Can the recording pen automatically record and turn off automatically?

Then I recommend you to buy Yajia A08, A09, A06, A 10, A 1 1, all of which have the functions you mentioned.

Only A06 is a dry battery, others are lithium batteries. A 1 1 one with laser light and remote steering function.

At present, the newly developed recording pens, V20, V2 1, V 18 and V22, all have the function of timing recording (automatic closing).
