Possible Bandwidth bottleneck?

[SignalRaptor]

I'm trying to find a way to connect 7 sets of devices at medium distance. It's outdoor equipment so it's contained in conduit and ran up to a central location.
On one end is a enclosure containing a camera cluster, on the other is a box containing devices to receive information from the cameras. Previously all these devices were in separate enclosures so they had to be split off and ran to each individual camera, resulting in running 7 cat6 cables through the conduit.
With this new setup, I wonder if I can run all these devices to a single switch, run a single cat6a cable up into the new enclosure where I have another switch, and then split off into the other cameras. All these cameras are on different subnets. They are 12 MP cameras. I don't want to say more because this is for my job and I don't know how much i'm allowed to disclose. It is imperative that the data move as quickly as possible, if something is slowed down for more than a few seconds it will cause issues.

TL;DR can i safely consolidate 7 12 MP cameras that were on their own cat6 cables down to one cat6 cable between two 8 port switches, or will I run into bandwidth slowdowns?

Look at the bandwidth they're actually using to work out if a single connection is sufficient or not.

 

I'm not that great at networking but since you mentioned different subnets, depending on how it was set up when it was ran with separate cables, if you did move it to a single switch you may or may not need a managed switch and to also configure the other end.

what is the bitrate these devices are using?

 

Most cameras won't max out 100m, so a single gig link will likely be more than plenty.

If this is for your job, I'd ask your team instead of people online.

Currently treading new ground, the team I have is 3 of us.

Upon doing some calculations on my end I think i should be fine. These cameras capture raws, and send uncompressed images at 4096 px × 3000 at a max rate of 8 fps (will not be running at this speed). Doing some basic math, 12 MP is 12,000,000 pixels, at 12 bits per pixel, that's 144 Mb per second, times 7. My subpar math comes out to 1008 Mbps which is way too close, and I just want to check with people who are smarter than I to see if this math is accurate.

Did you ask the camera manufacture what the bitrate of the cameras are?

 

What network connection and speed to the cameras have?

 

Cameras are normally compressed, so its possible to see that bitrate, but I'd guess its more like 10Mmbit from the security cameras I've used.

These aren't for surveillance. they take still images of objects in motion using a radar for triggers, so bitrate is negligible. I ran some tests on my end and was able to see that they run at about 112 MB/s at their max frame rate. with all the cameras attached this is going to be about 9 Gbps, which is really pushing the limits of cat6a, requires a 8 port 10 gigabit switch, and frankly i no longer think this is worth the risk if one of any of the devices fault. I'll just run individual cables.

tbh i do  cheap fiber then. out door rated stuff.

bet a bit  of a pain to set up. but it would be worth it for this odd use case.

i get the bw issue now ref the still  high rez out door camera ref.
