I'm thinking of upgrading the very cheap camera in the car after an
incident (now resolved) where a recording showing accurate time and
place would have been useful.

Looking on ebay, I see a few devices that feature wifi and GPS. I've
looked up datasheets of the Ambarella A7LA and Novatek chipsets that
seem to be most common, but on both GPS appears to be via a separate
chipset and doesn't seem to be integrated into the recorded video. So it
looks as though the cameras record pictures, but the GPS track is
recorded separately.

Is this right? I've looked on Halfords site, but the ones they offer
seem similar, just more expensive. The present cams were both under a
tenner, so I'd really like to be way below 100.

Has anyone got a cheap camera that does integrated wifi and GPS? Is the
wifi and any laptop or Android software any good?
