Kind Reminder                                          
1. Heating during module operation is a normal phenomenon and can be improved by increasing the heat dissipation area and using it in a ventilated environment.
2.If you encounter image transmission lag, it may be due to network and channel interference issues. Please try changing to another channel for troubleshooting.
3. If there is a return due to the above two phenomena, please bear the round-trip shipping cost yourself. Our company only ensures that the product is used normally.
4. Provide free APP and upper computer software for easy and quick use.
5. After the module arrives, the reference source code for the upper computer APP can be provided. Please contact customer service for specific details.
