If anyone has worked on multi-camera person tracking, MTMCT, Person Re-ID, retail analytics, or CCTV analytics, I would really appreciate suggestions, papers, architectures, repositories, or practical implementation advice

I’m currently developing a real-time multi-camera person tracking and re-identification system for a retail shop , and I’m facing some identity consistency issues. I would really appreciate some advice from people who have experience with Person Re-ID or Multi-Camera Multi-Target Tracking (MTMCT). My goal I have multiple CCTV cameras in a retail environment, and I want to: Detect and track multiple people in real time.
