So, that is why I thought of using the MythTV. I am currently using camera as a security camera which should record any authorized/unauthorized RFID tag.

The record now command is press the R key while watching live TV. If
you are wanting a way to watch the videos and manage them then I guess
mythTV is better for you than developing a specific app for it. Or
using the cat command line.

Give pressing R in code a shot and let us know how it goes.
