So just setup my qolsys system… I have door/window sensors on all windows and doors on the first floor. I have two image/motion sensors on the first floor as well. The window sensors are instant away(group 13 I think it is), the doors are delayed entry(group 10 I think) and the image sensors are instant motion sensor group (group 17 I think ) for now. I don’t have glass break sensors at the moment. The reason I have the image/motion sensors for now is that in theory somebody could break the window glass and come through the window without opening them.
The problem is that with the image/motion sensors set to group 17(instant) is that if I just come through the door the alarm triggers. Should I set the image/motion detectors to delayed? Will the smash/crash protection prevent the problem of somebody coming through a broken window and then smashing the qolsys panel? Same as the delayed entry for the doors?
I originally went with image/motion sensors instead of glass break because my windows have curtains and I am concerned that they will muffle the breaking glass. Should I try the glass break sensors?
Maybe glass shock sensors for Qolsys? Do they exist?

To clarify, that is not how sensor Group 17 for interior follower devices functions. If you open an Entry/Exit door prior to tripping the Image Sensor, there would be no alarm during the entry/exit countdown. 17 is the correct group to use.
There are a couple possibilities here:
Based on history it looks like you my be talking about an event that happened this morning? Note that there is no Door Sensor opening prior to the Image Sensor being tripped. No entry delay was triggered. If you did open a door prior, you may have an issue with the door sensor signaling.
It looks like some other previous events suggest that a remote command was being sent to disarm after the door has been opened. Note that cellular remote commands can experience latency and you should generally be sure to send remote commands before entering.
The mobile app will not arm with a countdown, so if you are testing inside and send an arm command, as soon as the command is received the Image Sensors would be armed, as opposed to arming at the panel and having an exit delay. Generally it is best to use the mobile app to arm away after you’ve left and disarm before you’ve entered.
Would this work as a window open/close AND glass break sensor? https://www.amazon.com/Interlogix-Learn-Mode-Shock-Sensor/dp/B003Y00ZK8/ref=cm_cr_arp_d_product_top?ie=UTF8
The Shock senor linked would indeed function as a shock and open/close sensor. See the manual here.

That is great to know! Thanks!!!

Not really, just in theory from my misunderstanding of how group 17 works, but your explanation cleared that up for me. Wow, you checked my actual account activity… you guys are amazing! That one door is the door I didn’t get a sensor on yet due to the door/trim work having too large a gap at the moment, I am working on that one.
Thanks for the quick and thorough reply. I think you guys are awesome!
Do you know if that shock sensor detects glass breakage or just vibration? For example if somebody throws a rock through the glass or hit it with a hammer( I would think that would be very little vibration due to the speed it goes through the glass?? ) would that set off the sensor? Basically do you think using this sensor would achieve my goal of having protection against somebody breaking the window glass and coming through the window?

Yes, a shock sensor is intended to detect a forceful strike on the glass, whether or not it results in a shatter, but especially when it does.
Jason, I have some specific info regarding the qolsys shock sensor that I would like to discuss with you off the forum. It is info that I don’t think would be appropriate in a public forum but nothing bad. Can you please reach out to off the forum somehow so I can get you this info?
