B. The overall performance of the camera SJ4000
Sj4000 camera supports Micro SD cards around 32 gigabytes GoPro has a micro HDMI port, which is fully functional for a screening record directly on the screen. When connected, it is possible to observe a tiny HDMI cable will fit, when projecting cable is necessary to consolidate well in a good position. Micro USB contrary, fits perfectly into the interface.
SJ4000 has compared to the basic version of GoPro 1.5-inch screen, it’s a huge advantage. The latest version of GoPro Hero 4 Silver edition has also this screen, but the price but around $ 470. It is also important to emphasize that SJ4000 has a built-in Wi-Fi, you can control the camera and a mobile phone or remote control. The camera has an individual and an extremely long list of options configuration.
B1. Camera
In this area SJ4000 rather mediocre. Some of smartphone can do better photo. It is caused by imperfect chip to capture images. However, I think that in the end, this glitch will be overlooked. Functions for photographing offers various settings, but do not expect a quality big camera or photos from GoPro. This camera is simply focusing mainly on filming.
B2. Videocamera
Videocamera is much better than camera. Beautiful clear and sharp images both on land and in the water. Recording quality is worse in direct proportion to the increasing darkness, but this is the problem of most of videocameras. Wonderful thing is 170 ° lens and it`s the same as GoPro. The camera shoots 1080p @ 30fps (1920 * 1080px), but videocamera can do HD and even lower formats. Overall, we evaluated the shooting FullHD video better with SJ4000, because GoPro videocameras seem to us that it has video too much hot colors. However, the advantage is turning GoPro Full HD at 60fps.
B3. Battery and system
Battery life is the same as GoPro, it`s about one hour recording. SJ4000 camera is used with a battery of 900 mAh, and we were able to shoot with the camera less than 87 minutes. Charging takes about 2-3 hours. We recommend you to buy back up battery, these batteries are very cheap on Aliexpress.
