Specifications for the new 4k action cam lists the resolution as 2880x2160. How the heck can they call the resolution 2880x2160 4k? Everybody else with native 4k gives their resolution as 3880 by 2160!
I have seen at least two reviewer/bloggers who have only shown the 2880x 2160, spec. as 4 k resolution!Why don't you bother to read the specs before rushing to post. These have been posted on the SJCAM website for the past 3 or 4 weeks - easy to read. http://sjcamhd.com/product/sj7-star/ Takes only one minute's checking before you post garbage!
The SJ7 Star uses a combination of an Ambarella A12S75 chipset and a Sony IMX117 Sensor/lens - which is perfectly capable of TRUE 4K resolution.
As per the Website the following 4K and 2K resolutions are ALL possible :
4K: 3840×2160 16:9 30fps
4K: 3840×2160 16:9 25fps SuperView (Ultra Wide FOV with distortion correction)
2160P: 2880×2160 4:3 30fps
2.7K: 2704×2028 4:3 30fps
2.7K: 2704×1520 16:9 30fps SuperView
2.7K: 2704×1520 16:9 30fps
2.5K: 2560×1440 16:9 60/30 fps
1440P: 1920×1440 4:3 60/30 fps
Native footage from Pre-release models posted so far looks stunning on a 4K UHD screen.
One of the reviewer/bloggers was a guest at the Photokina Exibition ( the world's leading exposition for new photo/video equipment in EU)! Look it up!Sorry guys. So you believe unnamed "bloggers" and back street chinese stores over the official website of the manufacturer - LOL!! The device is still Pre-Sale and clearly "specifications are provisional and may change before final release" but it won't change from being a TRUE 4K camera! Despite what all your "blogger" friends say.
I have often seen total garbage about Pre-Release products - like in this thread. There is already some pre-release stuff (including video footage) from SJCAM-US.
Gearbest's ad doesn't give complete specsGreat - so I saw a camera on a crowded booth at a show and now I am more of an expert on it than the company itself!
Here is their main company store. Information - http://sjcamhd.com/sj7-star/ Specifications - http://sjcamhd.com/product/sj7-star/
Here is basically similar information from their US linked sales operation

And a real video from them on the main features and controls -
To me that's plenty of information about a product which is still in final Pre-Release?
Yup! That looks pretty complete! My sources were lacking.Great - so I saw a camera on a crowded booth at a show and now I am more of an expert on it than the company itself!

I've always found that metal things get rather hot when they sit in the sun, especially silver coloured metal buildings in the summer, unless they are well insulated on the inside. The camera can't be insulated, it needs to get rid of internally generated heat, especially an Amberella based camera!Metal body which should stand up better to hot windscreens! .
A few other cheaper boxy style action cams have been sold with aluminum housings. Is this an engineering answer to generated heat in the processor?I've always found that metal things get rather hot when they sit in the sun, especially silver coloured metal buildings in the summer, unless they are well insulated on the inside.

Judging by DCT users comments, overheating effects on plastic cases are not a problem with quality dash action cams. By the way, isn't thermoplastic a tech. advancement to combat the effects of overheating in plastic devices?Nigel - I agree that it might get just as hot - although I do try and direct aircon vents (at maximum cool) on the camera and am looking at producing some sort of shade before we get into summer here. However what I was referring to was the possibility of case distortion. The plastic case on my SJ5000x has certainly swollen and the battery is now more difficult to insert and withdraw. I do remove the battery when driving and power the unit via a car charger to cut down on over heating. Would be interested in any other comments on this.
Thermoplastic is plastic which is mouldable if you heat it up - it looses it's strength at say 90 degrees C. Obviously for use in a hot car you need to use a higher temperature variant than that!Judging by DCT users comments, overheating effects on plastic cases are not a problem with quality dash action cams.

I think it is just done for style, in fact if you have an overheating problem then using a metal case will be a bad idea as people will get their fingers burned and they will all be sent back - 40 degree C metal will feel like it is burning your fingers, 40 degree C plastic will just feel a little warm. Also, if you want the case to radiate heat away from the camera then you want it to be coloured black, not silver.A few other cheaper boxy style action cams have been sold with aluminum housings.

Most black plastic Amberella based dashcams feel fairly hot, a metal one would feel very hot, the SJ7 is Amberella based and metal!
