Test NPC EEA S71: good action camera GoPro rival

While this NPC Action camera AEE S71 are not as recorded in 4K as Hero4. But that is limited to Full HD, it is however the weight? Answer in this short test.
A quick update on the features "4K" this action cam EEA S71. His recording speed in the resolution is limited to 15 frames / s. GoPro Hero4 Black (tested here on HTO) is better, at 30 frames / sec. I recall that 4K TVs accept a rate of 60 frames / s. That said, the rate of the EEA S71 Full HD (1080p) is 60 frames / sec.
Manufacturing side, the EEA S71 has several differences with the GoPro. Its housing is made of plastic. And optics is the end of a protuberance. Used without his box, the object may be fragile. Fortunately, the box precisely supplied with the camera is strong! It looks like a bathyscaphe. I could dive into the depths of the seas with this well, but know that it is still designed to withstand a depth of 100 m! This is better than the one supplied with the GoPro.
Also sold together with the NPC EEA S71, there is the removable screen. And fortunately, because besides viewing the images, it will help better navigate in the menu with the small monochrome LCD screen.
A visible difference on this S71 EEA, it is the presence of many buttons, where the design of the GoPro is uncluttered. These buttons are supposed to improve ergonomics, handling of the device. For example, at the front, the WiFi activation buttons, changes in the extent of exposure and activation of the acceleration sensor (to start recording after detecting a shift ). But I think overall, in terms of orders, not as convenient as that. For example, why have colored green video release button? Usually, it is red. Well here the red button is the one that stops video recording. Confusing: even after several days of use, I did not yet have the reflex.
1/Video quality
I had the chance to have simultaneously test GoPro Hero4 Black and NPC EEA S71. Except in 4K mode, remember that videos generated by the EEA compete with the S71 Hero4 Black. This is the high end! This is piqued enough contrast and fluid. The colors also are relatively lively and rather warm. Is it a coincidence? No not too much. Knowing that the NPC EEA S71 has the graphics processor Ambarella ... the same manufacturer GoPro team.
2/Autonomy
The manufacturer claims that the EEA S71, the battery is 1500 mAh, can shoot for 2:30. It is not that two tests of autonomy in continuous recording mode and Full HD at 50 frames / sec showed me. A less pronounced dead battery (loaned device being passed between different hands), count rather 1:30 video recording in Full HD. Also note that the camera accepts micro SD card maximum capacity of 64GB, which is comfortable.Price 340 €.
