What do you mean by a "power drop"? Was there an effect you observed (e.g. lights flickering in your home) beyond what happened to Camect?
It is true that the device may turn off and stay off if the output from the power supply drops too low without power failing completely. In the event of a sudden power loss that doesn't include a period of power fluctuation it's supposed to power back on when power is restored. (You can test it by pulling the plug and re-inserting.)
If you own a UPS, the easiest thng may be to plug the Camect into the UPS.
If not, you might be able to increase the resistance to having this happen by using a more powerful power supply. We know at least one person having power supply issues who switched to
this one (and apparently uses these regularly in other projects, and says it has been pretty reliable for him). The only caveat about that power supply is that the barrel is a little short for some Camect units. You may need to trim off about 1mm of the plastic connector using an exacto knife. I tested one of these (just to see it myself before recommending it to anyone else) and I can confirm it works fine after trimming it.
