Seems like they've just taken ODM parts and branded it their own. For $299 AUD you can do much better than this no name Aussie distributor.
No mention of what sensor is used in the cameras, no mention of capacitor which leads me to believe it's battery only which is a no-no in the Australian Hot climate. Bad reviews of it on ProductReview Australia, so on and so forth.
I'd personally go with a trusted brand who supports it properly with firmware and after-sales support like Viofo, Thinkware or Blackvue.
