☑️ Checking your Wi-Fi connection
Basic shooting modes and video settings
The camera offers several recording modes, each with its own features and applications. The primary mode is video recording with a resolution of up to 1080p at 60 fps or 1440p at 30 fps. To select the resolution, go to the menu, find "Resolution," and select the desired value, keeping in mind that higher resolutions take up more space on the card.
The photo mode allows you to take photos with intervals or a timer, which is convenient for group photos or selfies. A burst mode is also available, which takes several shots in a short period of time, allowing you to choose the best moment. To activate these features, use the top button to switch to photo mode and the bottom button to select the shooting mode from the menu.
An important parameter is the field of view (FOV), which can be adjusted depending on the scene. A wide angle captures more space but can introduce distortion at the edges of the frame, a common phenomenon known as a "fisheye" effect. A narrow angle reduces distortion and brings the subject closer, which is useful when shooting from a distance.
Secrets of video quality
To improve video quality, reduce Sharpness to minimum and adjust white balance manually to suit the scene lighting.
Don't forget about Slow Motion mode, which is available at certain resolutions. This mode creates a smooth motion effect, perfect for capturing sports or falling water. However, sound in this mode is often not recorded or is distorted.
Working with a memory card and file system
Proper use of the memory card is essential for preserving your memories without interruptions or errors. The camera supports microSD cards up to 32 GB, although some users successfully use 64 GB. We recommend regularly formatting the card in the camera to avoid file fragmentation and recording errors.
Files on the card are saved in DCIM folders, where videos and photos are categorized by date or file type. When connected to a computer via USB, the camera may be detected as a webcam or storage device. It's best to use a card reader for file transfers, as transfer speeds via the camera's USB cable can be slow.
If the camera displays "Card Error" or refuses to record, check the Lock switch on the card adapter (if used) and the condition of the contacts. The issue may also be with the file system: the camera works best with the FAT32 format. When using large cards, you may need to format them to this format using specialized utilities on your PC.
Additional features and useful tips
Model SJ4000 WiFi The camera is equipped with a number of additional features, such as loop recording and a motion sensor. Loop recording allows the camera to automatically overwrite older files when the card runs low on space, making it ideal for use as a dash cam. The motion sensor starts recording only when movement is detected in the frame, saving space and battery life.
For underwater photography enthusiasts, it's important to know that without a waterproof housing, the camera is not waterproof. A waterproof housing allows diving to depths of up to 30 meters, but before each dive, it's important to check the integrity of the seals and the latches. Wiping the housing's lens of moisture and fingerprints before shooting will improve image quality.
Using external accessories such as monopods, helmet mounts, or suction cups expands your shooting options. However, be mindful of the camera's weight: mounts that are too heavy can cause the camera to tilt or become detached. Always check the camera's secure fit before engaging in active movement.
Why does the camera turn off by itself after 1-2 minutes?
This could be due to a discharged battery, overheating, or auto-off settings. Check the battery charge and disable the auto-off feature in the settings menu if it's enabled. The problem could also be with the memory card, which needs formatting.
How do I reset my camera to factory settings?
To reset the settings, go to the camera menu, find the "Reset" or "Default" option, and confirm the action. Alternatively, locate the small reset hole on the camera body (often near the USB port) and press it with a thin object while the camera is on.
Can the camera be used as a webcam for PC?
Yes, when connected via USB, the camera may be detected as a webcam. Select "PC Camera" mode in the settings menu. Image quality will depend on the drivers and software you use for video conferencing.
What to do if Wi-Fi won't connect?
Try restarting your camera and smartphone, and make sure the app has all the necessary permissions. If the issue persists, try forgetting the network on your phone and reconnecting, making sure you entered the correct password.
