I’ve just bought an “ACT20 HD” from eBay (item number 320887938186. £45 delivered and didn’t get picked up for VAT/customs charges). Added a 16gb card from 7DayShop.
I thought I’d maybe try it as a commuter cam and use it offroad to see if I can justify a GoPro.
Pros –
Works. Has ‘commuter’ mode where it records 20 min segments until card is full then overwrites oldest.
Good ‘form factor’ – better than GoPro IMO for helmet use. Supposed to be water resistant enough for rain
Fits (just) an Exposure Joystick helmet mount (it’s a little large but seems solid. Not sure if a joystick will be safe in the mount afterwards).
Cons –
Video obviously isn’t GoPro quality – it’s AVI not h.264 format so compression is pretty heavy and you can see some blocking, esp in lower light. Having tried it on the road I understand why people read out registrations.
AVI format video needs to be converted (easy to do using free utilities) before import to iMovie.
