Looks interesting, did U do real life testing ?
Idea: add a nice photo that’s in focus, without glare, supported on a nice surface

It works very well. Sold a few with no problems.
Very low RDSon mosfets.
Cheap camera so cant do much about that.
Mono or Stereo ? Size ?
Mono pcb.
10cm by 10cm
Uses a microcontroller.
Four second power up delay then if any DC for 250mS it shuts off relay.
DC protect pcb 10cm by 10cm with power up delay.
Uses a solid state relay for long life and less distortion.
230VAC mains powered only.
£14-99 each. p+p is £3-99 to uk and £10-99 to rest of world.
