Earlier, I spotted a new SJCAM that appears to have fantastic value for money. Dubbed as the SJCAM SJ5000X Elite, this action cam supports 4K video recording and a Sony IMX078 sensor at 12 MP.
The SJCAM SJ500X Elite features a stylish sports like design to match your outdoor activities, has a 2 inch LCD screen to view and better camera navigation and powered by NTK96660 Novatek processor.
It has multiple shooting modes at 4K 30 FPS, 1080p 30 / 60 FPS, 720p 120 FPS and 240p w/ slo motion function. Another notable feature of this camera is it has a built in gyros anti shake stabilization, adjustable wide angle view lens, burst shots and rotation mode. Connectivity wise, the SJ5000X Elite is pretty complete as it has AV Out, HDMI Out and WiFi that works on both Android and IOS.
Given those specs and features, the SJCAM SJ5000X might be your GoPro alternative with 4K supports on limited budget. It's currently on pre-order for USD 149.99 internationally which is around 7K Pesos when directly converted.
