The solution to detect current surges and activate the alarm is the one used by more than 90% of manufacturers. In theory it is useful, but in practice I know it is of little use. People already know that and when they try to attack the machine, the alarm goes off and they quickly shut down the...

What you say is true, here everyone protects their machines by putting metal meshes on the displays, aluminum sheets on the pcb (especially the controllers) and some connect the power supply cord to ground. That is another big problem. A lot...

That does not usually happen because the machines are installed in small businesses that are always supervised by people and contain very little money inside, it is not worth going to break a machine to steal money. However, many people carry spark plugs or devices that can burn/alter components...

It is a very economical and basic machine made for low-income places, so the cabinet is made of wood and at most aluminum sheets or an aluminum mesh can be added. But my work is not the cabinet, but the PCB. So I want to see ways to protect the components, especially the shift registers because...
