After the intruder is seen in Amelia's house the police are called. As the officer is speaking to Amelia in the kitchen she says to her that she might want to consider getting an alarm system and Amelia says "yes". You can see the touchpad to the security system behind Amelia as the officer is speaking to her. And when Amelia first enters the kitchen the green light is on on the touchpad on the wall near the door and it can be seen in the background as
the camera follows Amelia moving around. So Amelia should have said something like she needs to remember to turn on the security system. And as the officer can see the touchpad on the wall near the door behind Amelia, she should have asked about the status of the security system that is already there. Alarm touchpad by a door is common place. The scene should have been shot in another room with no touchpad or the existing security system should have been acknowledged.
