another solution here is Raspberry Pi zerow or rpi3 or any (zerow+cam = cheapest option)
all you need is to install motioneyeos https://github.com/ccrisan/motioneyeos/wiki/Supported-Devices
after you connect to you network with it , just open IP asigned by dhcp for you
log in username admin password empty
few steps to setup fast network cam
after set fast network cam hit Apply button
copy url displayed in step 5
fill in DWC
and you get at the end
hope this helps someone
