Frequently Asked Questions

1. How can I share the device with family members?

Open the app and tap on Settings. From there, you can share the device via QR code or email, and even transfer ownership of the device. The new user must first download the app and create their own account.

2. Why can't I change the settings?

Only the owner account can change settings, delete videos, and share the device. Shared accounts do not have these options.

3. How many users can view the device at the same time?

The owner account can share the device with up to 8 other accounts. Up to 3 users may view the video feed at once, but only 1 user can use the intercom.

4. Is the 5GHz Wi-Fi supported?

No, the camera only works with 2.4GHz Wi-Fi. Please separate two Wi-Fi bands by giving the 2.4GHz and 5GHz networks each a unique separate SSID (network name). Then connect your device to the 2.4GHz Wi-Fi.

5. Why is my Wi-Fi signal weak?

Your camera may be too far from your wireless router, or there may be obstructions reducing signal strength. You might want to reposition your router or get a signal extender/repeater.

6. Why is the camera offline?

The camera being offline means it is disconnected. There could be a few reasons for this:

  1. If the camera has run out of power, you will need to recharge it.
  2. The Wi-Fi signal is weak, causing disconnection. Please improve your Wi-Fi signal and reconnect the device.
  3. If the Wi-Fi is unstable, the device might go offline or experience interruptions frequently. You can try restarting the router and reconnecting the Wi-Fi to see if it helps. A good Wi-Fi connection is essential since the device is outside the house.

7. How can I adjust the human detection accuracy?

Open the app and tap on Settings. Then tap on Motion Settings. Here, you can select the desired human detection accuracy from three options: low, medium, and high. We recommend choosing medium. The high setting provides the strictest detection level, meaning the device will be triggered only when it is entirely certain that the moving object is a human. However, this stringent setting might cause the device to overlook a human figure, resulting in a missed notification.

High Accuracy – The device will record videos less frequently, ensuring maximum battery life.
Medium Accuracy – Medium battery life.
Low Accuracy – The device will record videos more frequently, leading to the shortest battery life.

If the areas you're monitoring experience excessive or repetitive motions, like children playing in the yard, you may receive numerous alerts, which can rapidly deplete the battery of devices. The human detection accuracy settings are designed to help you receive the notifications you want while preserving battery life.

8. How can I enable notifications on my phone?

  1. Open the app. From the Device page, tap the Settings icon, then tap the Motion Detection icon. Here, you can choose whether to turn Motion Alerts on or off.
  2. Open your phone's settings. Navigate to "App Management" and "Notification Settings," then locate the app. Ensure all permissions and notifications are enabled for the app.
