Very good range,
Verified Purchase(What's this?)
This review is from: Skylink PS-434W Motion Sensor (Tools & Home Improvement)
Paring this unit with an SC-100 was very easy and the instructions were quite clear.
I kept the motion sensor in its default high sensitivity mode against the advice of the manual. I tried the system in the chime mode for a few days and it has not given any false alarms, so I am planning to keep it that way. It can detect motion from quite a bit of distance in the house, inside a much wider angle than I expected, during the day and in total darkness. Fortunately, it does not get triggered by Roomba, so it seems we can leave the house with the alarm armed and schedule Roomba for a trip around the house.
It will definitely deserve its five stars if the battery lasts for a year. 4.5 if it lasts for 6 months.
