I have an axis 2100 webserver cam that runs from a 12vac plugpack. I
want to run it on 12v dc and it refuses to work. It seems to want ac,
perhaps the 50hz for a clock or something.

I DONT want to have a 12v>240v inverter just to run this as
the camera will run from a car battery and solar panel so dont want
to
waste power. Can I trick the camera by somehow making a 50hz
oscillator and somehow mixing it on the gnd line of the 12v dc??
Im not sure how to do this.


Any tricks/tips/links to a circuit appreciated.

it most likely needs both a + and - voltage source internally.

Wrong. A lot of those AC powered cameras have an internal power
transformer and use a 12 VAC input to allow them to be classed as a "Low
Voltage Device" which does not require the wiring to be installed by an
electrician.
