it goes with the new spy theme. It's a remote wireless camera that transmits to a hand-held video monitor. It can also be installed in the new remote control spy vehicles, so you can do surveilance and recon by driving your spy vehicle remotely and being able to see what your spy vehicle sees from the driver seat. So theoretically you can drive your spy vehicle into your sister's room and spy on her girly gossip when she has slumber parties on the weekend, lol. but it will cost you a pretty penny.
