In my house, I have 14 windows downstairs spread across 3 different rooms. My current Security system has an individual sensor for each of those windows. I am currently looking into a more cost effective Security system since ADT is way more expensive than it should be on a monthly basis. I was looking at SimpliSafe and they were recommending using Motion Detectors to cover a larger area where there are multiple windows in the same room. I can cut down the 14 window sensors to 3 Motion detectors in each of those rooms. At first, I thought that it was a great idea to help cut down on the cost. When I set the Alarm to “Away” mode, that will cover the entire downstairs.

But then it dawned on me that I arm the security system when we are at home and going to sleep in a “Stay” mode where the alarm will go off if the doors or windows are opened. If I were to go with this 3 Motion Detectors option instead of having the individual Window Sensors and arm the system in “Stay” Mode, won’t I end up tripping the alarms if I go off downstairs and enter any of those rooms with the motion Sensor that is setup to point to the area where my windows are ( like the Kitchen or Family room )?

Does anyone else have this same issue while using Motion Detectors and setting your alarm in “Stay” mode at night?

Is the only option that I have to simply buy the 14 Individual sensors to cover each of the windows?

I prefer not to buy 14 more window sensors since each costs between $15 to $20 each, but if I odn’t have a workaround for this concern, then I may have to bite the bullet and factor into the total cost the purchase of 14 additional sensors on top of the 4 sensors for each of the doors.

Thoughts and recommendations appreciated.

Got a big old commercial building that is out of use. Aiming to reuse it for residential. Signs of constant trespassers on the property messing with stuff outside, I want some cameras I can leave outside, wall mounted most likely (not many places to put it up otherwise), so needs to be waterproof or at least enough for rain, and ideally can just have footage be saved onto a machine with a big SSD or HDD, whether proprietary or if I need to setup a PC. No internet available, and I am not particularly interested in having an internet connected one anyway. Cameras could be wired or wireless to the base, but would need to be able to have very long wires if they are to be wired. No intention of internal cameras at this time. Building has an old security system but it would be a while before I could even figure out how to turn it back on.

Been looking on amazon but most feels dubious or doesn’t look like it would even last outside.
