The Indicator Light Keeps Flashing Red When Adding the Camera for the First Time?

For standard SIM cards:

1. Check if the SIM card is inserted correctly. New users may easily insert it in the opposite direction.
2. Check if the SIM card is brand new. A used SIM card may not have traffic. Please contact brand after-sales customer service for assistance.
3. Ensure there are no signal interference sources around the camera and that the 4G network signal is good.

For local SIM cards:

1. Check if the SIM card is inserted correctly. New users may easily insert it in the opposite direction.
2. The camera does not support IPV6 and 5G SIM cards. Please confirm with your operator.
3. Ensure there is traffic available on the SIM card.
4. APN is incompatible. Please import the APN information of the SIM card in the APP (for specific operations, please refer to "How to obtain the APN information of the SIM card" and "How to import APN information").
5. The SIM card has a PUK or PIN code (for specific operations, please refer to "What to do if the local SIM card's PIN code is locked?").
