The problem: I have an old Lorex DVR 4K Ultra HD with four camera inputs and a single audio input. I'd like to add a microphone to my security system, though I'm not using it as a "Security" system but rather more of a YouTube studio for making video's. I'm still waiting to hear from Lorex but looking through their stores I don't see an audio system that can plug and play. It's looking like I will need to bodge together something. Don't know what would be better; Dynamic mic or Electret mic - or other. Any ideas?
If I end up building my own I have no idea what the impedance of the input is or if it accepts a preamplified source or if it takes a cold mic. At present I think somewhere in my vast collection of junk-stuff I might have an electret mic but I don't know if I can find it anytime this year. It's already late in this year, it's already past the middle of January. I DO have an old mic from a computer, the mic plugs into the input port but the last time I tried using it success was lacking. Also have a mic from a car audio system that included hands free bluetooth cell phone service. I don't know if that will work. Haven't tried anything yet. Better to have an idea than to blindly stumble forward and damage something.
