Which type of recording is more efficient in saving storage space?

Event-based recording is considered the most efficient method for saving storage space because it only records footage when specific events or triggers occur, rather than recording continuously. This means that during periods of inactivity, no data is being recorded, which significantly reduces the amount of storage space needed.

In contrast, continuous recording captures every moment without interruption, leading to a large accumulation of data, regardless of whether anything significant is happening in the monitored area. Scheduled recording also generates significant data by filling specified time slots, even if not all of that time contains critical activity. Manual recording relies on the operator to start and stop recordings, which can lead to gaps in coverage and potentially waste storage if not managed carefully.

By focusing on recording only relevant events, event-based recording optimizes storage use, making it a preferred choice in environments where storage constraints are a consideration.
