Hi all, I hope I can post about this in this networking form. I have a modem and my own netgear router. I think its the R300. plugged into that router I have my media streamer (nVidia Shield) which I use to watch movies on my home theater, a Windows 11 machine which I use as my Plex server and storage of my most recent movies, and a switch. I want to get a security camera system installed on the outside of my house using an NVR and about 3-4 poe cameras. all the cameras will get plugged into the NVR. I would like to plug that NVR into my switch because i'm hoping to be able to see my camera feeds on my other Windows machine (not the one mentioned earlier). My question is, will this affect my lan and bandwidth when i'm watching movies? most of the time the cameras will be recording onto the hardrive of the NVR, but I won't be watching the feeds so I figure it won't affect my lan bandwidth. but I just want to make sure. What do you guys think? Thanks in advance.

If the cameras are directly connected to the NVR then they are independent from your home LAN. Watching the NVR would generate traffic on your LAN. But if the devices on your LAN are connected to a switch, then traffic from port 1 (NVR as an example) and port 4 (Windows PC) would not impact streaming from Netflix to a TV on port 3. Your Windows PC might become a limitation, but that is unlikely with gigabit network being the norm.
 
I don't quite follow. lets simplify it. my network right now is as it is. simply by plugging 4 cameras into the NVR and plugging that NVR into my switch or router and not watching any of the feeds, just having the cameras recording, that shouldn't change anything on my network in terms of traffic right?

Correct.
But with gigabit wired speed, it really doesn't matter. Security cameras are typically less than 10Mbit (even 8MP cameras). So 4 cameras, even at 20Mbit / camera is 80Mbit out of 1000Mbit. That amount of traffic will not be noticed.
 
but that 80Mbit won't actually go through my network unless I want to watch the feeds. we're talking about not watching any of the feeds, just having the cameras recording. the video that's being recorded should not be entering my network, it should just stay within the NVR right?

I already said you were correct. How many times do I have to say that. I am also saying, that you are worrying about NOTHING.
 
We use a Reolink camera system at work, all the cameras are inside our CNC machines. All the cameras have a network cable that runs back to the NVR box and the box has a monitor, keyboard, and mouse so you can see everything and go back and watch the recording.

The NVR box is then plugged into the local network and has a desktop app along with phone app that you can watch and monitor the cameras on. Short of running all the network cables to the cameras is a very easy system to setup and install.
 
using an NVR and about 3-4 poe cameras. all the cameras will get plugged into the NVR

Do the security cameras plug directly into the NVR or they are wifi/ethernet based? Brand and model link so no confusion here.

You could use any number of programs to see if there is network traffic. Even aside from just watching the cameras, according to brand and reputation alongside certain cloud features it could be sending traffic elsewhere which 'could' be noticed on the LAN side. Just about the only situation I would consider it being immediately obvious to the end use case would be while streaming 4K video off another device on the LAN.

Even at that, and as stated above, outside something unususal there should not be enough data transfer to notice outside something strange going on. (reputation)

I know. but I wasn't sure if you meant that where wouldn't be any traffic at all or that there would be traffic, but not enough for me to notice and lag. sorry I don't mean to be a pain. thanks for your confirmation though.
 
Apparently the IP camera IPC-T260HA-LUF/SL is plugged into a network switch/router, not directly into the NVR.

And your NVR has a maximum of incoming and outgoing 80Mbps traffic according to the spec, it's not going to affect your network at all.

Your Netgear R300 probably is RS300?

so you're saying this camera will not work at all if its plugged directly into the NVR I provided? where does it say this?

Yes, its the netgear RS300

So I never bothered to read the spec sheet for the NVR before now. It only has 1 10/100 ethernet port

So you might be able to plug 1 camera into it directly but then I don't know how you view the video.

I would look for a different NVR product this looks like garbage. 100mbps total bandwidth will have issue with a lot of cameras, depends on how much it is compressed.
 
It has a RJ45 port and IPC mean IP Camera and that means it's network based. I don't know if it has other interface.

The fact however as suggested was the NVR bandwidth is only 100Mbps no matter how many cameras attached or plug into the network.

I also read that it only has 1 network port. but I assumed that was just the network used to connect the NVR to a network. if its an 8 or 4 channel NVR, it must have 4 or 8 other network ports for the cameras to plug in, no? I was not able to find a picture of the back of this NVR for some reason.
 
OK. So it does have 8 network ports that support PoE so it can provide power and do data transmission at the same time.

But still, it uses 80Mbps only according the spec and it's not going to saturate your network and affect other devices on the network at all

It appears there are lots of different models with very similar part numbers.

I was basing my comments on the device that was linked, which is the one called nvr-108-mh-c. That one is the same unit without the 8 extra ports.

If the unit is actually nvr-108-mh-c-8p then it has 8 ports that can even power the cameras.
 
I have 2x Reolink PoE cameras.

Reolink RLC-423 (Refurbished) - 5MP PTZ PoE Security IP Camera | Reolink Official

Meet Reolink RLC-423 (Refurbished), a 5 megapixel pan tilt zoom PoE security camera for outdoor/indoor use. 4X optical zoom, night vision, motion detection, remote live view, etc.

Soon to add a 3rd.

Currently, they are plugged directly into a ReoLink HomeHub Pro. Previously, a PoE switch and then to the router.

They record directly to the Reolink hub, 24/7.
Previously, recording 24/7 directly to me QNAP NAS.

Right now, they are displaying on the HTPC monitor, and on the 3rd monitor from my main CP.


At no point in time has there been ANY impact on the network. Even with the HTPC showing both the camera videos and whatever movie I'm viewing.


This is the current traffic from my HTPC.
Doing basically nothing except for displaying the 2x cameras.
