Multi-camera Multi-object tracking (MTMC) surpasses conventional single-camera tracking by enabling seamless object tracking across multiple camera views. This capability is critical for security systems and improving situational awareness in various environments. This paper proposes a novel MTMC framework designed for online operation. The framework employs a three-stage pipeline: Multi-object Tracking (MOT) Multi-target Multi-camera Tracking (MTMC) and Cross Interval Synchronization (CIS). In the MOT stage ReID features are extracted and localized tracklets are created. MTMC links these tracklets across cameras using spatial-temporal constraints and constraint hierarchical clustering with anchor features for improved inter-camera association. Finally CIS ensures the temporal coherence of tracklets across time intervals. The proposed framework achieves robust tracking performance validated on the challenging 2024 AI City Challenge with a HOTA score of 51.0556% ranking sixth.
