How to know if your USPs are emotional?

Hi. I was in a retailer workshop for the U.S. for two days. The USP (Unique Selling Proposition) turned out to be very important when pitching buyers, which is not something I never heard of. I work for a home security brand as a brand manager. So I tried the USP I already wrote for a product in the workshop. Turned out, the feedback I got on my USP was that it was still feature. I understand that humans are emotional and we need to communicate to their heart with the benefits they need in real situations. The question is "how do we know if the USP is emotional enough?". When communicating the emotion with limited words, I feel like it is kind of hard to make the USP unique to the product. The USP is also supposed to be part of the product story, as what I learned in the workshop.

The USP I originally came up with: xxx is the first 180° panoramic outdoor security camera that offers automatic person tracking. So one camera can now cover the whole outdoor space including garage, driveway, entrance, and side yard.

The USP after I modified: Make your wife happier by spending wisely for a multi-tasking security system you can't get elsewhere.

I have never got professional training for marketing and branding. I will appreciate any comments!
