Wi-Fi Hidden Camera Alarm clock

I have a husband with early onset dementia.  I have set up several cameras so that I can check in on him when I am away from the  house.  Thankfully this one works well and looks just like an alarm clock.  I can turn it on for just a minute to make sure he is in bed and know that he is not wondering.  It has a good Wi-Fi distance unlike some others I tried first.  The only problem is that it switches from the time, to the date, to what used to be a temperature reading constatnly.  There is no way to turn off this feature.  So far it has not bothered him.  It give me peace of mind and I don't disturb him when he's sleeping.
