Clean attendance data from NVR logs

Engineered Python scripts to interface with Hikvision NVR systems for fetching raw logs, and designed logic filters to clean noisy camera data (duplicate records/non-attendance) for accurate HR tracking.

Problem

Raw attendance logs from Hikvision NVR cameras were noisy, with duplicate records and non-attendance events.

Approach

Python scripts pull raw logs from Hikvision NVR systems
Logic filters remove duplicate records and non-attendance events
Cleaned data loaded into a database for HR attendance analytics
