Hi,

I have a camera hooked up to a 9v battery and want to be able to use a
'timer switch' to turn it on at a specific time ( like the ones you
plug into a wall socket and then plug in your light socket and get it
to switch your light on automatically at a certain time when your away
)

Is there such a thing that can do this with a battery as the power
source?

Any help on this would be gratefully appreciated
