CCTV + AI business usecases validation for our platform

Hi all , we are currently a team of two , with periodical help from outside professional network have developed a platform to get cctv feed to cloud servers and analyze said video content and alert users through phone call , sms and whatsapp etc

We have worked on a usecase for starters and solving or perfecting the data science model we developed etc

Also looking to try our foot with other business usecases

I am wondering as to how to discover business usecase that owners would love to pay us as a SaaS product

1). we are thinking of garage car parts theft detection at night time and said alert system , all in real time leveraging existing cctv camera that businesses have

2). Fire detection and alert system with existing CCTV cameras that owners have

Is there any market or need for these above solutions .
