Multiple Coral TPU?

[David Pfeffer]

I'm very close to the limits of the hardware and often get System Busy messages. I have added a TPU and it helped a lot, but, then I added two more cameras. :grin:

Does Camect have support for multiple TPUs? Will that further expand the processing power? If not, will that be supported in the future?

I would think you are pressing the limits of the camect and not the coral.   Do you know your coral is stressed?  because I doubt it is the coral stressing but rather the main camect box.   

Just my 2 cents.

By "system busy" do you mean the message below the display of the cameras, or do you mean "Camect Home is Busy" in one or more camera windows when trying to view live? 

If it's the former, are you still getting it after the update yesterday? 

If it's the latter, you may be at or near the limits of what your device can do in terms of video encoding and decoding. The Coral TPU only helps with the AI processing, not video processing, i.e. it allows you to handle larger amounts of movement on the cameras you have. That's why we don't claim that you can do more than 24MP even if you have a Coral, although we do have some people with more who appear to be happy with the results -- It depends on your use case, mainly. 

What frame rates do you have your cameras set to? Most cameras come set to do 25-30fps by default, but many people are happy with 15fps or even 10fps for security use cases. We don't support adjusting frame rates via the Camect UI though -- you'll have to connect to each camera's web interface to change frame rate.

Arup and I have differing opinions on some of this. If the camect device is running out of CPU cycles, I am not sure what you can do except to add another camect. If you have plenty of CPU cycles and are seeing network issues, you can try adding a second ethernet adapter. I have mine setup this way. The cameras are all on their own network and isolated with the internal network interface of the camect. Then I have a USB interface for everything on the outside - everything except the cameras. This has worked very well for me. There are some complex issues that can arise with networking performance and interfaces. Having 2 interfaces helps limit these issues.

Grover, could you expand on this a little more? I use mostly Wyze cameras and one IP camera.  They are all wireless and I believe that with all my other wireless home control devices, the 2.4g network is overloaded.  Are you saying that all your cameras and Camect are on a different network and then, somehow, interfaced with the main network.  I need to mitigate the amount of traffic on my wireless network. I only have one internet cable modem for output to the real world and it has enough bandwidth, but the internal network, I feel, is congested.  It would be nice to segregate the cameras from the rest of the network. How do you merge the two internal networks with the outside world?

Thanks, Carl,

Personally, I put all the cameras on their own PoE switch, which also connects to the Camect box. That switch has a GigE uplink to the rest of my network - so, there’s only traffic from the Camect when someone’s viewing it.

But I’m all GigE, here - even my internet connection is gigabit fiber.
