Review on Wireless Doorbell XTU Cordless Detection by Mike Roe

I have the latest J7 doorbell camera. I made an extensive comparison with my J6.1 doorbell camera. Basically they are the same size. But the J7 has a shell, I think it's rainproof and ready for new features. (tamper alarm trigger) J7 is better waterproof and safer.2. The new feature just mentioned is the tamper alarm trigger. Support told me: My phone will get an alarm notification if someone unplugs the doorbell from the case. It makes me feel safer.3. This video doorbell is completely wireless and only supports 2.4GHz WiFi connection. This is great for me because I don't want to do complicated surgeries. The remaining parameters are basically the same as for J6. All in all, this is a good update. I always look forward to new XTU products. Highly recommended! !!!!UPDATE*** After one month of use, all functions are ok. bell button. If you want to enable this feature, you need to make sure your doorbell is set correctly, otherwise the doorbell may give a false alarm. The seller told me that the principle of operation is like this: when you set the doorbell correctly, the button is pressed, and if someone wants to remove the doorbell, the button returns to its original position and the alarm sounds.
