A7 action camera teardown and review


I recently bought a very cheap action sports camera just for educational purposes only, and again just to tear it down apart and see what was behind the rectangular black plastic with lens sticking out in front. This time is an A7 Action camera bought at a local online store here in my country for just 399 Philippine peso ( $7 US dollars ). Who would not believe with that price u get

  • 30m waterproof casing
  • Handlebar clip
  • Quick snap locking bracket
  • set of velcrow strap
  • a 900mah universal battery
  • a USB connector cable
  • Selfie stick adapter
  • and a sslfie stick housing attachment
All for 399 pesos or 7 us dollars..

That is one reason I bought it for buying piece by piece you'll be paying more..All accessories I mentioned is 100% compatible with the one I am using which is this one IcoontechsIT 4K UHD sports camera. The battery can be used on it, so i already have a slight backup when i needed one.

Continue with the review was, this A7 was advertise again as 1080p. Not to be biased with the IconntechsIT brand, there is no comparison. The quality of A7 was devastating as if you are using a 2M pixel cellphone camera, not even close, since after my teardown of the said camera, it uses the OMNIVISION OV7676 cmos sensor. More on that later.

The camera do not have anything to offer but just turn it on, wait for the 2.0 inch lcd go to view mode and ready for action. press the Ok button to start recording. Menu setting no more than 20 item. That's it. Np gyro, no accelerometer, just go ahead, make my day capture thing.

Now for the teardown.


I did not put any video related on how to dismantle one. There is actually no serviceable thing inside aside from the firmware load. So if u are planning to teardown yours just for educational process, then just watch video on YouTube channels. there are too many now, you will not get lost.

Upon removal of the LCD screen cover. the main board willl have 3 small screws 2 at the bottom been removed.

The main board states
D600_MAIN_V02 20170327

Board date was the time it was made and assembled maybe not so sure bout it but maybe.

The front cover is just snap on and can be removed by flat object. there are four screws on every corner of the cover. pry up the mode button board, and you can now pull up the board.

Here is a view of dismantled parts of a working A7 camera.. See how technology is evolving and how cheap to come up with such limited components to form a working camera.

Here is the camera CMOS sensor view. As I posted up. it uses the Omnivision OV7676 that according to the data sheet that can be found here OV7676 datasheet

The maximum resolution it can handle was 720p, so no wonder the 1080p shoot settings was a crappy one. Nonentheless it shoots well with 720p on well lit area.

The processor of this A7 camera is this. I cannot find any information of the said part as of the writing but hopefully soon, I can dig up the internet for it.

And for the battery, a 3.7v 900mah lipo battery that can be used on any other clone sports camera.

There is nothing to talk much about the APPO A7 sports camera..Very cheap, sadly cheap quality too..

till next teardown.
