Highly Efficient and Optimized Methodology to Store Video Data by Using the Hybrid Approach

Abstract

In this digital world, Video and Audio (unstructured) data have increased exponentially over the past decade. CCTV surveillance used as a method of maintaining the records for audit to provide Safety and Security as well as Legal, Insurance, Financial, and Health. Storage of video data made safe and secure to the society and organization. However, it is a challenge, in storing the different formats of video data and utilization of space is a constraint, time limit on data storage as well, and not easy to retrieve the data based on the event. Currently, the CCTV transmitted video data is stored in the database server without any changes in the conventional approach. In our hypothesis efficient data stored for an extended period for, further processing. Proposed Hybrid solution with three stages to store the video data in the Specific system.1. Removing the redundant frames by using an efficient background subtraction algorithm 2. Threshold/Entropy approach on Keyframe Extraction and 3. FFmpeg module to compress the file. Executed our solution on a real-time CCTV system in a retail store consists of three cameras to calculate the reduction percentage and improvement of the storage time limit in the specific system. Effectively retrieving Videos from the database without any loss at any point in time. Storage space reduced by 40%, so that increases the period from 60 days to 90 days and it is easy to retrieval the data based on the date and time.
