Additional features and requirements
The 70mai 4K A900 Ultra includes a range of features, such as buffered emergency recording, which captures up to 3 minutes and 10 seconds before an incident and 30 seconds after. This functionality is designed to provide comprehensive coverage during unexpected events.
