Internal sync is a method where a camera or video device uses its own internal clock to manage signal timing. This ensures that the device produces a stable video output without relying on external synchronization.
For example, standalone surveillance cameras often use internal sync to maintain consistent video signals. This is useful in small systems where multiple devices donāt need to be precisely synchronized.
While internal sync is simple and effective, larger systems may require external sync for frame alignment across multiple cameras. As a result, users should choose based on system size and needs.
By using internal sync, devices operate independently while maintaining signal stability.
