【4K 30FPS Video & 20MP Photos – Best in Good Light】 The WOLFANG GA100 records up to 4K 30FPS video and 20MP photos for travel, cycling and everyday outdoor use. For clearer detail and colour, use the camera in bright daylight and keep it steady; indoor and low-light footage may show more noise and less detail. EIS helps reduce everyday camera shake but cannot remove all vibration during fast movement or on uneven surfaces. 【40M Waterproof Housing – Camera Body Is Not Waterproof】 The included waterproof housing supports underwater use down to 40 metres when it is correctly installed and fully locked. The camera body itself is not waterproof, and the remote control must not be submerged. Before entering the water, check that the sealing area is clean, correctly positioned and free from damage; sound may be quieter or muffled while the camera is sealed inside the housing. 【MicroSD Card Required – Format Before First Use】 A MicroSD card is required for recording and is not included. Use a U3 MicroSD card with a capacity of 16–64GB and format it in the camera before the first recording. If the message “Please insert SD card” appears, format the card again in the camera or try another compatible card to avoid recording interruptions or unsaved files. 【Wi-Fi App Control & Instant Sharing】 Connect the GA100 to your smartphone via Wi-Fi for live preview, camera settings adjustment and video transfer. Please download and use the compatible app indicated in the included user manual for your camera version. The camera Wi-Fi creates a direct connection with your phone and does not provide internet access. 【Trustworthy After-Sales Service & accessory provide】We support 24 months warranty service.
