The application was installed easily, the sensor was determined too without dancing with a tambourine. The alert comes somewhere in a second or two after the disconnection. Batteries are not included) in general I recommend;-)

The product corresponds to the description. Easy to set up with Tuya. The camera records video with voice, night/day, the video quality is good, the sound is legible. The door sensor is working. Recommend.

Well received, fast delivery, well packaged, after the first Test it works well but since the two surfaces of the door are not in the same level I note a disturbance of the detection

Made well, small, convenient installation. Respond clearly and quickly back less than 1 second. The Tuya application allows a bunch of settings to create automotivation.

I think it's a ballet thing. Velcro flies away, it falls off the door periodically. Works when turn on. Through Time. I think I don't need him. Waste of money
