setup, mostly because i've been busy working on the new room that is housing the 3D printer(s)
now that i've done an upgrade on my Prusa MK3 to make it a MK3.5, i know a little more about what i need with a camera setup (still waiting on delivery of the other printer (Prusa XL)

The software used to send the g-code files to the printers and control them is 'Prusa Connect' and it includes a basic camera viewer in it,
This viewer uses RTSP, and grabs a still shot from a linked camera every 10 seconds to show on the Prusa Connect screen, which is accessed via a 'secure' webpage... there is a thing called Prusa Link which runs locally on the home network, but it's very basic compared to connect, and i suspect it grabs the camera image(s) via the internet anyway.

All i know is that RTSP means Real Time Streaming Protocol, and it's something do do with sending video images over the internet, so i am unsure if this is going to be insecure to do so.




What i am thinking i want to do,

I'd have at least 2 small fixed cameras that will be mounted, one on each of the printers, looking directly at the nozzle,
Then either a few more fixed cameras looking at the filament spools, or a PTZ camera mounted on the ceiling overlooking everything, i prefer the PTZ idea as then i can move that camera to overlook both printers, and zoom in to look closer at any potential issues (filament tangles, running low on filament etc)

These cameras i'd connect to a NVR as @WJA96 recommended, that'd sort out powering them too i believe.
i've no need for recording the images atm... but i could see me perhaps adding more cameras at a later date to maybe look in the bird nesting boxes in the garden, and maybe watch over the home workshop etc.

The NVR should allow me to view the live stream of the camera's on a web page on my laptop, connecting to an IP address that is on my home network only.

Then i'd need to do this RTSP thing and get a snapshot from each camera sent to either Prusa link or Prusa Connect,

Most of the time i'd have the Prusa connect / link page showing on a tab in chrome, or on an android tablet that i have mounted next to my laptops screen,
This will allow me to keep an overview of the print status and data like temperatures etc, and i could also see the 10 second camera snapshots to spot something going wrong (you can add multiple camera RTSP 'streams' to the Prusa Connect page i believe)

So if i see something not right on the snapshot images, i can then switch to the camera livestream tab and view the cameras in real time, move the PTZ one etc. then pause the print via Prusa connect / link and make my way to the other end of the house to investigate in person.




i believe that this RTSP thing throws a spanner in the works of keeping the camera streams local?

And it may not be as simple as starting off with buying a cheap NVR and adding things to it as needed?

would you be able to recommend a NVR that i should look at, with say 8 inputs for POE cameras, able to add a HDD later, and can do this RTSP thing?

Gotya,
all these things go over my head, i'd never heard of RTSP until i got the prusa connect thing going for my 'new' 3D printer,
