Actually, I do use a video camera in addition to a sound senor recorder. I only observe the moring trials (from 11:00am to 12:00pm) and record the experiment via these devices. However, I try to stay away from the set up as much as possible to reduce stress. The only times I am near the experimental set-up is when I need to restart the Wood frog vocalization CD or when I need to check on a few small details.

For the night trials (10:00pm to 12:00am) I soley rely on these devices to record the experiment ;P.
