I wish to run a Neos security camera from a 12v supply. The following
is from the spec sheet
Power Adapter: Input 110-240V (AC/DC) Output 5V/1000mA

What power 12v to 240v dc inverter would i require ?

5W output. And it isnt an inverter, its a reducer.

Is it likely to be as fussy as a computer would be (pure sine wave )?

Nope, it wants DC,
