Edit: Changed typo to “option 1 is much better” - thanks for catching this RickO. Also changed “Record on Event” to “Record events only”
Edit: TL;DR - Answer is #1. See https://www.wyzecam.com/forums/topic/question-for-wyze-when-using-record-on-event-when-is-%ce%bcsd-card-written-to/#post-154317
The specs for the V2 camera (that seem to have disappeared), stated that the V2 cameras had 128MB of DRAM (volatile, working memory that loses its contents when power is lost, but compared to μSD flash memory, is much faster and it does not wear out when written to).
Which of the following methods is used when “Record events only” is active?
- The one minute videos are written to dedicated RAM buffers (perhaps double buffered between two buffers, one used for even minutes and one used for odd minutes), and then processed and written to μSD Flash memory only after the buffer is closed, and only if motion was detected during the recording to RAM.
- The video always written to μSD Flash memory, and then if there was no motion detected, that file is deleted, and the storage recycled back into the "free memory".
- Something else (please specify)
