So, I went and got a few things to aid in my investigations. As learned in my first investigation, my camcorder doesn't do much good in the dark. So I got an infrared light that attaches to my Sony Mini-DV. I also purchased an audio recorder for EVP work. Oh, and a flashlight!
Sony HVLIRM Battery IR Light
A must-have for nightvision with a camcorder. It attaches right to the boot and is self-powered. This thing puts out some great light!
Olympus MB Digital Voice Recorder
Out of all the recorders I looked at this one stood out because the device itself plugs right into your computer with a USB connection. Most have a wire you have to keep around - not this one. It also records almost 70 hours.
