Can I connect an active microphone to an IP camera?

Question

JavaScript

Greetings. There is an IP camera Beward BD4330DS powered only by PoE.
There is a "Shoroh-7" microphone with a power supply of 7-13 V.
A microphone with 2 leads is installed on the camera itself.
I want to do this: take power from the camera board for "Shoroh-7" and connect it instead of the native one.
Will it work?
Thank you.

Answer 1

It looks like it should work like this:

var f=function qwe(){var x=10; return x}
console.log(f);

Another option is to globally override console.log();

Answer 2

Read about scopes and contexts in JavaScript (they are not the same thing).
https://learn.javascript.ru/functions-closures - scopes
javascript.ru/ecma/part10 - contexts
In short, the function forms its scope (scope) when you declare a variable in this scope (inside the function), then it will be visible only inside this function (it closes inside this function). If you need to get the value of x , then you need to either declare it outside the function, or return it as the result of the function execution.
I will not write examples, as there are above.

Answer 3

Yes, if you find the necessary food - most likely there will be only 3.3 V.
