Mic setup. If you are thinking of installing an external microphone on this SD59225H-UNI, there are multiple ways to go about it for signal and power.
For my test rig, I have it on my home network, running off the power brick. I bought these outdoor mics from Ryan's recommendation.

For now, I am just test powering the microphone with these over a
Cat5 cable.

That same power supply is split 3 ways and powering my PIR sensors as well. With 5 amps available, 3x - 75 foot runs should be no problem. These inexpensive connectors make the power connections easy.

To attach this mic, I bought these as this camera doesn't come with an RCA plug like the HDBW5231R-Z.

While awaiting their arrival, I just hacked an old stereo connector and used the above 5.5mm/2.1mm connector as a temp solution.

As others have stated, these mics are super sensitive and pick up the faintest sounds. Line in level is reduced from 50% (default) to 20% and they still grab every sound. My testing is nearly complete. I now have the mic and two PIR sensors rigged to alarms/PTZ presets and it works stellar. The auto tracking is pretty great as well.

Sorry if this is a confusing mess of wires. I just used Cat5 cable for everything. One pair in to the NC ports of the PIR, and one pair attached to the 12v power supply. Again, the 12V is shared 3 ways.
