MOMCOZY BM04 Smart Baby Monitor (Free C&C)

Have tried & returned many baby monitors, this one hits the brief. I need an additional camera (you can add up to 4), and stumbled across this deal.
Does not come with a forced subscription like most monitors. You have the option to save videos to their cloud (paid monthly), or just put a Micro SD card in (one off cost)
Full HD baby monitoring system designed to give parents a clear, reliable view of their child. It features a 1080p HD camera, night vision, two-way audio, cry detection alerts, and a wide 350 viewing angle with up to 4x digital zoom.
