Maybe this is something: http://www.minicamera.nl/draadloze_spycam-p-30.html
“De spy camera kan werken met de bijgeleverde adapter of op een 9 Volt batterij doormiddel van de bijgeleverde batterij-clip.
Dat maakt deze spycam zeer geschikt voor de modelbouw ( RC auto, trein, helikopter ).”
which means
“The spy-cam can work with an adapter or a 9 Volt battery using the battery-clip. That makes this spycam very suitable for modelbouw (RC-car, train, helicopter, I don’t know the translation for modelbouw at this time).”
And. drumroll, the site has payment methods we can use. Yay! I’ll ask @ parents tomorrow, after your approval. ;)
Goodnight!
