Doesn't work

Hello I got this monitor for a gift and have been very unhappy with it's performance. I have never been able to use the movement sensor because I couldn't trust it. It was always giving false alarms so we just shut that part off and use the monitor part and even with that it contently clicks. We live in a small place and I can be in the next room over and it will click we have to position it just right at night so there's no extra notice and we can get a little sleep. Complete waste of money.
