The big advantage is the Homekit support if you are in the Apple ecosystem.
I am using eufy Indoor Cam 2K Pan and Tilt version outdoors for a year (but under shed). and going to replace it by this non-Pan/Tilt version as it without movement parts then may not be easily affected by dust. I just bought this model for $75.99 at JB Hi-Fi yesterday and then found this deal just after my order was made :-(
Both Pan/Tilt and non-Pan/Tilt versions have the same specs. but the non-Pan/Tilt version will have less power consumption. (5V/1A vs 5V/1.5A)
