Well full license to blueiris is more expensive than ring cam

there are free alternatives but i only know them for linux, like Frigate, MotionEyeOS and similar. Actually you can install those on something like raspberry pi, and connect usb webcam to it. So thats another option
There is ring home cam, eg
Code
amazon.com/Ring-Battery-security-privacy-controls/dp/B0CD9LN2VK
but also competition from like xiaomi, eufy etc. You just put it whenever in your house, connect to wifi and voila, you can watch it on your phone from anywhere in the world
