Why so many people have a special fondness for observing animals? Are there any other imaging products worth investing in for development?

  Maslow believed that human needs can be divided into five or seven levels, with physiological, safety, social, esteem, and self actualization levels progressing in sequence.

The demands at different levels are interdependent, and even after the development of high-level demands, low-level demands still exist, but their impact on behavior weakens

 On some crowdfunding platforms in the market, a product raised 4.2 million euros on the foreign crowdfunding platform KICKSTARTER's website. Subsequently, Amazon, mainstream American supermarkets BEST BUY, Sam's Club, QVC, Lowe's, and others have all launched such products. The function is to observe bird activities through mobile phones, and different birds can be identified through algorithms and shared on social media in a timely manner. It has to be said that this type of product is really amazing. What human needs does this bird watching device meet?
