The other (better IME) option is a LiFePo4 inline battery pack. These
are safer in hot cabin environments than ordinary lithium. They plug
inline between the fag lighter and cam (or can be hard wired) and charge
when the car is running. A decent pack should kepe a cam in parking mode
running for a day or two with no fear about flattening the main battery
or catching fire.

Not cheap mind (couple of hundred).

Any brands to look out for / avoid and why the huge markup over the cost of say
a couple of these for 20 quid and a suitable charger?

A 'genuine' Imax B6 is only 25 quid or so although not suitable for standaloen
hands off operation
