First of all, thank you very much for choosing our product and for your feedback on our service. Secondly, I need to clarify the following: 1.When you receive the goods, the equipment is operating normally. 2. The issue of internal wiring damage you mentioned was caused by your removal of the equipment from the wall during use, which is human damage and not covered by the warranty service. 3. But in order for you to work better, I suggest that you can send us the camera and we will repair the wiring for you free of charge. You did not accept this proposal. Finally, if you are willing to return the goods, you can contact me at any time.
