Need recommendations for BB Blue camera for smart dog door product

I’m looking for recommendations for an inexpensive USB “spy camera” (day and IR night-vision capability) hardware that is BB Blue compatible – and includes a microphone and speaker for two-way communications.

My current smart dog door design uses a mini speaker & microphone connected to the BB Blue USB port – and an Arducam mini camera connected to the BB Blue SPI and I2C interfaces.

So, in essence, I’m trying to simplify my smart dog door design and reduce cost by getting two birds (video & audio) for the price of one (BB Blue USB port).
