Would something like OPNsense run on this to provide 16 ports of POE or 8 ports of POE+ at 100mbps?

The POE has different configurations available, in general it allows 120 watts per 8 ports. There are some suggested layouts in the user manual.

I noticed in the downloads that only Windows drivers were given, and that it has TPM 2.0 and UEFI, so Windows 11 spec. I hope Linux will be able to "just work" for building something like Frigate.

I'm planning a 256gb ssd for system, and a pair of 1tb spinning drives for storage. This plan because I have them on hand and not going to buy something until I figure out what it can do. I'll have to think about what/how to make a TPU work, the m.2 slot does not look like it will support the Hailo-8, the slot doesn't even list USB. And at a 2242 not a drive that I have on hand to use for system.

It does list an EMMC, I hope it is on a standard connector, that might be an option for system drive too. Lower power and more simple if your use case supports this method of operation.

The block diagram indicates that the POE switch is connected to an i211 PHY which is supported by OPNSense, so it should show up as 3rd interface.

anyone have a teardown of one of these? would be curious as to what the internals look like

 

[Bbolt]

The User manual has some internal pictures and a diagram of the jumpers/connectors. 2 DDR4 SODIMM slots, etc. Linked here: 10.19MB

More info than im used to finding, especially for cheap homelab gear.

 

[MB-Dmz]

Has anyone yet found the emmc module/connector? I'm beginning to think it would be a factory addon.

 

[Greg_E]

I'm guessing the emmc is soldered on the back side, and since it's optional no way to tell if all the glue chips are in place.

The manual is surprisingly detailed.

My order says payment accepted and will ship soon, hoping soon is sooner than later and fast shipping. Would be great if the brackets were included but I think I have some ears I can modify for rack mount.

I think Debian 13 with Frigate will be the first thing, though throwing OPNsense on it might be fun too, just to see if it really acts like a 10/100 switch on those ports. Mine will only be 8gb, I have a small pile of 4gb modules here from stock HP T740 computers I upgraded.

[edit] the drivers are a hot mess of zip file in a zip file in a zip file, just a warning for those wanting to try Windows.

Might also be good for home assistant if you can decouple the 54v supply to save wattage. Could always hack in a 12v supply for the rest of the board, but that brings the cost up to similar devices.

Or just run both on this one device if it looks like it can handle everything. Might be another avenue to run down in testing.

Too bad the USB Coral TPU is so expensive, I'm seeing them for $110-$200 these days, only 4 tops where the Hailo-8 is 26 tops (not sure about Hailo-10). No USB for the Hailo devices unless you have USB 4 or Thunderbolt 3/4.

 

[MB-Dmz]

i picked up a coral usb ages ago when they were under $50. It worked fine in frigate for 4 1080p cameras, but i probably wouldn't do it at today's prices. I'd try using the OpenVino first and see if it can handle your workload on cpu only.

 

[Greg_E]

Been reading up on HA and Frigate integration, with the latest HA kernel the OpenVino should work. So I think I'm going to start by getting HA running and then get Frigate integrated. Ultimately I need 6 to 8 cameras for home, all of them are 2.5k wide and not sure if they have sub streams (I hope so). I also don't remember how many watts each camera is, many have lights that can come on with a detection, all of them have IR illuminators too.

I may also rebuild the Frigate machine I'm currently working on to do the same, that one had an nvme slot so a Hailo-8 is installed.

 

[MB-Dmz]

It would be a pleasant surprise to find a 32GB emmc preinstalled. Good place to loose some config backups.

Most of the cameras I've played with (at least the ones with rtsp support) can handle 2-3 rtsp streams without much sweat, even if not documented. The bottleneck being the camera's encoder. Speaking generically, Axis and hikvision 180 cameras kept up with 3+ streams on 264 and 265, but the equivalent arecont couldnt do 1x 265 without dropping frames. 5fps 800x600 in 264 for inferencing should be a safe bet for modern systems.

Our axis outdoor cameras with IR illumination can hit 20w+ at boot up, but usually idle at 6-10w, indoor cameras usually 3-5w idle. The big honking ptz's can chug 90-120w with their internal heater and overbuilt servos.

My last frigate server was a seeed re-server that somehow cooked its ram. Lots of expansion with 3x m.2 (x4, x2 and wifi with pcie lanes) plus an inconveniently placed x4 slot. Great little server, except for the airflow problems.

For BlueIris on windows, the cameras would have to be on their own subnet with the windows install correct? They wouldnt be available to the rest of the network?

 

[MB-Dmz]

Disclaimer: I've never worked with BlueIris and have no direct experience.
It is industry best practice to separate your cameras into their own network. IP cameras usually have poor security, and vulnerabilities regularly go unaddressed for years if they're patched at all (for a number of reasons).

I don't know if any recording software requires segmentation, you can have them on the same network as all your clients and servers, but that is not a good idea.
If you have the means to vlan it, you should.
Otherwise set it up on it's own subnet.

I got mine delivered today, a couple of quick notes:

Hardware:

• Has anyone yet found the emmc module/connector? I'm beginning to think it would be a factory addon.

  Unfortunately, no header, you can see the empty footprint here. I'm sure you could solder an EMMC on, but I don't have the skills or equipment to do so.
  
• The cooling fans are quite annoying to be in the same room as. There's two 40mm fans, a chassis one controllable in the BIOS, and a louder one in the power supply. I'm thinking about soldering in the second fan header and printing a duct to use a larger but quieter 60mm slim fan inside the chassis.
  
  
• Rack mount ears are not included. I'm thinking about getting some manufactured, I ought to learn sheet metal CAD at some point and this should be very easy to do.

Software

• The switched interfaces seem to 'just work'--I was able to pass traffic over them in stock Ubuntu 25.10
  
  I'm thinking of using my unit for Frigate, I just need to figure out a DHCP server on the PoE ports.

 

[Greg_E]

Run dnsmasq on the host OS and configure dhcp and dns, there are alternates you can run.

Sad to learn the fans are loud, that's going to limit what I do.

In theory mine should be here tomorrow. I have 8gb, a 256gb ssd, and a pair of 500gb spinning disks waiting.

 

[Squeegee4943]

It's not actually incredibly loud--it's about on par with a stock Brocade ICX6450 or ICX7250. Still, it's too much for me to work or sleep in the same room as.

 

[Greg_E]

I wonder if all the glue components for the emmc are present and what kind of module we would need. Looks more like a bare chip outline than a module. Can get my hands on a hot air station big enough to handle this, I'll have to look around.

I wonder how much air this really needs, could we just put in slower fans and have enough volume to handle the heat? Power supply might be the only place where this fails.

Thinking the same thing, I've got a set of arctic s4028-6k on order to replace the stock fans. Never used them but I've heard good things. I'm not above drilling a big hole and slapping on a 120mm fan

Bummer about the emmc, but it was expected. I'll probably just put a USB in and call it a day. Been using a USB header -> usb nvme -> 16gb optane for a few years and it's been solid.

 

[Greg_E]

If there is room in the case for a quiet 120mm, a big hole and wire grate could go a long way to quiet.

I'll be interested in the results of the Arctic fans. In theory I'm going to use this for my home camera system, so it needs to be quiet, work with Frigate, hopefully have some AI recognition functions, and eventually work with home assistant.
