If I use an sd card why are my clips on the app only 12 seconds? Also uv light question

I thought the point on the sd card is so you can have continuous recording. I look in the app under events and all my clips are still 12 seconds.

I am also wanting to get a uv light to give better night time footage for my cameras, any recommendations?

The Events are stored in the cloud, and are 12 seconds. If you have selected continuous recording, to the SD card, you view that in the app by seeing “view playback”. There you will find the whole recording,
