"Sorry sir, if you wouldn't mind just saying that again and leaning a little bit closer to that pen on your desk, that would be great."
Bill is able to transform an ordinary ballpoint pen into a monitoring device that is inconspicuous enough to blend in to most settings, but advanced enough to allow 360 degree surveillance as well as audio capture.
Bill can leave these spy pens behind in a location, and will be able to see through them as if he was standing at their location. The feed is also uploaded to an app on his phone which stores a recording of anything that it picked up.
Spend an Action and Exert your Mind to place a Ward. You may have at most 3 wards running concurrently, and they must be attached to a ballpoint pen, which can be placed in a location or moved around. You can hear and see through the Ward as though you were standing at its location, but can only monitor it through an app on your phone.
The Ward requires your full attention to monitor. It cannot be detected by mundane means, but can be destroyed either on accident or if someone knows what they are looking for.
