There are several wireless pinhole cameras available in the market these days. They are all small enough to be concealed but they differ in prices. The more expensive the camera is, the more capabilities it has. The important items you need to look for in a pinhole camera are the camera itself and an AC source.

Plus a teddy bear might not be appropriate in every setting.
