The 24S V1 camera has relay trigger for the camera multi-cable.

There is a Replay -to-PWM module in the camera box, It is used to convert Relay (TTL) to PWM triggering. (see below photo)

WITHOUT the Replay -to-PWM module, if user connect the shutter and GND ports directly to flight controller, then it is Relay (TTL) triggering.
