These accessories provide audio and video recording capabilities for simple monitoring (for safety purposes, for example) or as an additional source of behavioral data.  In addition, we are able to provide a two-way audio communication channel that is always on for the subject and with a push-to-talk mic for the experimenter.  Don’t underestimate the difficulty of choosing the right combination of cables and accessories to create a convenient audio and video monitoring, communication and stimulation environment.  Tell us what you are trying to accomplish, and we can configure a kit for you to meet your requirements without any excess components.
