This is the BT Smart video baby monitor with 5 inch screen. It works with smart phones using a free app and you get wi-fi connections to your home wireless router so that you can use it. It also works with Google assistant and Amazon Alexa, It has sound level lights so you can see how loud the noise is that baby is making as well as hear it – but you can turn the sound down so you do not hear the really quiet noises. There is a 2 way audio which means that you can talk to them through the camera to soothe them back to sleep without having to go into them. You can even record clips to your smart device.
