The cloud storage is mainly an event storage, which means that only event will be recorded and saved only when the camera detects movement.

If the camera supports sending notifications, open App, choose ‘Me’ > ‘Message Center’, tap the gear icon in the upper right corner of the page that appears, and then tap Enable notificationsTurn on your smart camera's alarm switch and allow notifications from App in system settings of your mobile phone.

Yes. After you add a camera to the app,ensure that the camera is online, You can then view the camera screen in the app anytime, anywhere.

Six days. When a camera records videos 24 hours a day, an 8GB memory card can be used for 18 hours, a 16GB memory caro for 36 hours, a 32GB memory card for 3 days, and a 64GB memory card for 6 days

According to the type of camera, the decision of whether to rely entirely on Wi-Fi for transmission variesFor Wi-Fi cameras: if the Wi-Fi connection is lost, the camera's operation will depend on its specific features and settings.Here are some possible scenarios:

1) Live monitoring feature: lf you are using a live monitoring camera that relies onWi-Fi to transmit real-time video streams, you will not be able to remotely view live video once the Wi-Fi connection is lost.However. Some cameras have local network capabilities that allow you to continue monitoring the camera within the local network environment.

2) Local storage feature: Some cameras come with built-in storage or support SD cards, so even if Wi-Fi is disconnected,the camera can continue recording video and store it on the local storage device.

3) Cloud storage feature: Cloud storage functionality may be affected when Wi-Fi is disconnected.

For 4G cameras, they do not rely on Wi-Fi but instead depend on data transmission via the data card provided bv the carrier. Disconnection from Wi-Fi has no impact on such devices.

You can share access with others using the "Family" feature or sharing function; once the device is already bound, attempting to bind it again will prompt that the device has been bound by someone else.

1) When connecting to Wi-Fi, most webcams only support Wi-Fi 2.4G, and a few dual-mode webcams support 5G networks.Ask the seller whether they support it or not
2) For security reasons,not all webcams can be connected via mobile phone hotspots. If you support. Ask the seller whether they support it or not.

Please check the following:
·The gateway is offline;
·The device has lost power;
·The communication distance between the device and the gateway is too far, preventing the gateway from detecting it.

Please troubleshoot in the following ways:
1) If the device statistics are always none, it should be that your device has not activated the statistics function in the cloud. You need to contact the product after-sales personnel and ask them to activate it for you. After activation, you will You can use this function normally.
2) If the data is partly missing, it may be because of your network is unstable,the device has been disconnected due to network reasons many times during the period of use,and the data cannot be counted normally during the period of the device being disconnected.

If there is still a problem,it may be that the firmware of the device is malfunctioning.Please contact the seller to let them repair the firmware of the device. Thank you for your understanding and support!

To prevent rapid battery consumption or frequent triggering, please avoid installing the device in scenes with extremely high application frequency (more than a hundred times per day).

Please check in the following ways:
1) Low-power devices (devices that use batteries are usually low-power devices)are designed for low power consumption, so the device will not report the offline status of the device in real time. Only if the device fails to report for three consecutive heartbeat cycles (the heartbeat cycle duration can be customized by the manufacturer, with the default being 4 hours per cycle) the App will display that the device is offline.(So if your sensor device has stopped working, but it still shows online in the App, you can pairing the device again to get it back to work as soon as possible.)
2) If it is the normal device powered off or disconnected from the network, the device will display offline in the App in 3 minutes, and it will display online within 30 seconds after device reconnecting to the Internet.

The distance can be up to 20 meters if there is no solid wall between them.

The indicator light will stay on for three seconds after you power on the PlR motion sensor. If the light is not working, first check the battery level, and then check whether the battery is making good contact with the device.
If the problem persists contact customer service for help.

The scooter is designed for users aged 14 and above, with a minimum height of 140 cm. Minors must ride under adult supervision. It is not suitable for pregnant women, individuals under the influence of alcohol/drugs, those with balance difficulties, or riders exceeding the weight limit (see specifications).

This is due to the zero-speed start protection enabled by default. You must push the scooter forward with your foot first, then press the throttle. This feature can be disabled in the APP settings.

·Store in a cool, dry place (ideal ~25°C).
·Do not disassemble, puncture, short-circuit, or expose the battery to fire.

Yes. Low temperatures (e.g., below 0°C) temporarily reduce battery performance and range – this is normal for lithium-ion batteries.

E1: Communication fault. Check the connection between the display and controller. Restart, reconnect cables, or replace the display if needed.
E2: Hall sensor fault. Check motor Hall wiring. Restart or replace the motor/mainboard if the issue persists.
E3: Over temperature protection. The motor exceeded 80°C (e.g., during long climbs). Stop and let it cool down.
E4: Controller fault – check for shorts, restart or replace the controller.
E5: Low voltage – charge the battery immediately.
E6 or 11 (Vicont): Stall protection. Triggered when wheels are blocked and throttle is pressed. Check motor cables or replace the motor.

Absolutely not. Only use the original factory‑provided charger. Unauthorized adapters may cause battery swelling, fire hazards and void all warranty coverage.

Fully charge the battery first. Store it indoors in cool, dry surroundings. Recharge to full capacity at least once every 90 days. Permanent over-discharge damage from neglected long‑term storage is non-warrantable.

If internal battery temperature rises above 50 °C, the battery enters thermal-protection mode and blocks charging automatically. Disconnect the charger and allow the battery to cool down before re-attempting charging.

Self-modification of frame, wiring, electronics or battery assembly is strictly forbidden. Modifications create serious safety risks and void your full-unit warranty.

Wipe surfaces with a damp soft cloth. Do NOT use high-pressure water jets, alcohol, gasoline or corrosive solvents. Turn off power and secure charging-port dust cover before cleaning to avoid short-circuit and electric shock risk. Store indoors in cool, dry areas.

It indicates abnormal battery temperature. Stop riding, power off the vehicle, and let the battery cool or warm to normal working temperature. Do not continue charging or riding while this alarm is active.

1. Inspect if water outlets are clogged by debris and check if the filter is heavily soiled.
2. Clean filter every time before and after use.
3. Manually remove large debris before running the robot.
4. Charge the unit after each use.

This means the robot has crashed. Remove it from pool, fully clean the robot, charge it for 10 minutes, then restart.

The 20-second delay is designed for the robot to sink fully to the pool bottom. If you power-on but do not submerge it, it will auto-shut-down after 5 minutes. Press power button again to restart.

1. Pull out the filter drawer from robot tail.
2. Remove the filter element.
3. Rinse thoroughly with water.
4. Re‑install filter and close the drawer.

Do NOT leave robot submerged in water all the time. Retrieve it once it arrives at pool wall to extend service life. Always clean filter, wheels and debris after every cleaning cycle.

1. Confirm the charger shows red light when plugged into AC power.
2. Wipe charging contact points clean and dry before charging (no water droplets, sand or debris).
3. If the problem persists, contact customer support.

Three selections of the cleaning modes:
