(Spy Monkey were great - fast and easy to communicate with)
Camera itself is sold and decent quality. Set up is a bit convoluted given the camera insists on a particular IP address (192.168.1.108) - bit of a pain if you're not on that subnet etc. Would be much better if they were set to DHCP by default.
Other than that setup is reasonably painless and these work well with Frigate NVR.
