Raspberrypi and connect an oak device to it. Then connect the microphone to the RPI.
AnamikaGupta Which can detect even smaller objects with low resolution if kept at a longer distance, can work properly in night view, or low light.
https://docs.luxonis.com/projects/hardware/en/latest/pages/articles/sensors/imx462/#imx462 is the best night vision sensor we currently support, but it's only 1080p. Likely you would need something with more MP.
AnamikaGupta It must have USB/Ethernet connectivity, low internet bandwidth
Bandwidth is not an issue unless you are streaming high res frames.
AnamikaGupta If it has auto focus capabilities then it can be changed to manual focus and vice versa
AF sensors can be manually set. FF cannot be changed at all.
