The Qolsys IQ Door Window-S is a 319.5 MHz door and window contact sensor. It will utilize S-Line rolling code encryption when paired with a Qolsys IQ Panel 2 System. This sensor is easy to install, and it reliably lets the system know when a door, window, or cabinet has been opened. However, the sensor is rather large when compared with other door and window contacts. Specifically, it is much larger than the newer and more compact Qolsys IQ DW MINI-S Sensor, while offering no additional features. And to top it off, the Qolsys IQ DW MINI-S can be obtained for less than half the price. We do not think that the Qolsys IQ Door Window-S presents a good value, and therefore we cannot strongly recommend it. That is why we give this sensor a 3-Star rating.

There are positive aspects regarding the Qolsys IQ Door Window-S. It can be easily installed, and it reliably lets the system know when it has been activated. We appreciate the fact that the sensor utilizes S-Line rolling code encryption when paired with the Qolsys IQ Panel 2, and we also like the fact that it is backwards compatible with other 319.5 MHz security systems. If you already have an existing Qolsys IQ Door Window-S, then you can continue to use it without issue.

But the downsides of the Qolsys IQ Door Window-S are very apparent when you look at other similar sensors. The Qolsys IQ Door Window-S is very bulky for a door/window contact sensor, and many users may want to find a more discreet option, such as the Qolsys IQ DW MINI-S. We also think this sensor is overpriced, and there are multiple less expensive options readily available. The fact that this sensor uses a CR2 battery is somewhat weird, as that really isn't a commonly used battery type. You will need to replace the battery every three (3) to five (5) years, which is fairly common for a sensor of this type. Still, there are just too many downsides and flaws for us to really recommend this sensor. For those reasons, it gets 3 Stars from Alarm Grid.

Good: Easily Installed, Reliable, S-Line Encryption, Backwards Compatible w/ Legacy 319.5 MHz Systems

Bad: Bulky, Overpriced, CR2 Battery, Short Battery Life

Bottom Line: 3 Stars
