we have a spy camera pen to record audio / video and it capacity is 4 Gb. But this is a portable and no one can understand easily of this function pen.

If interested pl.let us know.
Thanks

2G spy camera on ebay, many of them for sale from hongkong, about $30, I just bought one.

buy from hongkong only, china is OK, but hongkong is the best.

looks like a stick of gum, easily concealed
